I have been trying to find documentation on ipvsman. The only link I can find is: http://wiki.inqbus.de/twiki/bin/view/Ipvsman/Dokumentation. That link does not work. Can you please let me know where I can find some documentation for it? In particular, how can I define direct route services in service.cfg? No matter what I do, the service I put to this file is interpreted as NAT. Also, what is topology.cfg for? Thank you very much for your help.

That was why I wanted to use ipvsman. I want a simple tool that monitors the real servers and revises the LVS table so traffic will not routed to dead servers. Any recommendations?

Is there a particular reason why periodic updates would not work?

There are=A0some conflicting answers to this question on the FAQ and = mailing list (in gernal, it helps with the system as a whole). In our actua= l usage=A0experience, it appears SMP helps, since it did reach 160 CPU usag= e. However, I do not know if this is real or just an illusion. I do not kno= w if LVS is actually doing real work that caused the usage to be above 100 = or is it because of SMP that causing locks that resulted that. Also, in our= limited testing of the new setup, we find the SMP helps because with 8 NIC= s, just to process the interrupts can overwhelm a single CPU (core). Can anyone share their knowledge or experience for the following: =A01. Can LVS increase linearly in capacity when we go from the setup we cu= rrently have (2 cores with 2 NICs) to what we are considering (8 cores, wit= h 8 NICs) =A02. Has anyone else used similiar setup that can share their experience? = There was a posting to the mailing list in Dec. 2007 that indicated the per= formance limit is ~450K (don't know if it's the sum of InPPS and OutPPS)=A0= pps. There was no conclusive answer as to this was the limit of LVS or not =A03. Has anyone have a setup that can process 1+ million pps (LVS-NAT) on = a single LVS machine (we already use multipel LVS with keepalived in a live= -live configuration)?

You can make a given interrupt (or device driving interrupts) have an affinity with a single processor core. Generally speaking, interrupts are shared more or less equally across all cores so more cores should scale performance well; however in some circumstances it can be beneficial to assign a given interrupt driver to a specific core so you then know where the load on that core is coming from. I should point out that the OP stated a "usage" (which I assume to mean % CPU utilisation) of 160 - that's a good thing. There's no point having a totally idle CPU! When utilisation hit 160%, what was the 1/5/15 minute load average?

What I would like to know is how w= ell can LVS code scale with multiple CPU. I do not know that balancing out = IRQ with the NIC works pretty well with Linux 2.6.18 kernel. Certain Broadc= om NICs seem to have problem with MSI turned on, but Intel NICs works fine.= So, *assume* the kernel can linearly scale up with SMP with NICs' interrup= ts, can the LVS code do the same? Jason, handling of NIC interrupts does balance over multiple CPU when you e= ither manually set the SMP affinity or use irqbalance. Graeme, it's a good thing the CPU is being used, but I expect our traffic t= o increase dramatically, so there is not much room left for growth. That's = why we are considering something much "beefier" to handle the load. The loa= d (1/5/15)=A0average on the machine is almost nothing when CPU usage is at = 160%. It is mostly taken up by Soft IRQ. =A0 ----- Original Message ---- From: New User To: lvs-users@linuxvirtualserver.org Sent: Tuesday, March 3, 2009 1:45:12 PM Subject: LVS performance on SMP Hi, We are currently running=A0dedicated LVS-NAT (with the exception of iptable= s): =A0Intel Xeon 3060 @ 2.4GHz (2 cores) =A02G RAM =A02 Gb/s NIC (one external, one internal) =A0LVS-NAT =A0Linux 2.6.18 kernel It appears we are running out of CPU (usage reached 160, with 40 idle, 2 co= res) when we reach: =A0~10K CPS =A0~100K InPPS =A0~120K OutPPS =A0~1 million+ active and number of objects in the ip_vs_conn entry in /pro= c/slabinfo We are considering upgrading the setup to the following: =A02 x Intel Xeon 5430 (2 CPUs, 4 cores each) =A08G RAM =A08 Gb/s NIC (4x1Gb in bonding for external, 4x1Gb in bonding for internal) =A0LVS-NAT =A0Linux 2.6.18 (possible newer if it offers performance increase) The question is how well can the LVS=A0code take advantages of the multiple= CPU.

What I would like to know is how well can LVS code scale with multiple CPU. I do not know that balancing out IRQ with the NIC works pretty well with Linux 2.6.18 kernel. Certain Broadcom NICs seem to have problem with MSI turned on, but Intel NICs works fine. So, *assume* the kernel can linearly scale up with SMP with NICs' interrupts, can the LVS code do the same? As it's a part of the kernel, the answer is "yes". However the more stuff you ask the kernel to do (ie. the less simple the packet path is through the stack), the lower the throughput will be. It this was a simple router you'll get throughput A pps. Adding LVS on top reduces A depending, again, on complexity - persistence maps, timeouts, the number of realservers. Adding (for example) netfilter/iptables rules reduces A further, and we all know that adding in conntrack features or modules will reduce it even further. One of the problems Linux has in general is that no two systems are alike, so benchmarking things is almost impossible in reality. I'd be very interested to see if you make your interfaces have affinity with a single CPU core whether your usage drops, because once they're locked they're avoiding softirq...

