Fixed In Version:	ovirt-engine-4.4.9.2	Doc Type:	Bug Fix
Doc Text:	Previously, the status of the operation (download VM disks) was changed to one of the final statuses (FINISHED_SUCCESS / FINISHED_FAILURE) before the disk locks were actually released. As a result, in some scenarios, the operation following this one failed with a Disk is locked error. In this release, the locks are released immediately before changing the command status to one of the final phases. AS a result, the operation that follows this one and uses the same disk will succeed.	Story Points:	---
