Yes, I confirm... if you are talking about the journal partitions of OSDs.
Another solution: via a udev rule, set "ceph" as owner of these partitions. In my case, all journal partitions have this kind of partname (gtp partition): "osd-$id-journal".
So I have defined this udev rule:
# cat /etc/udev/rules.d/90-ceph.rules
# Udev rule to have "ceph" owner of each "/dev/disk/by-partlabel/osd-*-journal"
# partition from GPT disks. Totally inspired from this file
# /lib/udev/rules.d/60-persistent-storage.rules
ENV{ID_PART_ENTRY_SCHEME}=="gpt", ENV{ID_PART_ENTRY_NAME}=="osd-?*-journal", OWNER="ceph"
For me, it works.
HTH.
