Hi
I have some problems with heartbeat/lvs load balancing setup.
I'm trying to recognize what is really happening, as I'm in need to reconfigure
this setup. It is more heartbeat problem, but maybe somebody can help.
At first it looks like simple setup with 2 lamp servers serving site, and 2
load balancers, in active and standby/failover. lvs is happily directing
traffic
to lamp nodes, at least looking on ipvsadm output :
ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 123.123.123.244:443 rr persistent 600
-> 192.168.2.104:443 Route 1 12 16
-> 192.168.2.103:443 Route 1 4 0
TCP 123.123.123.244:80 rr persistent 600
-> 192.168.2.104:80 Route 1 3 24
-> 192.168.2.103:80 Route 1 2 10
But, my problem is that I'm expecting 123.123.123.244 IP, as a VIP, to be
present on one of load balancers, where heartbeat takes care of moving it in
case of failure. It is not. Both load balancers have eth0 interface with one
IP, eth1 with one IP, and loopback. Any ideas what I could use to investigate
this ?? Any tools to check heartbeat resources/setup or so ?? For now I can
only see that tcpdump shows traffic for 123.123.123.244 going through LB-2,
which is active load balancer. But how it is doing it, that is a mystery for
me. There could be a hint in logs, as it contains a line about promiscous
mode, but still can't see how IP can live on interface without actualy being
on that interface.
My config files below :
haresource:
LB-2 \
ldirectord::ldirectord.cf \
LVSSyncDaemonSwap::master \
IPaddr2::123.123.123.244/28/eth0/123.123.123.255
ha.cf:
logfacility local0
bcast eth0 # Linux
mcast eth0 225.0.0.1 694 1 0
auto_failback off
node LB-1
node LB-2
respawn hacluster /usr/lib/heartbeat/ipfail
apiauth ipfail gid=haclient uid=hacluster
