Hi,
we have recently upgraded our ovirt environment from 4.1.6 to 4.1.9 and then to
4.2.5.
I don't know exactly when this issue was happened the first time, because on
the affected DCs, we haven't created new VMs for some time ago.
To our setup:
We have several DCs configured and only the former default one has quota
enabled.
We have separate templates for each DC and they haven't been cloned or anything
else from a template in default DC
When I now create a VM on DC from a template (disks are cloned), where quota is
not enabled, the new disks are getting quotas assigned, which are not available
in that DC!
The template disks all have the correct quota ID assigned!
Example from engine DB:
select * from image_storage_domain_map where storage_domain_id =
'73caedd0-6ef3-46e0-a705-fe268f04f9cc';
->

As you see, the disk a50b46ce-e350-40a4-8f00-968529777446 was created some
minutes ago, but it has a different default quota ID assigned as the other
disks above.
58ab004a-0315-00d0-02b8-00000000011d instead of
58ab004a-009a-00ea-031c-000000000182
select * from quota;
id | storage_pool_id |
quota_name | description | _create_date |
_update_date | threshold_cluster_percent
age | threshold_storage_percentage | grace_cluster_percentage |
grace_storage_percentage | is_default

As you see here, both quota IDs are default IDs and therefore can't be on the
same DC or storage domain.
As soon I enable quota on that DC, new disks created by VM creation via
template, will get the correct quota ID.
The problem with wrong IDs is, that you can't edit the disks anymore!
I can repeat that error every time and I can give all the information you need
to debug this. Pleas inform me, what data do you need...
Best Regards
Florian
