Now I use the following script to create key/value backended OSD, but

ceph osd create

mkdir /var/lib/ceph/osd/ceph-0
ceph osd crush add osd.0 1 root=default host=CVM-0-11
mkfs -t xfs -f /dev/hioa
mount /dev/hioa /var/lib/ceph/osd/ceph-0
ceph-osd --id 0 --mkkey --mkfs --osd-data /var/lib/ceph/osd/ceph-0
/etc/init.d/ceph start osd.0
Anything goes wrong?
Ahh - looking closer - you are missing a step to register the osd key
before trying to start it. E.g I do:
$ ceph auth add osd.${OSD_ID} osd 'allow *' mon 'allow profile osd' \
-i /var/lib/ceph/osd/ceph-${OSD_ID}/keyring
...which is why I save the OSD_ID when I do a create of the osd (It'll
be zero in most cases where you are doing this, but in case you want to
expand the script to create more osd this is the right way)!
Cheers
