Hi,
I am wondering how a PG gets marked backfill_toofull.
I reweighted several OSDs using ceph osd crush reweight. As expected,
PG began moving around (backfilling).
Some PGs got marked +backfilling (~10), some +wait_backfill (~100).
But some are marked +backfill_toofull. My OSDs are between 25% and 72% full.
Looking at ceph pg dump, I can find the backfill_toofull PGs and
verified the OSDs involved are less than 72% full.
Do backfill reservations include a size? Are these OSDs projected to
be toofull, once the current backfilling complete? Some of the
backfill_toofull and backfilling point to the same OSDs.
I did adjust the full ratios, but that did not change the
backfill_toofull status.
ceph tell mon.\* injectargs '--mon_osd_full_ratio 0.95'
ceph tell osd.\* injectargs '--osd_backfill_full_ratio 0.92'
