Hi, I accidentally terminated an instance in openstack that was running a system upgrade. It's boot volume was a cinder volume backed by ceph cache tier pool.
Now i can not delete the volume neither from cinder of directly from ceph. If i try to delete it from cinder i get "rbd volume busy. Try again in 30 sec". If i try to delete it with rbd rm i get "Unable to delete. Volume still has watchers". I can delete the cinder volume manually from db, but i get stuck with the rbd volume that is present on the cache tier pool and cold-storage pool. Is there a way to remove the watchers from the image or force delete it with watchers active? Thank you!
