The partition type code for a data partition is 4FBD7E29-9D25-41B8-AFD0-062C0CEFF05D and the partition type code for a journal is 45B0969E-9B03-4F30-B4C6-5EC00CEFF106. That will fix your udev rules and probably make systemctl recognize them. What you need to do to remove the entries from your ceph.conf is to get them mounting in their default location. That is /var/lib/ceph/osd/ceph-#/ and make sure that the journal symlink in your osds points to the proper journal device. Usually try to do this by pointing it towards something that will persist on reboots like /dev/disk/by-uuid/{guid}.

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
