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>;

Regards,
Shani Leviim
