Hi all,

A colleague launched this morning a snapshot creation, there was no error message but he wasn't able to start the vm anymore, with this issue : VM PSI-SYB-DEV is down with error. Exit message: Unable to get volume size for domain a5be6cae-f0c8-452f-b7cd-70d0e5eed710 volume 109fac1e-c2e3-4ba6-9867-5d1c94d3a447..

I tried many things but nothing works: it is impossible to remove this disk, or copy it, or clone the vm :

Cannot detach Virtual Disk. The disk is already configured in a snapshot. In order to detach it, remove the disk's snapshots.

There is no snaphost listed into webui or api (so not snapshot id), while disk_snapshots exists into the associated storage domain.

So I tried to remove disks snapshot direvctly with API followind the DELETE method

DELETE /api/storagedomains/{storage_id}/disksnapshots/{image_id}

[Cannot remove Disk Snapshot. VM\'s Snapshot does not exist.]

In conclusion: vm_disks can't be removed because of the non existent associated vm's snapshot id.

I tried to remove vm_snapshots disks references directly into the postgres DB but I didn't find the correct table.

What can I do now?

Your precious help is welcome.
