[Linux-cluster] Error while doing failover of cluster nodes - Rhel7.2 - Gfs2 over nfs

[Dawood Munavar S M]

Hello,

I have configured a Rhel 7.2 pacemaker cluster and created nfs resources
over gfs2 file system & Mounting of file system is successful on NFS client.

I started I/O on NFS client and when I failover one of the cluster, I see
the below message and the I/O terminates,

05/12/17 20:15:26 Thread:1 System call error:13 - Permission denied (error
in write completion)

05/12/17 20:15:26 Thread:1 Error:12 - I/O error during a write operation
(LBA:0x0507F000 reqSize:524288 retSize:0)

05/12/17 20:15:26 Thread:1 (Context 0) Exiting on critical error(s)!

Please let me know if this a cluster configuration issue or issue at the
disk layer.
