No, it’s not ok to remove it while live merge(apparently) is still ongoing I guess that’s a live merge bug?
Indeed, this is bug 1302215.
I wrote a sql script to help with cleanup in this scenario, which you can find attached to the bug along with a description of how to use it[1].
However, Rik, before trying that, would you be able to run the attached script [2] (or just the db query within) and forward the output to me? I'd like to make sure everything looks as it should before modifying the db directly.
I ran the following query on the engine database: select images.* from images join snapshots ON (images.vm_snapshot_id = snapshots.snapshot_id) join vm_static on (snapshots.vm_id = vm_static.vm_guid) where vm_static.vm_name = 'lena' and snapshots.description='before jessie upgrade'; The resulting output is: image_guid | creation_date | size | it_guid | parentid | images tatus | lastmodified | vm_snapshot_id | volume_type | volume_format | image_group_id | _create_da te | _update_date | active | volume_classification --------------------------------------+------------------------+-------------+--------------------------------------+--------------------------------------+------- ------+----------------------------+--------------------------------------+-------------+---------------+--------------------------------------+------------------- ------------+-------------------------------+--------+----------------------- 24d78600-22f4-44f7-987b-fbd866736249 | 2015-05-19 15:00:13+02 | 34359738368 | 00000000-0000-0000-0000-000000000000 | 00000000-0000-0000-0000-000000000000 | 4 | 2016-01-30 08:45:59.998+01 | 4b4930ed-b52d-47ec-8506-245b7f144102 | 1 | 5 | b2390535-744f-4c02-bdc8-5a897226554b | 2015-05-19 15:00:1 1.864425+02 | 2016-01-30 08:45:59.999422+01 | f | 1 (1 row) Regards, Rik

[2] Arguments are the ovirt db name, db user, and the name of the vm you were performing live merge on.

Hi,
I created a snapshot of a running VM prior to an OS upgrade. The OS upgrade has now been succesful and I would like to remove the snapshot. I've selected the snapshot in the UI and clicked Delete to start the task.
After a few minutes, the task has failed. When I click delete again on the same snapshot, the failed message is returned after a few seconds.
From browsing through the engine log (attached) it seems the snapshot
was correctly merged in the first try but something went wrong in the finalizing fase. On retries, the log indicates the snapshot/disk image no longer exists and the removal of the snapshot fails for this reason.
Is there any way to clean up this snapshot?
I can see the snapshot in the "Disk snapshot" tab of the storage. It has a status of "illegal". Is it OK to (try to) remove this snapshot? Will this impact the running VM and/or disk image?
