Lots of "domain in problem" warnings

Thursday, 7 April 2016

Hi,

Lately we're having a lot of events like these:

clearing the domain recovery timer.

Up until now it's been only one domain that I see with this warning, 
this doesn't look good nevertheless. Not sure if related, but I can't 
find a disk with this UUID. How can I start debugging?

This is oVirt 3.6.4.1-1, and using an iSCSI-based storage backend.

Thanks.
