Comment 4 for bug 1879749

ceph-mon permissions for rbd-mirror clients:

rbd_mirror_caps = collections.OrderedDict([
    ('mon', ['profile rbd; allow r']),
    ('osd', ['profile rbd']),
    ('mgr', ['allow r']),
])

vs upstream docs:

ceph auth get-or-create client.rbd-mirror-peer mon 'profile rbd-mirror-peer' osd 'profile rbd'
