Hm. You are right. Seems ceph-osd uses id 0 in main.py.
I'll have a look in my dev cluster and see if it helps things.
/usr/lib/python2.7/dist-packages/ceph_disk/main.py
def check_journal_reqs(args):
_, _, allows_journal = command([
'ceph-osd', '--check-allows-journal',
'-i', '0',
'--log-file', '$run_dir/$cluster-osd-check.log',
'--cluster', args.cluster,
'--setuser', get_ceph_user(),
'--setgroup', get_ceph_group(),
])
_, _, wants_journal = command([
'ceph-osd', '--check-wants-journal',
'-i', '0',
'--log-file', '$run_dir/$cluster-osd-check.log',
'--cluster', args.cluster,
'--setuser', get_ceph_user(),
'--setgroup', get_ceph_group(),
])
_, _, needs_journal = command([
'ceph-osd', '--check-needs-journal',
'-i', '0',
'--log-file', '$run_dir/$cluster-osd-check.log',
'--cluster', args.cluster,
'--setuser', get_ceph_user(),
'--setgroup', get_ceph_group(),
])
return (not allows_journal, not wants_journal, not needs_journal)
