Hi All,
I have deleted the pool and created a fresh images pool. I am unable to delete
the existing image.

Hi All,
Any ideas ? As a temporary necessity , I have deleted the entire 'images' pool.
How to delete individual images ?
Thanks

How to delete the images ? Does restarting ceph services help ?
Thanks

Hi
Probably because you have snapshots mapped somewhere on a node or because you
have cloned some images from snapshot which are protected to deploy VMs.
This will prevent the deletion of the snapshots in both cases

Hi
rbd -p <poolname> rm <imagename>
e.g. rbd -p volumes rm volume-55abf0d4-01a7-41d0-9e7e-407ad0db213c
