Description Kevin Alon Goldblatt 2017-06-22 16:29:35 UTC

Description of problem:
Snapshot remains locked after failed live merge due to restart of vdsm

Version-Release number of selected component (if applicable):

Verified with the following code:
-------------------------------------------------------------
ovirt-engine-4.1.3.4-0.1.el7.noarch
rhevm-4.1.3.4-0.1.el7.noarch
vdsm-4.19.19-1.el7ev.x86_64


How reproducible:
Every time

Verified with the the following scenario:
------------------------------------------------------------
1. Create VM_14 with 5 disks , thin and preallocated, block and nfs
2. Create 3 snapshots, sna1, sna2, sna3
3. Start the snapshot vm22
4. Delete sna2 and a few seconds later restart the vdsm on the host . The delete fails of the snapshot fails and the snapshot sna2 remains in a locked state



Actual results:
The delete fails of the snapshot fails and the snapshot sna2 remains in a locked state


Expected results:
When the vdsm comes up again the snapshot should be in a normal state and allow a retry of the delete
