Hi,
We have an experimental LVS setup here...
Our director has multiple VIPs, 172.21.193.11 and 172.21.193.62 (running
on eth0:11 and eth0:62 respectively), it's real IP (eth0) is
172.21.193.101
We have two real servers, 172.21.193.103 and 172.21.193.104, each of
which has multiple virtual ethernet devices to correspond to the VIPs on
the director - 10.0.1.11/62 and 10.0.2.11/62 (eth0:11, eth0:62)
The .11 VIP is used for name based VirtualHosts in Apache, and .62 is an
IP based VirtualHost, which is also used for SSL
Our ipvsadm output is:
director1:~ # ipvsadm
IP Virtual Server version 0.9.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP director11:http wrr
-> cluster2default:http Masq 1 0 0
-> cluster1default:http Masq 4 0 0
TCP director62:http wrr
-> cluster262:http Masq 1 0 0
-> cluster162:http Masq 4 0 0
TCP director62:https wrr persistent 360
-> cluster262:https Masq 1 0 0
-> cluster162:https Masq 4 0 0
The problem we have is that we (apparently) randomly are unable to
connect to the services, sometimes entire services, sometimes specific
real-servers within a service, the most common problem is connecting to
172.21.193.62 when it is masq'd to 10.0.2.62
Legend for ipvsadm output:
director11 172.21.193.11
director62 172.21.193.62
cluster1default 10.0.1.11
cluster2default 10.0.2.11
cluster162 10.0.1.62
cluster262 10.0.2.62
Can anyone help?
