ceph.conf is still the right way to set many configuration options. The
only things it is not recommended for are
- enumerating which daemons exist
- configuring data, journal, and keyring paths
In both cases, the preferred method is to enumerate OSDs, Monitors, etc in
/var/lib/ceph/{osd,mon,mds}/ directories. The locations can be indicated
with symlinks. This makes it easy to find ceph data on any node,
regardless of which filesystem is being used. The new style ceph-disk
utilities which do the OSD partitioning and fs creation steps rely on
this.
