<div class="moz-cite-prefix">I found that when I was exporting NFS
from gluster I had to be careful not to load the kernel nfs
modules (such as lockd) or things would get messed up. I think
that's happened to you.<br>
<br>
Is gluster lockd in use? Do this:<br>
<br>
<font face="Consolas">[root@fearless1 ~]# rpcinfo -p | grep 100021<br>
100021 4 tcp 38468 nlockmgr<br>
100021 1 udp 872 nlockmgr<br>
100021 1 tcp 874 nlockmgr<br>
[root@fearless1 ~]# ss -lp sport = :38468<br>
State Recv-Q Send-Q Local Address:Port Peer
Address:Port<br>
LISTEN 0 10
*:38468 *:*
users:(("glusterfs",28675,13))<br>
</font><br>
Yes it is!<br>
<br>
If not:<br>
* ensure no nfs mounts are on gluster servers<br>
* rmmod nfs<br>
* rmmod lockd<br>
* 'gluster volume volname start force' should ensure all the
daemons are up.<br>
