Ceph

I was just doing a mkcephfs on my cluster and saw:

I just updated all my nodes and rebooted them, so /var/run/ceph was not present.

To me it seems that it's no problem that the admin_socket can't be created during a mkcephfs, but new users will probably think something went wrong.

I was thinking about having mkcephfs creating the directory, but it's also a option that the OSD skips the admin socket when only creating a new FS.