Quite possibly due to different configuration you may be running. It will be interesting to see if you haven't dropped incoming traffic at this level of PPS. Please let us know if that is the case. We run 2 NICs in bonding mode (Active/Passive) for both incoming and outgoing traffic. Our CPU level are very low ~5% (all of it is system) at 174K in and 174K out PPS. We run ldirector & heartbeat in DR mode. Hardware is comparable to yours. We had an issue of machine dropping packets when we were using boradcom nics. We replaced them by intel cards and adjusted ring parameters using ethtool. We do not do iptables on the system and that could be the one eating up CPU, you may want to take a look at these parameters. Does kern.log says kernel table full at such level of traffic ? # Adjust iptables related timeout to reduce number of connection in kernel tables net.ipv4.netfilter.ip_conntrack_tcp_timeout_time_wait=10 net.ipv4.netfilter.ip_conntrack_tcp_timeout_fin_wait=10 Good luck and share your findings here on the list. -Sashi On Mar 2, 2009, at 9:45 PM, New User wrote: > Hi, > > We are currently running dedicated LVS-NAT (with the exception of > iptables): > Intel Xeon 3060 @ 2.4GHz (2 cores) > 2G RAM > 2 Gb/s NIC (one external, one internal) > LVS-NAT > Linux 2.6.18 kernel > > It appears we are running out of CPU (usage reached 160, with 40 > idle, 2 cores) when we reach: > ~10K CPS > ~100K InPPS > ~120K OutPPS > ~1 million+ active and number of objects in the ip_vs_conn entry > in /proc/slabinfo > > We are considering upgrading the setup to the following: > 2 x Intel Xeon 5430 (2 CPUs, 4 cores each) > 8G RAM > 8 Gb/s NIC (4x1Gb in bonding for external, 4x1Gb in bonding for > internal) > LVS-NAT > Linux 2.6.18 (possible newer if it offers performance increase) > > The question is how well can the LVS code take advantages of the > multiple CPU.

The short story is that I'm running ubnutu 8.04 LTS x64. I'm trying to set up ldirectord on a standalone box for now(I'll juice it up with heartbeat in a few weeks). Below is a quick list of configs and outputs. The problem I'm running into is that, while ipvsadm shows my VIP and RIP's all up and functioning, nothing is listening on the VIP:port shown by ipvsadm -L -n. I've followed http://www.howtoforge.com/set-up-a-loadbalanced-ha-apache-cluster-ubuntu 8.04 as my setup guide, save that I didn't add heartbeat to the mix.

Hi Tim, the quick answer to your question is that ldirectord isn't supposed to bind to VIP:port and this shouldn't be a problem. The slightly longer answer is that ldirectord effects load balancing by configuring LVS, which lives in the kernel and acts much more like a router than a proxy. As such, it does not bind a socket to VIP:port. Rather, as packets pass through the kernel's networking code they will be processed by LVS if they match the VIP:port specified _and_ those packets would otherwise have been delivered to a local process (this is one area where LVS isn't quite like a router). Typically second criteria is satisfied by placing the VIP on a local interface. -- Simon Horman VA Linux Systems Japan K.K., Sydney, Australia Satellite Office H: www.vergenet.net/~horms/ W: www.valinux.co.jp/en _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-request@LinuxVirtualServer.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users From lvs-users-bounces+archiver=linux-vs.org@linuxvirtualserver.org Wed Mar 4 07:58:27 2009 Return-Path: X-Original-To: archiver@linux-vs.org Delivered-To: archiver@dragon.linux-vs.org Received: from localhost (localhost.localdomain [127.0.0.1]) by dragon.linux-vs.org (Postfix) with ESMTP id 3AD4525C009 for ; Wed, 4 Mar 2009 07:58:27 +0800 (CST) Received: from dragon.linux-vs.org ([127.0.0.1]) by localhost (dragon.linux-vs.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 15177-04 for ; Wed, 4 Mar 2009 07:58:23 +0800 (CST) Received: from boom.graemef.net (boom.graemef.net [82.113.154.29]) by dragon.linux-vs.org (Postfix) with ESMTP id 694AF25C004 for ; Wed, 4 Mar 2009 07:58:22 +0800 (CST) Received: from localhost ([127.0.0.1] helo=boom.graemef.net) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LeeUN-0006Nn-2N; Tue, 03 Mar 2009 23:57:31 +0000 Received: from mail-ew0-f167.google.com ([209.85.219.167]) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LeeUH-0006NZ-KK for lvs-users@linuxvirtualserver.org; Tue, 03 Mar 2009 23:57:28 +0000 Received: by ewy11 with SMTP id 11so2565679ewy.11 for ; Tue, 03 Mar 2009 15:57:24 -0800 (PST) Received: by 10.210.67.4 with SMTP id p4mr571385eba.63.1236124644130; Tue, 03 Mar 2009 15:57:24 -0800 (PST) Received: from kaglaptop (f62230.upc-f.chello.nl [80.56.62.230]) by mx.google.com with ESMTPS id 7sm674276eyg.47.2009.03.03.15.57.20 (version=SSLv3 cipher=RC4-MD5); Tue, 03 Mar 2009 15:57:22 -0800 (PST) Message-ID: <49adc3e2.0707d00a.2d7a.23b4@mx.google.com> From: "Kit Gerrits" To: "'LinuxVirtualServer.org users mailing list.'"

