Access the admin socket
Each Ceph daemon provides an admin socket that bypasses the MONs.
To access the admin socket, enter the daemon container on the host:
Example
[ceph: root@host01 /]# cephadm enter --name cephfs.hostname.ppdhsz
[ceph: root@mon1 /]# ceph --admin-daemon /var/run/ceph/ceph-cephfs.hostname.ppdhsz.asok config show
