Betreff: Re: [ovirt-users] New disks cloned from template get wrong quota-id, when quota is disabled on DC

Hi Florian,

This is definitely a bug. Can you please open a new ticket in Bugzilla?

https://bugzilla.redhat.com/enter_bug.cgi?product=ovirt-engine

Set 'oVirt team' to 'SLA'.

We don't need any more info for now, the info in the email is sufficient.

If it is not possible to edit the disks, the only workaround is to modify the DB directly:

UPDATE image_storage_domain_map

SET quota_id = quota.id

FROM storage_domains

JOIN quota ON storage_domains.storage_pool_id = quota.storage_pool_id

WHERE storage_domains.id = image_storage_domain_map.storage_domain_id

AND quota.is_default = true

AND image_storage_domain_map.image_id = '{ID_OF_THE_IMAGE}';

Best Regards,

Andrej

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
--------------------------------------+--------------------------------------+------------+-------------------------+-------------------------------+-------------------------------+--------------------------
----+------------------------------+--------------------------+--------------------------+------------
58ab004a-0315-00d0-02b8-00000000011d | 00000001-0001-0001-0001-000000000089 | Default | Default unlimited quota | 2017-02-20 14:42:18.967236+00 | |
80 | 80 | 20 | 20 | t

58ab004a-009a-00ea-031c-000000000182 | 5507b0a6-9170-4f42-90a7-80d22d4238c6 | Default | Default unlimited quota | 2017-02-20 14:42:18.967236+00 | |
80 | 80 | 20 | 20 | t

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
