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

Wed Apr 17 09:28:55 EDT 2013

Hi Limor,
1) Your log starts exactly after the vdsm restart. I need to see the full vdsm log from before the domains went down in order to understand the problem. Can you attach them?
2) can you send the printout of 'tree /rhev/data-center/' 
3) how many domains are attached to your DC, and what type are they(ISO, export,data) and (The DC is nfs right)?

Thanks,
Yeela
