I'm following quick start guide and have a ceph cluster with three nodes.
When I try to map image to block device my command hangs. This seems like a
kernel hang as the only way I was able to get out is via a hard reset of
the image. The following is my configuration. Any help is greatly
appreciated.
command on the ceph-client node (that hangs):
$ sudo rbd map foo1 --pool rbd --name client.admin
*ceph-client node info:*
$ rbd info foo1
rbd image 'foo1':
size 4096 MB in 1024 objects
order 22 (4096 kB objects)
block_name_prefix: rb.0.1050.74b0dc51
