Hi all,

Responding to an old thread - but I'm having an issue with this. I can't remove the disk from a VM, without deleting a snapshot. Since deleting contents on my storage domain will crash it (long story..), I need to find a way to remove it from ovirt inventory without deleting the image files on disk.

- Can't delete the VM and uncheck "Remove disks", due to snapshots present;
- Can't delete the disk without permanently deleting it, due to snapshots present;

Are there any other options? What will happen if I put the storage domain in maintenance and destroy the entire storage domain? Is that even possible when VM's have disks associated to it that live on this storage domain?

Yes, when you do that the disk will remain "floating" (you'll be able to see it under the
Disks tab) and you'll be able to attach it to another vm later on.
