Hi Bruno,

Can you please share the output of:

vdsm-tool dump-volume-chains <the-relevant-storage-domain-id>

Also, can you see those images on the 'images' table?

Regards,

Shani Leviim

Good morning, Shani

I'm not trying to deactivate any disk because the VM using it is working. I can't turn it off because I'm pretty sure if I do I won't be able to turn it on again, in fact the web interface is telling me that if I turn it off possibly it won't restart :(

For what I can check I have no information about any of the the snapshots I provided in the database

engine=# select * from snapshots where snapshot_id IN ('f649d9c1-563e-49d4-9fad-6bc94abc279b', '5734df23-de67-41a8-88a1-423cecfe7260', 'f649d9c1-563e-49d4-9fad-6bc94abc279b', '2929df28-eae8-4f27-afee-a984fe0b07e7', '4bd4360e-e0f4-4629-ab38-2f0d80d3ae0f', 'fbaff53b-30ce-4b20-8f10-80e70becb48c', 'c628386a-da6c-4a0d-ae7d-3e6ecda27d6d', 'e9ddaa5c-007d-49e6-8384-efefebb00aa6', '5b6db52a-bfe3-45f8-b7bb-d878c4e63cb4', '7efe2e7e-ca24-4b27-b512-b42795c79ea4');

Hi Bruno,

It seems that the disk you're trying to deactivate is in use ( Logical volume e655abce-c5e8-44f3-8d50-9fd76edf05cb/fa154782-0dbb-45b5-ba62-d6937259f097 in use).

Is there any task that uses that disk?

Also, did you try to verify the snapshot's creation date with the DB?

( select * from snapshots; )

Regards

Hello, 

We are experiencing some problems with some snapshots in illegal status generated with the python API. I think I'm not the only one, and that is not a relief but I hope someone can help about it. 

I'm a bit scared because, for what I see, the creation date in the engine for every snapshot is way different from the date when it was really created. The name of the snapshot is in the format backup_snapshot_YYYYMMDD-HHMMSS, but as you can see in the following examples, the stored date is totally random...

Size

Creation Date

Snapshot Description

Status

Disk Snapshot ID

For what I understand, there was a "Cannot deactivate logical volume" problem that I would thank very much if someone can help me about how to solve

Thanks again
