[Gluster-users] Strange - Missing hostname-trigger_ip-1 resources

[ML Wong]

Thanks so much for your promptly response, Soumya.
That helps clearing out one of my questions. I am trying to figure out why
NFS service did not failover/pick-up the NFS clients last time when one of
our cluster-nodes failed.

Though i could see, in corosync.log, a notify got sent to the cluster the
failed node, the election, and the IP failover process seems to all be
finished with in around minute. However, after the IP failover to the
destinated node, i tried to do a "showmount -e localhost" - the command got
hung. But, i still see ganesha-nfsd is running in the host. To your
expertise, if i understand the process correctly, given that i keep all the
default timeout/interval settings for nfs-mon, nfs-grace, the entire IP
failover, and NFS service failover process should be completed within 2
minutes. Am i correct?

Your help is again appreciated.
