Hi Stefan,
I went through the git history and this appears to be expected, at
least for some definition of expected. Commit [1] clearly recognized
the problem and made the
rbd: failed to query services: (13) Permission denied
error that you ran into with "rbd mirror pool status" non-fatal.
Also, there is a comment in the respective PR [2] acknowledging that
even
caps mgr = "profile rbd"
cap (which your client.rbd-mirror user doesn't have and rbd-mirror
daemon doesn't actually need) would NOT be sufficient to resolve the
error because "our profiles don't give the average user access to see
Ceph cluster services".
