This here tells me you have tried this more than once:

Or possibly deployed to a host that had left overs from another
cluster. There are many reasons why a monitor may not come up, you
could
try looking at the logs in the `dumbo007` box and look at
/var/log/ceph/* and `journalctl -xe` to find out what the unit file is
complaining about.
