Hi David,

Can you share a screenshot of the error you're getting?

And how the snapshots are presented on the ui?

Regards,

hi

attempt to remove snapshot from UI results in an error

I looked the LV through the lvs and did't find active snapshot ID, only the base snapshot ID is present

ovirt in database see 2 snapshots, but i have only one base image on storage

so, i must remove the active snapshot ID from db not the base image Id ?

Hi David,

Sorry for the late reply.

the volume_dump returned 1 occurrence of that image, while the query returned 2 occurrences.

It seems that there's an image id with a description of 'Auto-generated for Live Storage Migration' which wasn't removed from the DB.

Can you try to remove it from the UI?

(If you claimed to remove it, try to remove it from the DB).

Hi David,

First, we need to compare the chain as it is seen by the engine and the host and see if there's a difference.

Can you please share the output of the following?

On the host:

vdsm-tool dump-volume-chains <sd_id>

On the engine:

SELECT *
     FROM images_storage_domain_view images_storage_domain_view
     WHERE image_group_id = <image_group_id>;
