I've been struggling with this one for a few days
now. We had an OSD report as near full a few days ago. Had this happen a couple of times
before and a reweight-by-utilization has sorted it out in the past. Tried the same again
but this time we ended up with a couple of pgs in a state of backfill_toofull and a
handful of misplaced objects as a result.
Consider upgrading to luminous (and then later nautilus).
Why? There you can use ceph balancer in upmap mode (at least when your
clients are new enough). No need to do any manual re weighting anymore.
^^ this besides the tips Frank gave you.