Thanks for any help or ideas you can give. _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-request@LinuxVirtualServer.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-request@LinuxVirtualServer.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users From lvs-users-bounces+archiver=linux-vs.org@linuxvirtualserver.org Wed Mar 4 08:26:44 2009 Return-Path: X-Original-To: archiver@linux-vs.org Delivered-To: archiver@dragon.linux-vs.org Received: from localhost (localhost.localdomain [127.0.0.1]) by dragon.linux-vs.org (Postfix) with ESMTP id AFED725C009 for ; Wed, 4 Mar 2009 08:26:44 +0800 (CST) Received: from dragon.linux-vs.org ([127.0.0.1]) by localhost (dragon.linux-vs.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 16092-05 for ; Wed, 4 Mar 2009 08:26:42 +0800 (CST) Received: from boom.graemef.net (boom.graemef.net [82.113.154.29]) by dragon.linux-vs.org (Postfix) with ESMTP id 0203825C004 for ; Wed, 4 Mar 2009 08:26:41 +0800 (CST) Received: from localhost ([127.0.0.1] helo=boom.graemef.net) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LeevY-00075o-T9; Wed, 04 Mar 2009 00:25:37 +0000 Received: from hosted06.westnet.com.au ([203.10.1.221]) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LeevU-00075d-SK for lvs-users@linuxvirtualserver.org; Wed, 04 Mar 2009 00:25:34 +0000 Received: from hosted06.westnet.com.au (hosted06.westnet.com.au [127.0.0.1]) by hosted06.westnet.com.au (Postfix) with SMTP id 9B4F4223907 for ; Wed, 4 Mar 2009 09:00:23 +0900 (WST) Received: from carnifex.staff.wn.com.au (unknown [192.168.59.10]) by hosted06.westnet.com.au (Postfix) with SMTP id D9957222F42 for ; Wed, 4 Mar 2009 09:00:22 +0900 (WST) X-MimeOLE: Produced By Microsoft Exchange V6.5 Content-class: urn:content-classes:message MIME-Version: 1.0 Date: Wed, 4 Mar 2009 09:00:22 +0900 Message-ID: X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-topic: Real and Fallback in Piranha Thread-Index: AcmcXGRZB8jS1ewUS4mdRtEQtd834A== From: "Sean Drill" To: X-PMX-Branch: TNG-Outgoing X-Content-Filtered-By: Mailman/MimeDel 2.1.9 Subject: [lvs-users] Real and Fallback in Piranha X-BeenThere: lvs-users@linuxvirtualserver.org X-Mailman-Version: 2.1.9 Precedence: list Reply-To: "LinuxVirtualServer.org users mailing list."

As we currently run our system, we have two servers each running ldirectord/heartbeat, we have active/standby servers for load balancing, but we also run the virtual servers as active/standby (or real/fallback in the ldirectord terminology) I have been able to replicate the active/standby for the servers, but cannot see how I can do active/standby with the virtual servers. I attempted to set one of the real servers to a priority of 0 and the other priority 1 whilst using WRR as the load balancing method. Strangely I still continued to see connections directed to the server with the priority of 0, which runs in direct contradiction to how I understanding the priority system works (I understood priority 0 means accept no new connections) Anyone who can offer some assistance would be greatly appreciated.

Our current configuration is configured using ldirectord. The active node hosts all the virtual servers. Each virtual server will have an active real server, and a backup real server. All the traffic will be directed to the active real server, unless that server becomes unreachable, at which point all traffic will be directed to the backup server. I am however only able to get piranha/lvs to do load sharing. In this case as long as both servers are set to UP, then traffic will be balanced between all servers (determined by load balancing scheme and weighting.) What I am attempting to do is create a virtual server in LVS, which has two active REAL servers, however direct traffic only to one of them, unless otherwise directed or if the active member fail, then direct traffic to the backup. I hope this is a little clearer Regards - Sean -----Original Message----- From: lvs-users-bounces@linuxvirtualserver.org [mailto:lvs-users-bounces@linuxvirtualserver.org] On Behalf Of Sebastian Vieira Sent: Wednesday, 4 March 2009 4:11 PM To: LinuxVirtualServer.org users mailing list.

Unfortunately this is the wrong list to ask about usage of Piranha - there's a separate list for RedHat's tools: https://www.redhat.com/mailman/listinfo/piranha-list ...but as I've said before on this list, it's pretty quiet there. With no knowledge whatsoever of Piranha I'd say you could go a long way towards achieving your aim by using WRR with weights of (say) 9999 for one server, and 1 for the other. It won't be a completely hot/cold system but it will get fairly close.

This is covered in some depth in the LVS HOWTO. The short explanation is that this isn't possible; the longer answer is that it might be, but it depends very much on your requirement and local circumstances as to whether you can make it work. Most notably, using LVS-DR requires the VIP to be bound to a loopback/dummy/other adapter on the realservers (httpd servers in your case) which would result in all connections from those servers to the VIP being handled locally.

Basically, the first RS is on it's own in the pool, and the second RS is defined as a sorry server, or failback, depending on the vocabulary. Here is an example using keepalived. The first virtual service (fwmark 10) is a load balancing across the 2 RS, and the second (fwmark 11) is in active/passive.

Now I am turning to lvs/nat for some research and find that the thought behind lvs/nat is quite simple and easy to understand. I am not familiar with F5 loadbalancing products and only have a basic understanding that they (F5) are basically NAT devices (when we use them in layer 4 loadbalancing solutions). Can someone give me a clear and simple picture of the difference between F5 NAT solution and LVS/NAT mode? Any links to the documentation of F5 solutions will be welcomed. Thank you in advance.

On Real server1 we set the default gateway as 10.0.0.9, also we have iptables with no rules at all.(Default ACCEPT). I know it works well if clients from outside world access services provided on VIP:80. But what happens on loadbalancer (which has no iptables NAT rules in itself) if real servers(10.0.0.10) in lvs/nat as a client to access Internet(111.111.111.111:22)? How are the packets changed or handled on loadbalancer when it receives requests from 10.0.0.10 with a dst address 111.111.111.111 dst port 22 and receives responses from 111.111.111.111?

