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)

I faced this issue once before.
The problem is - function is query for osd.0 instead your osd.21.
Change in main.py

'-i', '0',

to 21 (your osd number)

'-i', '21',

and try again.
