I use a scripted installation of ceph without ceph-deploy, which works fine on
0.63. On 0.80 it fails to add the OSDs. In this scenario the local OSDs are all
listed in ceph.conf.
It runs:
mkcephfs --init-local-daemons osd -d blah
which creates the OSDs (as in they are there on the file system):
# ls /var/lib/ceph/osd/ceph-*
/var/lib/ceph/osd/ceph-0:
ceph_fsid current fsid journal keyring magic ready store_version
superblock whoami
/var/lib/ceph/osd/ceph-1:
ceph_fsid current fsid journal keyring magic ready store_version
superblock whoami
/var/lib/ceph/osd/ceph-2:
ceph_fsid current fsid journal keyring magic ready store_version
superblock whoami
/var/lib/ceph/osd/ceph-3:
ceph_fsid current fsid journal keyring magic ready store_version
superblock whoami
However I get:
# service ceph start
=== mon.a ===
Starting Ceph mon.a on extility-qa2-test...already running
=== osd.0 ===
Error ENOENT: osd.0 does not exist. create it before updating the crush map

--keyring=/var/lib/ceph/osd/ceph-0/keyring osd crush create-or-move -- 0 0.09
host=extility-qa2-test root=default'
and ceph status returns no osds:
root@extility-qa2-test:~# ceph status

pgmap v2: 768 pgs, 3 pools, 0 bytes data, 0 objects

I'm fully aware there is a newer way to do this, but I'd like this route to
work too if possible.
Is there some new magic I need to do to get ceph to recognise the osds? (again
without ceph-deploy)