Changelog looks like : 2009-03-05 Alexandre Cassen * keepalived-1.1.17 released. * Fixed low-level scheduler timer computation to take care to monothonic computation. Select returns if timer is null! * VRRP : Fixed vrrp script initialization to use event thread instead of timer thread so that script no longer need to wait until first polling timer fired. * VRRP : Willy and I fixed MII media link failure detection to test SIOCGMIIREG call before fetching BMSR. * VRRP : Resurected VRRP_STATE_GOTO_FAULT. This state is really needed to speed-up convergence and prevent against any issue while using vrrp_sync_group. regs, Alexandre _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-request@LinuxVirtualServer.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users From lvs-users-bounces+archiver=linux-vs.org@linuxvirtualserver.org Thu Mar 5 18:04:44 2009 Return-Path: X-Original-To: archiver@linux-vs.org Delivered-To: archiver@dragon.linux-vs.org Received: from localhost (localhost.localdomain [127.0.0.1]) by dragon.linux-vs.org (Postfix) with ESMTP id 7D36B25C00A for ; Thu, 5 Mar 2009 18:04:44 +0800 (CST) Received: from dragon.linux-vs.org ([127.0.0.1]) by localhost (dragon.linux-vs.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 24908-10 for ; Thu, 5 Mar 2009 18:04:39 +0800 (CST) Received: from boom.graemef.net (boom.graemef.net [82.113.154.29]) by dragon.linux-vs.org (Postfix) with ESMTP id 17EF525C003 for ; Thu, 5 Mar 2009 18:04:11 +0800 (CST) Received: from localhost ([127.0.0.1] helo=boom.graemef.net) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LfAPT-0007IT-Vt; Thu, 05 Mar 2009 10:02:36 +0000 Received: from mail-bw0-f163.google.com ([209.85.218.163]) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LfAPM-0007II-JT for lvs-users@linuxvirtualserver.org; Thu, 05 Mar 2009 10:02:31 +0000 Received: by bwz7 with SMTP id 7so3812001bwz.11 for ; Thu, 05 Mar 2009 02:02:27 -0800 (PST) MIME-Version: 1.0 Received: by 10.223.122.15 with SMTP id j15mr798852far.10.1236247346841; Thu, 05 Mar 2009 02:02:26 -0800 (PST) In-Reply-To: <3E4AB0D03DDE406BAEBC01D776F9E56B@xufeng> References: <3E4AB0D03DDE406BAEBC01D776F9E56B@xufeng> Date: Thu, 5 Mar 2009 10:02:26 +0000 Message-ID: <5ca0b08d0903050202g3241184ap4b685a3a30284445@mail.gmail.com> From: Malcolm Turnbull To: "LinuxVirtualServer.org users mailing list."

E.g., 172.16.1.153:180(the host running ldirectord) balances to 172.16.1.153:2500-2502. Here's the configuration: # Global Directives checktimeout=3 checkinterval=10 quiescent=no logfile="/var/log/ldirectord.log" autoreload=yes virtual=172.16.1.153:180 real=172.16.1.153:2500 masq real=172.16.1.153:2501 masq real=172.16.1.153:2502 masq scheduler=wlc service=none persistent=30 checktype=connect protocol=tcp When I run a tcpdump to watch incoming traffic, 172.16.1.153 sends back a RST packet for any incoming requests. Ipvsadm seems to think everything is hunky dory. IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP 172.16.1.153:180 wlc persistent 30 -> 172.16.1.153:2502 Local 1 0 0 -> 172.16.1.153:2501 Local 1 0 0 -> 172.16.1.153:2500 Local 1 0 0 I have set up IP forwarding and all the /etc/modules ip_vs_*.ko and such. I've tried changing the real servers to 127.0.0.1, but that didn't make a difference. I'm afraid I'm missing something simple here, but I just can't seem to get it going. Thanks for any ideas.

I would have thought that someone would have tried this by now, but I can't remember whether they did or not. So I can't say no off the top of my head. If the packets did get rewritten on the way in, you'd have to rewrite the reply packet on the way back.

' on http://kb.linuxvirtualserver.org/wiki/Performance_and_Tuning and it points out that 'We can configure the size of IPVS connection hash table before compiling the Linux kernel.' Is there another way to tune this parameter (IPVS connection table size) besides recompiling the Linux kernel?

Unfortunately not, no. There was a thread either here or on lvs-devel a few weeks ago about this very factoid. Of course, if you have everything modular then all you need is the recompiled module (rather than the whole kernel) but that's an exercise for the reader :) Graeme _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-request@LinuxVirtualServer.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users From lvs-users-bounces+archiver=linux-vs.org@linuxvirtualserver.org Fri Mar 6 20:42:06 2009 Return-Path: X-Original-To: archiver@linux-vs.org Delivered-To: archiver@dragon.linux-vs.org Received: from localhost (localhost.localdomain [127.0.0.1]) by dragon.linux-vs.org (Postfix) with ESMTP id 933CE25C007 for ; Fri, 6 Mar 2009 20:42:06 +0800 (CST) Received: from dragon.linux-vs.org ([127.0.0.1]) by localhost (dragon.linux-vs.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 24915-07 for ; Fri, 6 Mar 2009 20:42:04 +0800 (CST) Received: from boom.graemef.net (boom.graemef.net [82.113.154.29]) by dragon.linux-vs.org (Postfix) with ESMTP id BE47225C004 for ; Fri, 6 Mar 2009 20:42:02 +0800 (CST) Received: from localhost ([127.0.0.1] helo=boom.graemef.net) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LfZBl-0002P6-Cl; Fri, 06 Mar 2009 12:30:05 +0000 Received: from wm7d.net ([216.23.171.251]) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LfZBf-0002Ot-Dq for lvs-users@linuxvirtualserver.org; Fri, 06 Mar 2009 12:30:00 +0000 Received: from localhost (localhost [127.0.0.1]) by wm7d.net (Postfix) with ESMTP id 9A84EF6592 for ; Fri, 6 Mar 2009 04:29:55 -0800 (PST) X-Virus-Scanned: by amavisd-new at wm7d.net Received: from wm7d.net ([127.0.0.1]) by localhost (wm7d.net [127.0.0.1]) (amavisd-new, port 10026) with ESMTP id LfNLoWKsSWpq for ; Fri, 6 Mar 2009 04:29:52 -0800 (PST) Received: by wm7d.net (Postfix, from userid 1004) id 377A0F65E4; Fri, 6 Mar 2009 04:29:52 -0800 (PST) Received: from localhost (localhost [127.0.0.1]) by wm7d.net (Postfix) with ESMTP id 277A9F6592 for ; Fri, 6 Mar 2009 04:29:52 -0800 (PST) Date: Fri, 6 Mar 2009 04:29:52 -0800 (PST) From: Joseph Mack NA3T To: "LinuxVirtualServer.org users mailing list."

