Description Gordon Watson 2019-07-16 17:55:24 UTC

Description of problem:

Snapshot creation seemingly completed successfully, yet the snapshot remained 'LOCKED'. 

This VM consisted of two disks, each with three volumes, prior to the snapshot creation. The new volume for both disks was then successfully created and linked to each volume chain, marked as LEAF and set as the writable volume by 'qemu-kvm'.

All volume chains (d/b, volume metadata, XML, qcow headers) reflected the newly-added volumes correctly.

There were no tasks, jobs, steps or command entities in the d/b by the time it was captured.

It looks like the snapshot creation was successful, other than the snapshot (snapshots table entry) being unlocked.

Comment 8 Benny Zlotnik 2019-07-24 08:23:23 UTC

Yep, reproduced successfully

Steps to reproduce for QE, similar to [1]
1. Place a sleep in /usr/lib/python2.7/site-packages/vdsm/API.py Volume#getInfo() for about 90 seconds
2. Reduce transaction timeout to 60 seconds (see [1] for instructions)
3. Create a live snapshot
