greetings.
I have somewhat of a similar problem
osd's that are just a single disk start on boot.
but osd's that are software raid md devices does not start automatically
on boot
in order to mount and start them i have to run
ceph-disk-activate /dev/md127p1
where /dev/md127p1 is the xfs partition for the osd.
good luck
Ronny Aasen