I've read the article in the how to some time ago and my basic understanding is that if we leave the bucket at the default there is no real fear of loosing any connections as long as we have enough ram (as each of the buckets can have any number of connections). So is the assumption that large amounts of memory (2gb+) should be able to handle pretty much an unlimited number of connections? ________________________________ From: lvs-users-bounces@linuxvirtualserver.org on behalf of Joseph Mack NA3T Sent: Fri 3/6/2009 4:29 AM To: LinuxVirtualServer.org users mailing list.

Ignoring memory taken by the kernel, apps etc, you can have 2G/112 simultaneous connections. Changing the number of buckets doesn't change the number of connnections that can be stored, only the number of buckets in which they're stored.

I have a two-interface configuration on my director, where each interface is on a different subnet -- an internal interface with the realservers, and an external one with the VIPs. Using LVS-NAT, SYN packets are correctly routed by the director to an appropriate realserver and ACKs are appropriately routed back to the director from the realclient (via the default gateway) -- but when the director emits the demasqueraded ACK to be sent to the client, it does so on the internal interface rather than the external one, and the router between the two (which I don't control) is disinclined to forward it. I've tried to work around this using source routing, as follows: # ip rule show 0: from all lookup local 32764: from lookup int 32765: from lookup ext 32766: from all lookup main 32767: from all lookup default # ip route show table ext dev eth1 scope link default via dev eth1 # ip route show table int dev eth0 scope link default via dev eth0 As the demasqueraded packets have a source address on , I would expect them to leave on eth1 via . However, this does not happen -- the demasqueraded packet attempts to leave via eth0, and thus never reaches its destination.

You should only very rarely have two defaults. If you make sure your box has a single default route via EXTERNAL_GW then your problem will resolve itself.

That looks to me very much like an interrupt-handling issue. What architecture are your NICs using - PCI, PCIe etc etc? Are they on board using a common bus? I'd surmise that either they're on a common PCI bus which is saturated, or they're sharing an IRQ and just can't go any faster. Can you separate them (either in BIOS or driver)? You might want to look back at CPU affinity which was discussed recently, although you say this a Celery so that throws out SMP magic as a fix!

(MOST client computers are on the other side of the director on eth0.) The VS is configured on eth0 in LVS-NAT mode. Clients on the "outside" connect through the director to the RS fine. The one client on the inside cannot connect through the VS on eth0. It just times out. I looked into this once before and it has to do with icmp redirects, local routing, ARPs, and so on. Bottom line is that the client's SYN packet gets redirected through LVS, but the server's SYN-ACK goes straight to the client since they are both on the same segment. The client ignores it because it comes from the wrong IP address.

I know it's not as straightforward or reliable as TCP, but in most environments it should give much more useful results than "none" or "ping". Netcat seems to have no problem figuring out if something is listening on an UDP port: --- auth01:/etc/heartbeat# nc -v -u -z 10.0.0.2 1813 10.0.0.2: inverse host lookup failed: Unknown host (UNKNOWN) [10.0.0.2] 1813 (radius-acct) open auth01:/etc/heartbeat# nc -v -u -z 10.0.0.2 1814 10.0.0.2: inverse host lookup failed: Unknown host (UNKNOWN) [10.0.0.2] 1814 (?) open auth01:/etc/heartbeat# nc -v -u -z 10.0.0.2 1815 10.0.0.2: inverse host lookup failed: Unknown host (UNKNOWN) [10.0.0.2] 1815 (?) : Connection refused --- It would be really nice to see this in a future version so that any UDP service can be somewhat monitored. While hacking this into the installed ldirectord seems easy enough the likelihood of it being overwritten by a security update during the lifetime of these servers is just too high. So for the here and now, I guess the external "misc_check" of keepalived might be better suited?

We received a further slew of attempts to send similar messages, which were prevented by the application of their mod bit. Apologies once again, all.

The Backup LVS only get virtual IP if the two interfaces of the Mster LVS fails. 2) Configurfation 2: primary=3Dxxx.xxx.xxx.xx1 backup=3Dxxx.xxx.xxx.xx2 ,= in this scenario Backup LVS only get get virtual IP if the primary=3D IP of t= he Mster LVS fails. This is a default behavior? I need that backup LVS gets virtual IP when any network (cable or interface) fails at the Primary LVS.

