to check if the issue is with the glusterfs client, we
mount the volume using NFS (NFS on the client talking to
gluster on the master), the issue doesn’t occur.
However, with the NFS client talking directly to _one_
of the gluster masters; this means that if that master
fails, it will not failover to the other gluster master
- we thus lose gluster HA if we go this route. </div>

If you are interested there are HA solutions available with NFS. It
depends on NFS solution which u are trying, if it is gluster
nfs(integrated nfs server with gluster) then use ctdb and for
NFS-Ganesha , we already have an integrated solution with
pacemaker/corosync<br>
<br>
Please update ur gluster version since it EOLed, you don't receive
any more update for that version.<br>
