HI, I've got LVS running using piranha/pulse/nanny on a couple of CentOS 5.4 boxes.
Generally, everything is working just fine. However, I am experiencing apparently random failovers. I've included my lvs.cf at the end of this message. Now, as I understand it, the floating IP should stay on the primary server (admin address: 192.168.55.3) unless it goes away, in which case it should transfer to the backup (admin address: 192.168.53.4). What I'm seeing is that traffic appears to switch between devices for no apparent reason. If I stop the pulse daemon on the backup, the services switch to the primary server. But when I restart pulse on the backup, the services switch back to the backup server - sometimes! Has anyone else seen anything like this? Anyone got an explanation?
