Hi,
You can use the DeleteImage tool [1], but it's first recommended to backup
your engine.
To be on the safe side, here are some checks it's better to execute before
deleting:
- 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 found 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>;
[1]
DeleteImage tool:
SELECT DeleteImage('image-id');
DELETE
FROM images
WHERE image_guid = v_image_guid;
*Regards,*
*Shani Leviim*
