You need to use the --id and --cluster options of the rbd command and
maintain a .conf file for each cluster.

/etc/ceph/clusterA.conf
/etc/ceph/clusterB.conf

/etc/ceph/clusterA.client.userA.keyring
/etc/ceph/clusterB.client.userB.keyring

now use the rbd commands as such:

rbd --id userA --cluster clusterA

This will cause the client to read the appropriate files (
/etc/ceph/clusterA.client.userA.keyring and  /etc/ceph/clusterA.conf)
The --id and --cluster translate to which file is read for config and
keyring
