Hi,
Need a help regarding rbd CLI commands hanging if the cluster is in
error state.
Somehow I ended up having my cluster in HEALTH_ERR by creating a pool
with huge PGnum whereas cluster has very less no of OSDs.
Now when I run the command `rbd ls` it simply hangs and does not come
out. It requires a ctrl+C to come back to command line.
What could be a workaround or solution to this?
Regards,
Shubhendu

RBD images are stored in RADOS, so if your RADOS cluster is not
accessible then your rbd operations will block until it is.
