[ceph-users] speed up individual backfills

Hi, I have 15628 misplaced objects that are currently backfilling as follows: 1. pgid:14.3ce1 from:osd.1321 to:osd.3313 2. pgid:14.4dd9 from:osd.1693 to:osd.2980 3. pgid:14.680b from:osd.362 to:osd.3313 These are remnant backfills from a pg-upmap/rebalance campaign after we've added 2 new racks worth of osds to our cluster. Our mon db is bloated so I'm wanting to trim the mon db before continuing the next pg-upmap/rebalance campaign. So, my question is: Is there any way I can speed up the backfill process on these individual osds? Or hints to trace out why these are so slow? Regards
