Re: how to update old pre ceph-deploy osds to current systemd way?

We had to update the OS / kernel, chown all the data to ceph:ceph, and update the partition type codes on both the OSDs and journals. After this udev and systemd brought them up automatically.

Subject: how to update old pre ceph-deploy osds to current systemd way?
 
Hello,

i've some osds which were created under bobtail or argonaut (pre
ceph-deploy).

Those are not recognized as a ceph-osd@57.service . Also they have an
entry in the ceph.conf:

[osd.12]
        host=1336
        osd_data = /ceph/osd.$id/
        osd_journal = /dev/disk/by-partlabel/journal$id

Is there any way to migrate them?

Greets,
Stefan
