[ovirt-users] Corrupted VM's

Tue Oct 6 13:00:52 UTC 2015

Hi Nir,

Thank you for coming back to me. I see in the ovirt-engine log the one VM
said it ran out of space, do you think perhaps the SAN itself was over
allocated somehow? Could this cause the issue shown in the logs?

In order to restore I had to delete some old VM's so this would have free'd
up lots of space and in doing so perhaps resolve the problem?

Just a thought really.

Thank you.

Regards.

Neil Wilson.
