Erekle, In the logs you provided I see:
IOError: [Errno 5] _handleRequests._checkForMail - Could not read mailbox: /rhev/data-center/6d52512e-1c02-4509-880a-bf57cbad4bdf/mastersd/dom_md/inbox and StorageDomainMasterError: Error validating master storage domain: ('MD read error',) which seems to be cause for vdsm being killed by sanlock which caused connection reset by peer. After vdsm restart storage looks good. @Nir can you take a look?
