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 Respectfully, *Wes Dillingham* wes@wesdillingham.com LinkedIn <http://www.linkedin.com/in/wesleydillingham> On Mon, Jun 26, 2023 at 9:15 AM garcetto <garcetto@gmail.com> wrote:

good afternoon, how can i config ceph.conf file on a generic rbd client to say to use two different ceph clusters to access different volumes on them?