I've got three VMs -- two "real" servers, one LVS router. Everything appears to start up correctly, 'ipvsadm -L' looks like I think it should, but the routing from the VIP to the real servers just plain isn't happening. Network connectivity between the router and real servers works fine, but I can't even connect to the VIP on port 80. Following Redhat's documentation, I've tried both the iptables PREROUTING and the arptables methods, but neither has worked. I'm sure I've made a silly mistake, but I can't for the life of me figure it out. And LVS's logging is so quiet that I'm not getting much; all appears to be working according to the logs.

It's as good a place as any, but it doesn't really explain the basics very well - it's a sort of "click here, do this, all will be well" approach which doesn't give you the full grounding about the "why" (or even the "how" in some cases!). > I have now, and none of them seem to be my problem. Many are little > bugs or resource allocation issues, but they all appeared to be > problems that exhibited themselves once things were at least > marginally working. In my case, I can't even get the dang thing > working at all. I would normally ask for all sort of debug info here, but as you already stated this is a test platform I'm going to ask you to completely clear the RH-driven configs and start from a clean slate. BTW, I feel it's your VIP netmask causing the problem, but we'll come to that later... What you'll need to do is as follows: # /sbin/ip address add 10.9.3.6/32 dev eth0 # /sbin/ipvsadm -A -t 10.9.3.6:80 -s rr # /sbin/ipvsadm -a -t 10.9.3.6:80 -r 10.9.3.1:80 -w 100 -m # /sbin/ipvsadm -a -t 10.9.3.6:80 -r 10.9.3.2:80 -w 100 -m That then gets you a very basic virtual server on 10.9.3.6:80/tcp which has realservers on port 80/tcp on addresses 10.9.3.1 and 10.9.3.2, using the "masquerade" method (LVS-NAT). The prerequisite for this is that the realservers have a default gateway address pointing to the director, ie. 10.9.3.6. Once you have this set up, you can try to access the VIP from a client which is *not on the same LAN as the VIP or the realservers*. This is a key point - the return traffic MUST go back via the director in LVS-NAT or the SYN/AYN-ACK/ACK handshake will fail. Please try this and let us know how you get on. By the way, if your VIP netmask is too wide on the director then the director will believe that a Very Large Network is local to it or immediately adjacent. That can stop normal traffic flow dead, right there.

This is undesirable in environments where inter-RS traffic is high, as with clustering and data replication. I decided NOT to disable redirects OR remove the local LAN routes from the RealServers. Instead, I just added explicit routes from each RS to my client machine through the director and did the same on the client. I figured I could live with some redirect traffic. It worked fine, and as a side effect I noticed that no redirects were being sent by the director machine anyway. Running sniffers simultaneously on the client, the director, and the server, I observed no ICMP redirects being sent or received. The traces also showed that requests and responses were in fact passing through the director and being properly NATed. You might want to consider adding a note to the One Network LVS-NAT HOWTO indicating that if someone only has a few clients that need to access RealServers on their own subnet through a director, using static routes on each client and RS seems to be a better approach. -- Eric Robinson Disclaimer - March 21, 2009 This email and any files transmitted with it are confidential and intended solely for LinuxVirtualServer.org users mailing list..

Okay, I did that, and the result is -- improved? I think? I can see the HTTP request in the logs of one of the real servers. So the request gets that far. But the response apparently never reaches the client; curl just sits waiting until it finally times out. I _was_ testing from a different subnet. I can ping the client from the real servers, so at least some of the networking magic appears to be working fine.

No, all I configured wasa route from the real servers to the client going through the director. I'm not sure how to force that behavior, either, without creating a VLAN with no default route to the outside world. When pinging the real servers from the client, our routers are quite happy to route the packets directly to the real servers. I don't control the network here, so that's not an option -- and, incidentally, as I don't intend to use LVS-NAT in production, I think it'd be kind of counterproductive to jump through those kinds of hoops to get this working. That said, I'm not sure why packet routing from the client to the real servers should matter; in the test I was doing, I was requesting the VIP from the client; the director passed the request on to a real server; and the real server routes its replies through the director. At no time during that test should the client _try_ to communicate directly with the real server, so I'm not sure why that matters.

I think? Righto, so you're seeing something good(ish). Although you then go on to say in response to Joe's message that you're not intending to use NAT in production, so it would be productive now to switch to the method you are intending to use which I assume will be -DR. In that case, please clear the director's config (ipvsadm -C) and switch it to -DR mode instead: On the director: # /sbin/ip address add 10.9.3.6/32 dev eth0 # /sbin/ipvsadm -A -t 10.9.3.6:80 -s rr # /sbin/ipvsadm -a -t 10.9.3.6:80 -r 10.9.3.1:80 -w 100 -g # /sbin/ipvsadm -a -t 10.9.3.6:80 -r 10.9.3.2:80 -w 100 -g On the realserver(s): # /sbin/ip address add 10.9.3.6/32 dev lo Add the following to /etc/sysctl.conf: # LVS switches net.ipv4.conf.lo.arp_ignore = 1 net.ipv4.conf.lo.arp_announce = 2 net.ipv4.conf.all.arp_ignore = 1 net.ipv4.conf.all.arp_announce = 2 Then do # sysctl -p Then see what you get from your clients. Note that you should remove the route you put in for NAT usage from the realservers. What that lot does is puts the VIP on the director's live interface and sets up the ipvs table, then you put the VIP on the realservers' loopback adapters and ensure that the realservers don't send ARP responses for that address. Hopefully you'll then see a fully-working LVS.

