We can see a lot of related errors in the engine log but we are unable to correlate to the vdsm log. Do you have more hosts? If yes, please attach their logs as well. And just to be sure you were attempting to perform cold merge?

You can get my logs from:

They were a little to big to attach to this e-mail. Would like to know if this is the similar bug that Richard indicated is a possibility.

Hi, i have the same problem with gluster. this is a bug that i opened https://bugzilla.redhat.com/show_bug.cgi?id=1461029 . In the bug i used single disk vm but i start to notice the problem with multiple disk vm.

We are running a fresh install of oVIRT 4.1.3, using ISCSI, the VM in question has multiple Disks (4 to be exact). It snapshotted OK while on iSCSI however when I went to delete the single snapshot that existed it went into Locked state and never came back. The deletion has been going for well over an hour, and I am not convinced since the snapshot is less than 12 hours old that it’s really doing anything.

I have seen that doing some Googling indicates there might be some known issues with iSCSI/Block Storage/Multiple Disk Snapshot issues.

In the logs on the engine it shows:

This is what I seen on the SPM when I grep’d the Snapshot ID.
