</div>We can see in /var/log/messages, that sanlock failed to write to<br>
the ids lockspace [1], which after 80 seconds [2], caused vdsm to loose<br>
its host id lease. In this case, sanlock kill vdsm [3], which die after 11<br>
retries [4]. Then vdsm is respawned again [5]. This is expected.<br>
<br>
We don't know why sanlock failed to write to the storage, but in [6] the<br>
kernel tell us that the nfs server is not responding. Since the nfs server<br>
is accessible from other machines, it means you have some issue with this host.<br>
<br>
Later the machine reboots [7], and nfs server is still not accessible. Then<br>
you have lot of WARN_ON call traces [8], that looks related to network code.<br>
<br>
We can see that you are not running most recent kernel [7]. We experienced various<br>
nfs issues during the 6.5 beta.<br>
<br>
I would try to get help from kernel folks about this.<br>
