Description Ribu Tho 2017-04-13 07:02:30 UTC 
Description of problem:

A snapshot job is selected to be deleted from RHV GUI . It errors on the host end and then completes . The completion never reaches engine and is lost in transmission for which snapshot still shows up . The 2nd issue for snapshot deletion causes stale entries and reports errors as such in engine event logs

Message: Failed to delete snapshot '<UNKNOWN>' for VM 'redhatguest'.
 

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

ovirt-engine-4.0.3-0.1.el7ev.noarch
vdsm-4.18.11-1.el7ev.x86_64

How reproducible:


Steps to Reproduce:

1. Create a snapshot 
2. Delete the  snapshot
3. host errors 1st time for "libvirtError: block copy still active: disk 'vda' not ready for pivot yet"
4. Operation completes and pivots on host end .
5. Engine fails to get this info and snapshot still shows up.
 
Actual results:

- The snapshot doesn't complete.
- Requires to run it again 
- Causes stale entries in the command_entities table that keeps retrying the snapshot removal job.

Expected results:

- Engine waits for the process to complete and marks the snapshot to be complete.
