The farm IP is configured in "eth0:1" and cluster is configured in "eth1:1"
interface. When node1 is restarted/powered off, the IP assgned to eth1:1
failovers to secondary node but the farm IP goes unreachable until zenlb
service is manually restarted in secondary node.
Has anyone tried this setup? Any idea how to fix this?
Thanks
