+----
+# scp <external cephserver>:/etc/ceph/cephfs.secret /root/cephfs.secret

+
+Then use the `pvesm` CLI tool to configure the external RBD storage, use the
+`--keyring` parameter, which needs to be a path to the secret file that you
+copied. For example:
+
+----
+# pvesm add cephfs <name> --monhost "10.1.1.20 10.1.1.21 10.1.1.22" --content backup --keyring /root/cephfs.secret
