I managed to delete it after running "rados -p cache-ssd listwatchers rbd_header.xxxx". It was one of the monitors that was watching and keeping the image busy. Any light on why did the monitor kept keeping the image busy? I would like to know!
Thanks!

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!
