Hi,

I think we should treat each problem separately:

Can you run that SQL query on your engine and see the output?

SELECT *
     FROM images_storage_domain_view images_storage_domain_view
     WHERE image_group_id = '55893adf-1e56-4346-8070-4b3e660dd44d';

and same for 825765ba-b132-4b36-8cb9-8ecd2c7b597a.

Let's first verify the engine and vdsm are synced,

According to the vdsm-tool dump-volume-chains,

the disk you've mentioned seems to be legal:

   image:    a0f9a434-7837-4ec6-8017-c9698ed5cd01

             - 64ac336f-25d8-43d0-aeb8-7fb77bf6ef97
               status: OK, voltype: LEAF, format: RAW, legality: LEGAL, type: PREALLOCATED, capacity: 214748364800, truesize: 214748364800

Please share the output of the SQL query for this image as well (a0f9a434-7837-4ec6-8017-c9698ed5cd01)

Also, can you please share a screenshot of the snapshot's deletion and the illegal images?

Regards,

Shani Leviim

Hi,

It's very strange because in the engine UI i have only one disk in illegal status.

But i have a problem with another VM that have all the disk OK the storage migration begins, takes the snap shot then fails and the snapshot is deleted.

the size of the vm with the disk in illega is 200Gb the id of the disk is  a0f9a434-7837-4ec6-8017-c9698ed5cd01

Hi Massimo,

As shown on the output, you currently have 2 illeagal images:

   image:    55893adf-1e56-4346-8070-4b3e660dd44d

Can you try removing them from the engine UI?

Hi Shani

I run the command on the host owner of the SPM it's correct ?

This is the output:

[root@ovirthpr01 ~]# vdsm-tool dump-volume-chains eb483eb3-a9ce-4867-9ce8-96a0ca171042

Hi Massimo,

In order to locate the illegal image, you can run this command on the host:

vdsm-tool dump-volume-chains <sd_id>

It's also recommended to verify that the engine and vdsm are synced about that image, once you've find it, by running this command on the engine:
SELECT *
     FROM images_storage_domain_view images_storage_domain_view
     WHERE image_group_id = <image_group_id>;

Than, you can try removing it from the engine.

(and if it doesn't work - you can delete it from the DB)
