[Pacemaker] nfs4 cluster fail-over stops working once I introduce ipaddr2 resource

[Dennis Jacobfeuerborn]

Hi,
I'm still working on my NFSv4 cluster and things are working as 
expected...as long as I don't add an IPAddr2 resource.

The DRBD, filesystem and exportfs resources work fine and when I put the 
active node into standby everything fails over as expected.

Once I add a VIP as a IPAddr2 resource however I seem to get monitor 
problems with the p_exportfs_root resource.

I've attached the configuration, status and a log file.

The transition status is the status a moment after I take nfs1 
(192.168.100.41) offline. It looks like the stopping of p_ip_nfs does 
something to the p_exportfs_root resource although I have no idea what 
that could be.

The final status is the status after the cluster has settled. The 
fail-over finished but the failed action is still present and cannot be 
cleared with a "crm resource cleanup p_exportfs_root".

The log is the result of a "tail -f" on the corosync.log from the moment 
before I issued the "crm node standby nfs1" to when the cluster has settled.

Does anybody know what the issue could be here? At first I thought that 
using a VIP from the same network as the cluster nodes could be an issue 
but when I change this to use an IP in a different network 
192.168.101.43/24 the same thing happens.

The moment I remove p_ip_nfs from the configuration again fail-over back 
and forth works without a hitch.

Regards,
   Dennis