It works! With a working config in hand, I looked into getting it working with pulse. I compared the output of 'ipvsadm -L' after entering the literal commands you gave me, with the output having started pulse with my afore-pasted config file; there's a fairly substantive difference, but I'm not sure how _important_ it actually is. Namely: Graeme's working config: Prot LocalAddress:Port Scheduler Flags TCP cluster-test6.NebrWesleyan.e rr [...snip...] My non-working config: Prot LocalAddress:Port Scheduler Flags FWM 100 wlc That pretty well explains why it wasn't working: my config had 'fwmark=100' in the config, left over from the sample config I cannibalized, although I wasn't using (and wasn't planning on using) firewall marks. I removed that line, and suddenly a) 'ipvsadm -L' outputs matched; and b) the balancer worked with the pulse service. Woot! Thanks for everyone's help on this!

Actually, this was incorrect: Moving to a freshly compiled 2.6.28.7 resolved the issue *only when combined with the source routing configuration previously described*. Without source routing used to shepherd demasqueraded packets to eth1 (with a different, appropriate gateway), they still were leaving eth0 and being discarded by the local router. _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-request@LinuxVirtualServer.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users From lvs-users-bounces+archiver=linux-vs.org@linuxvirtualserver.org Thu Mar 26 16:29:58 2009 Return-Path: X-Original-To: archiver@linux-vs.org Delivered-To: archiver@dragon.linux-vs.org Received: from localhost (localhost.localdomain [127.0.0.1]) by dragon.linux-vs.org (Postfix) with ESMTP id 713C125C009 for ; Thu, 26 Mar 2009 16:29:58 +0800 (CST) Received: from dragon.linux-vs.org ([127.0.0.1]) by localhost (dragon.linux-vs.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 14540-04 for ; Thu, 26 Mar 2009 16:29:58 +0800 (CST) Received: from boom.graemef.net (boom.graemef.net [82.113.154.29]) by dragon.linux-vs.org (Postfix) with ESMTP id B097425C008 for ; Thu, 26 Mar 2009 16:29:56 +0800 (CST) Received: from localhost ([127.0.0.1] helo=boom.graemef.net) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1Lmkv9-0005XC-6c; Thu, 26 Mar 2009 08:26:39 +0000 Received: from adam.pmcipa.com ([71.9.23.14]) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1Lmkuz-0005Wy-Kp for lvs-users@linuxvirtualserver.org; Thu, 26 Mar 2009 08:26:36 +0000 Received: from ipa-vault.nvipa.com (fw1-dmz.pmcipa.com [71.9.23.9]) by adam.pmcipa.com (Postfix) with ESMTP id D22E64B0386 for ; Thu, 26 Mar 2009 01:27:08 -0700 (PDT) Received: from mail pickup service by ipa-vault.nvipa.com with Microsoft SMTPSVC; Thu, 26 Mar 2009 01:26:24 -0700 From: "Robinson, Eric" Importance: normal Priority: normal Content-Class: urn:content-classes:message MIME-Version: 1.0 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1933 Date: Thu, 26 Mar 2009 01:26:21 -0700 Message-ID: <768FEA3F936926468F594E3CA7741FE801631E44@ipa-vault.nvipa.com> X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: Why do Weights Change by Themselves? thread-index: AcmsZzjUhNVoiV4pS6KpK9oRO4uCRQBg+rzA To: "LinuxVirtualServer.org users mailing list."

I've observed on many occasions that weights sometimes seem to change spontaneously. For example, I have three Windows terminal servers as follows: TCP 192.168.5.100:3389 wlc -> 192.168.10.35:3389 Masq 20 19 0 -> 192.168.15.84:3389 Masq 40 51 0 -> 192.168.15.83:3389 Masq 40 52 0 The server at 192.168.10.35 is new and still in testing. I want it to handle less load than the othes, so I set its weight lower. But then I come back a few hours later and I find it looking something like this: TCP 192.168.5.100:3389 wlc -> 192.168.10.35:3389 Masq 1 41 0 -> 192.168.15.84:3389 Masq 1 40 1 -> 192.168.15.83:3389 Masq 1 41 0 Can anyone suggest a reason why these weights would change by themselves? -- Eric Robinson Disclaimer - March 26, 2009 This email and any files transmitted with it are confidential and intended solely for LinuxVirtualServer.org users mailing list..

Actually it's better this way, than to have them handled as a heartbeat resource. Let's call your setup box1 and box2 and on them run master1 + slave1 and master2 + slave2. Now master1 sends its updates to slave2 and master2 to slave1. If box1 is active, master2 will send (close to) nothing to slave1. I always set a different sync id on both master-slave connections, like this: box1 $ ipvsadm --start-daemon master --sync-id 50 box1 $ ipvsadm --start-daemon backup --sync-id 51 box2 $ ipvsadm --start-daemon master --sync-id 51 box2 $ ipvsadm --start-daemon backup --sync-id 50 But i'm not sure if that's necessary. It works though :) regards, Sebastian _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-request@LinuxVirtualServer.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users From lvs-users-bounces+archiver=linux-vs.org@linuxvirtualserver.org Fri Mar 27 01:21:48 2009 Return-Path: X-Original-To: archiver@linux-vs.org Delivered-To: archiver@dragon.linux-vs.org Received: from localhost (localhost.localdomain [127.0.0.1]) by dragon.linux-vs.org (Postfix) with ESMTP id 4481425C00A for ; Fri, 27 Mar 2009 01:21:48 +0800 (CST) Received: from dragon.linux-vs.org ([127.0.0.1]) by localhost (dragon.linux-vs.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 23881-07 for ; Fri, 27 Mar 2009 01:21:46 +0800 (CST) Received: from boom.graemef.net (boom.graemef.net [82.113.154.29]) by dragon.linux-vs.org (Postfix) with ESMTP id 1E56325C008 for ; Fri, 27 Mar 2009 01:21:44 +0800 (CST) Received: from localhost ([127.0.0.1] helo=boom.graemef.net) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LmtEl-0000vc-P7; Thu, 26 Mar 2009 17:19:28 +0000 Received: from adam.pmcipa.com ([71.9.23.14]) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LmtEj-0000vS-0z for lvs-users@linuxvirtualserver.org; Thu, 26 Mar 2009 17:19:25 +0000 Received: from ipa-vault.nvipa.com (fw1-dmz.pmcipa.com [71.9.23.9]) by adam.pmcipa.com (Postfix) with ESMTP id 16D364B0382 for ; Thu, 26 Mar 2009 10:20:07 -0700 (PDT) Received: from mail pickup service by ipa-vault.nvipa.com with Microsoft SMTPSVC; Thu, 26 Mar 2009 10:19:22 -0700 From: "Robinson, Eric" Importance: normal Priority: normal Content-Class: urn:content-classes:message MIME-Version: 1.0 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1933 Date: Thu, 26 Mar 2009 10:19:21 -0700 Message-ID: <768FEA3F936926468F594E3CA7741FE801631EAB@ipa-vault.nvipa.com> X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: [lvs-users] Why do Weights Change by Themselves? thread-index: AcmuCTZPLIjWk3JRSFulsOC+kqwxBQALY3wg To: "LinuxVirtualServer.org users mailing list."

