[ClusterLabs] Issue in starting Pacemaker Virtual IP in RHEL 7

[Somanath Jeeva]

Hi

I am using a two node pacemaker cluster with teaming enabled. The cluster has

1.       Two team interfaces with different subents.

2.       The team1 has a NFS VIP plumbed to it.

3.       The VirtualIP from pacemaker is configured to plumb to team0(Corosync ring number is 0)

In this case  the corosync takes the NFS IP as its ring address and checks the same in the corosync.conf. Since conf file has team0 hostname the corosync start fails.

Outputs:


$ip a output:
