<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">We have a 6 nodes gluster running ubuntu on xfs sharing gluster volumes over NFS been running fine for 3 months.<br>
We restarted glusterfs-server on one of the node and all NFS clients start getting the " lockd: server not responding, timed out" on /var/log/messages<br>
<br>
We are still able to read write but seems like process that require a persistent file lock failed like database exports.<br>
<br>
We have an interim fix to remount the NFS with nolock option but need to know why that is necessary all in a sudden after a service glusterfs-server restart on one of the gluster node<br>
<br>
Thanks<br>
