Fixed In Version:	org.ovirt.engine-root-3.4.3-4	Doc Type:	Bug Fix
Doc Text:	Previously, failing to attach an ISO domain caused the SPM to fail over and start a new SPM election attempt. This behavior caused a potential failover storm if the domain itself was corrupted, leaving the system without an SPM for a prolonged time. With this update, a failed attempt to attach an ISO domain to a datacenter will trigger an error message, but will not cause the SPM to fail over.	Story Points:	---

Comment 1 Elad 2014-11-17 07:22:30 UTC

A failure to attach an ISO domain back to the DC does not couse SPM failover:

IrsOperationFailedNoFailoverException: IRSGenericException: IRSErrorException: Failed to AttachStorageDomainVDS, error = Cannot obtain lock


Verified using rhev3.4.4 av13.1
