Hello,
We have a small oVirt deplopyment, with 2 INTEL CPUs and 1 AMD, therefor
we defined 2 clusters.
One of the Intel machines is running the management as well (We called
this SOL).
This deployment is connected to a NAS through NFS shares.
Suddenly (no more than 2 days) SOL is reported as "Non operational" and
in the Action Items is saying "
Host failed to attach one of the Storage Domains attached to it."
All other machines seems to be fine.
In the past we encountered similar errors after (accidental) reboot of
the hosts, but now it is not the case:
[root@sol ~]# uptime
08:10:48 up 9 days, 15:48, 1 user, load average: 0.08, 0.05, 0.12
The "funny" is that the virtual machines already started on SOL are
still running without any problems.
I am not sure what logs to check.
In /var/log/vdsm/vdsm.log we have this error, but I do not think it is
relevant:
