Hi,

The ability to update a disk and its size was upgraded in 4.4
http://ovirt.github.io/ovirt-engine-api-model/4.4/#services/disk/methods/update

That way, you can edit floating disk parameters, such as extend its size, without attaching the disk to a VM.

On version 4.3, as already mentioned, the disk should be attached to the VM.

In your case, you can see the disk's size with the following request:

GET https://ovirt.domain.com/ovirt-engine/api/disks/f770c0d1-dd0d-40a8-a69a-a63d8db5c2cc

Is there some more info on the engine log?

Regards,

Shani Leviim
