I've just finished a double upgrade on my ceph (PVE-based) from hammer
to jewel and from jewel to luminous.
All went well, apart that... OSD does not restart automatically,
because permission troubles on the journal:

A little fast rewind: when i've setup the cluster i've used some 'old'
servers, using a couple of SSD disks as SO and as journal.
Because servers was old, i was forced to partition the boot disk in
DOS, not GPT mode.
While creating the OSD, i've received some warnings:
WARNING:ceph-disk:Journal /dev/sdaX was not prepared with ceph-disk.
Symlinking directly.
Looking at the cluster now, seems to me that osd init scripts try to
idetify journal based on GPT partition label/info, and clearly fail.
Not that if i do, on servers that hold OSD:
for l in $(readlink -f /var/lib/ceph/osd/ceph-*/journal); do chown
ceph: $l; done
OSD start flawlessy.
There's something i can do? Thanks.