I'm unable to find a solution browsing around, so I'm asking for some hints here. Basically, the scenario is the following: 5 servers (RIP), balanced with ipvs on linux 2.6.23, DR is used. All works just fine, but if for some reasons the real servers freezes and need reboot, ipvs keeps as "alive" all the connections so the balancing is not correctly done. say, after reboot a couple (out of five) of servers shows with ipvsadm -L more than 1000 connections (and all of those are fake, as the Rservers have been rebooted) and ipvs doesn't pass any new connection until the count lowers enough and only 3 servers are actually working. To fix this, I've tried to remove from ipvs real servers, virtual IP, I've also zeroed the tables but no success: when I reconfigure it all the RIP shows that all the connections are still there. The situation improves only after the connection timeout expires (usually 8 hours). If I lower this timeout, only new connection expires in a shorter time, so this is not a good solution. We need to keep high timeouts for several reasons (say, databases). Is there any way to clear this counter (syscalls, proc, whatever) so I can recover a correct behaviour of the balancer without booting the machine? I can figure out that it's a situation that ipvs can't handle automtically, but a way to clear tables should be useful. If course I'm available for further details. Many thanks in advance for any answer. _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - lvs-users@LinuxVirtualServer.org Send requests to lvs-users-request@LinuxVirtualServer.org or go to http://lists.graemef.net/mailman/listinfo/lvs-users From lvs-users-bounces+archiver=linux-vs.org@linuxvirtualserver.org Tue Mar 31 22:05:18 2009 Return-Path: X-Original-To: archiver@linux-vs.org Delivered-To: archiver@dragon.linux-vs.org Received: from localhost (localhost.localdomain [127.0.0.1]) by dragon.linux-vs.org (Postfix) with ESMTP id 0D2D425C006 for ; Tue, 31 Mar 2009 22:05:18 +0800 (CST) Received: from dragon.linux-vs.org ([127.0.0.1]) by localhost (dragon.linux-vs.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 05073-03 for ; Tue, 31 Mar 2009 22:05:12 +0800 (CST) Received: from boom.graemef.net (boom.graemef.net [82.113.154.29]) by dragon.linux-vs.org (Postfix) with ESMTP id 2DA6525C003 for ; Tue, 31 Mar 2009 22:05:10 +0800 (CST) Received: from localhost ([127.0.0.1] helo=boom.graemef.net) by boom.graemef.net with esmtp (Exim 4.69) (envelope-from ) id 1LoeYt-0006gl-Hx; Tue, 31 Mar 2009 15:03:31 +0100 Received: from smtp165.iad.emailsrvr.com ([207.97.245.165]) by boom.graemef.net with esmtps (TLSv1:AES256-SHA:256) (Exim 4.69) (envelope-from ) id 1LoeYr-0006gc-BS for lvs-users@linuxvirtualserver.org; Tue, 31 Mar 2009 15:03:29 +0100 Received: from relay6.relay.iad.emailsrvr.com (localhost [127.0.0.1]) by relay6.relay.iad.emailsrvr.com (SMTP Server) with ESMTP id 8FE997B9D65 for ; Tue, 31 Mar 2009 10:03:26 -0400 (EDT) Received: from webmail14.webmail.iad.mlsrvr.com (webmail14.webmail.iad.mlsrvr.com [192.168.1.37]) by relay6.relay.iad.emailsrvr.com (SMTP Server) with ESMTP id 8B1237B9A6A for ; Tue, 31 Mar 2009 10:03:26 -0400 (EDT) Received: from mailtrust.com (localhost [127.0.0.1]) by webmail14.webmail.iad.mlsrvr.com (Postfix) with ESMTP id F4018518021; Tue, 31 Mar 2009 10:03:25 -0400 (EDT) Received: by beta.mailtrust.com (Authenticated sender: jason.faulkner@mailtrust.com, from: jason.faulkner@mailtrust.com) with HTTP; Tue, 31 Mar 2009 10:03:25 -0400 (EDT) Date: Tue, 31 Mar 2009 10:03:25 -0400 (EDT) From: jason.faulkner@mailtrust.com To: "LinuxVirtualServer.org users mailing list."

Health checking is all external to ipvs. Since in LVS-DR the director doesn't see the returning packets, it has to guess when connections expire, and you've set a long timeout.
