Florent,
I had similar issues, even when using ceph-disk. I've fixed it by making
sure the part-UUID of the journal partition is the only thing in the file
/var/lib/ceph/osd/{cluster}-{OSD#}/journal_uuid and made sure that the
/var/lib/ceph/osd/{cluster}-{OSD#}/journal was a symlink to the correct
part-uuid partition.
Ceph-disk list should map the journal and the data disks after that.
