Hi all,
I am trying to remove several rbd images from the cluster.
Unfortunately, that doesn't work:
$ rbd info foo
rbd image 'foo':
size 1024 GB in 262144 objects
order 22 (4096 kB objects)
block_name_prefix: rb.0.919443.238e1f29
format: 1
$ rbd rm foo
2015-07-29 10:25:01.438296 7f868d330760 -1 librbd: image has watchers -
not removing
Removing image: 0% complete...failed.
rbd: error: image still has watchers
This means the image is still open or the client using it crashed. Try
again after closing/unmapping it or waiting 30s for the crashed client
to timeout.
$ rados -p rbd listwatchers foo
error listing watchers rbd/foo: (2) No such file or directory
Well, that is quite frustrating. The image was mapped on one host, where
I was unmapping it. What do I have to do to get rid of it?
We are using ceph version 0.87.2
Regards,
Christian
