Hi,

We're running oVirt 4.5. We have a template which we'd like to
get
rid
of, there are no VMs based on it. However, trying to remove it
oVirt

states that:

Cannot remove Template. The following Disk(s) are based on it:
(b54ee1cb-ed64-4db4-bd3d-eac8b22ea095) .

When opening the 'Disks' subtab in the template, it appears a
disk
(screenshot attached).

However, when opening the oVirt Storage->Disks option, I cannot
find
the
disk by the ID, not even ordering the ID column and trying to
find
it
visually.

Can anyone point to the problem and a possible
solution/workaround?

Can you share the output of the following DB queries:
1. select * from base_disks where
disk_id='b54ee1cb-ed64-4db4-bd3d-eac8b22ea095';


engine=# select * from base_disks where
disk_id='b54ee1cb-ed64-4db4-bd3d-eac8b22ea095';
disk_id | wipe_after_delete | propagate_errors | disk_alias |
disk_description | shareable | sgio | disk_storage_type |
cinder_volume_type | disk_content_type | backup | backup_mode

2. select * from images where
image_group_id='b54ee1cb-ed64-4db4-bd3d-eac8b22ea095';

I don't think I ever saw this situation of having an image that is not
correlated with a base_disk
I'd suggest to run another query:
select * from images where
parentid='987fcd68-d48e-4314-bb4e-363671d222be';

If it doesn't return any result, take a backup of the database (just
in case) and then remove the image from the database:
delete from images where
image_guid='987fcd68-d48e-4314-bb4e-363671d222be';

This should make it possible to remove the template.

Indeed, that did the trick.

Thanks.
