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?
