If you turn up client debugging to 20 it should output a lot more
information (unless the MDS is returning that error code, which it
might be — in which case, go through all the MDS admin socket commands
and look for something useful, or turn up debugging there). But
realistically, if those 3 inactive PGs are part of your metadata pool,
I presume that's why you're getting errors.
