Hi Kaleb,
Setting up of the grace-period is not working in case of active/active setup. we have
tried setting up Grace_Period = 20; but it does not impact the problem.
Setup:
3 Node Ceph Cluster,
Node1: ceph(mon/mds/rgw/osd)
Node2: ceph(mon/mds/rgw/osd)+NFS(Active)
Node3: Ceph(only Mon)+NFS(Active)
Issues is :
I/O operations is not resuming after NFS Node is powered off.
if Node 2(refer above) is powered off, it remains stuck unless powered-on.
if Node3is powered off,it takes around 5 min to resume the I/O.

Yes i see the ganesha.log for entering and leaving NFS-GRACE?

in current state we are only using pcs cluster to failover IP resource, but in case of
active/passive - pcs property set stonith-enabled=false
any standard configuration for this ?
