I haven't set up the mgr service yet, but your daemon folder is missing
it's keyring file (/var/lib/ceph/mgr/ceph-0/keyring). It's exactly what the
error message says. When you set it up did you run a command pile ceph auth
add? If you did, then you just need to ask the cluster what the auth key is
and put it into that keyring file. You can look at the keyring for a month
to see what format it's expecting.
