Ceph user and keyring

When cephx is enabled, you must specify a user name or ID and a path to the keyring containing the corresponding key for the user.

You might also add the CEPH_ARGS environment variable to avoid re-entry of the following parameters:

Syntax

rbd --id USER_ID --keyring=/path/to/secret [commands]
rbd --name USERNAME --keyring=/path/to/secret [commands]

Example

[root@rbd-client ~]# rbd --id admin --keyring=/etc/ceph/ceph.keyring [commands]
[root@rbd-client ~]# rbd --name client.admin --keyring=/etc/ceph/ceph.keyring [commands]
