Hi,
My ceph cluster include 5 OSDs. 3 osds are installed in the host
'strony-tc' and 2 are in the host 'strony-pc'. Recently, both of hosts
were rebooted due to power cycles. After all of disks are mounted again,
the ceph-osd are in the 'down' status. I tried cmd, "sudo start ceph-osd
id=x', to start the OSDs. But they are not started well with the error
below reported in the 'dmesg' output. Any suggestions about how to make
the OSDs started well? Any comments are appreciated.

Thanks,
Strony
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
