You can use the all_disks_for_vms view, instead of all_disks. Then add the vm_id and / or vm_names columns. For example: /usr/share/ovirt-engine/dbscripts/engine-psql.sh -c "select disk_id,image_guid,disk_alias,disk_profile_name,vm_id,vm_names from all_disks_for_vms where disk_content_type='0' order by disk_alias" > /root/disk_ids-to_vms.txt -Patrick Hibbs On Sun, 2022-06-05 at 16:16 +0200, Gianluca Cecchi wrote: > > > On Mon, May 30, 2022 at 4:44 PM _isi _ wrote: > > Do you mean something like this ? > > > > /usr/share/ovirt-engine/dbscripts/engine-psql.sh -c "select > > disk_id,image_guid,disk_alias,disk_profile_name from all_disks > > where disk_content_type='0' order by disk_alias" > /root/disk_ids- > > to_vms.txt > > > > isi > > ___ > > Users mailing list -- users@ovirt.org > > To unsubscribe send an email to users-le...@ovirt.org > > Privacy Statement: https://www.ovirt.org/privacy-policy.html > > oVirt Code of Conduct: > > https://www.ovirt.org/community/about/community-guidelines/ > > List Archives: > > > https://lists.ovirt.org/archives/list/users@ovirt.org/message/3FBFDABUYYTMVWQGJWRKAXESO3S67JWO/ > > > > > partially, because in my case if I take a VM with VM ID 711e5dc6- > 04a1-42a4-b52c-96685bc19b1f > > It has 3 disks, one of which has the alias ostack-ceph1_Disk3 > > the query for this disk gives > select disk_id,image_guid,disk_alias,disk_profile_name from > all_disks where disk_content_type='0' order by disk_alias; > . . . > 1093ada3-65b2-407a-a6b8-fd9529f4a0db | ded7c7c7-477f-44e3-8ac5- > 8908bde6340c | ostack-ceph1_Disk3 | 2t_1 > > And I get under /2t_1 > > /2t_1/images/caa6fd69-e371-4476-89eb-cbbae82c2add/images > > # ll | grep 1093 > drwxr-xr-x. 2 vdsm kvm 4096 Apr 20 2021 1093ada3-65b2-407a-a6b8- > fd9529f4a0db > # > > # cd 1093ada3-65b2-407a-a6b8-fd9529f4a0db/ > # ll > total 156872396 > -rw-rw. 1 vdsm kvm 161061273600 Apr 30 2021 ded7c7c7-477f-44e3- > 8ac5-8908bde6340c > -rw-r--r--. 1 vdsm kvm 289 Apr 20 2021 ded7c7c7-477f-44e3- > 8ac5-8908bde6340c.meta > # > > but I miss the link between the id of the VM and the disk, that is > what I would like to get > > ___ > Users mailing list -- users@ovirt.org > To unsubscribe send an email to users-le...@ovirt.org > Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/users@ovirt.org/message/BJ5J4KNMMZ4PNWAYHAC36AW7T4W4ICZU/ ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/U5OKETQOCAVR3LS6VPUAZFV5VLNBF3KV/

Yes, I think the reserved default space.
In the meantime I selected a not important VM where I had a 100Gb data disk
(it was the only one of this type of disk size, so it was easy to find it
on filesystem) and executed
cat /dev/null > disk_file
so that I didn't have any logical inconsistency from oVirt point of view
and 100Gb of space immediately released.
Then I was able to activate the storage domain and delete the VM and go on
with further analysis on disk usage.
Anyway it would be useful to have a way to search through the engine
database to have an easier mapping between disk files and VMs.

Why is the size (1.8T) different from Used (1.7T) despite Use%=100%?
If this is because it's an ext4 filesystem, you can try reducing the
amount reserved to root ('tune2fs -m 1' or so). I think the fs should
be unmounted for this.

I don't believe severe damage can happen by doing this, but really have no idea.

Perhaps you can also temporarily move some VMs' disks to some other
local storage and symlink there - no idea what vdsm might do. I think
qemu will be happy, if it can access them (you might need to play with
permissions/selinux/etc).
I'd personally try any of the above on a test setup first.
