Hello,<br>
<br>
We have a small oVirt deplopyment, with 2 INTEL CPUs and 1 AMD,
therefor we defined 2 clusters.<br>
One of the Intel machines is running the management as well (We
called this SOL).<br>
This deployment is connected to a NAS through NFS shares.<br>
<br>
Suddenly (no more than 2 days) SOL is reported as "Non operational"
and in the Action Items is saying "<img class="gwt-Image"
onload='this.__gwtLastUnhandledEvent="load";'
src="cid:part1.08080605.07050106@matrixrom.com" style="width:
14px; height: 12px; background: transparent

no-repeat scroll 0px 0px; display: inline;" border="0">
<div>
<div style="display: inline;" class="gwt-Label">Host failed to
attach one of the Storage Domains attached to it."<br>
All other machines seems to be fine.<br>
<br>
In the past we encountered similar errors after (accidental)
reboot of the hosts, but now it is not the case:<br>
[root@sol ~]# uptime<br>
08:10:48 up 9 days, 15:48, 1 user, load average: 0.08, 0.05,
0.12<br>
<br>
The "funny" is that the virtual machines already started on SOL
are still running without any problems.<br>
<br>
I am not sure what logs to check.<br>
<br>
In /var/log/vdsm/vdsm.log we have this error, but I do not think
it is relevant:<br>
