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

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)
