Live Storage Migration failed in VmReplicateDiskFinishVDSCommand

Solution In Progress - Updated -

Issue

  • Live Storage Migration failed in VmReplicateDiskFinishVDSCommand due to block job not complete.

  • Volumes were left on the target storage domain.

  • The block copy job was not terminated, and so both active volumes were still mirrored.

  • A subsequent Live Merge (snapshot deletion) failed, because a block job was still active, leaving a volume marked as illegal.
