[Users] oVirt storage is down and doesn't come up

Fri Apr 12 12:29:06 EDT 2013

Hi,

For some reason, without doing anything, all the storage domains became
down and restarting VDSM or the entire machine do not bring it up.
I am not using lvm
The following errors appear several times in vdsm.log (full logs are
attached):
