Hi
Ceph version 17.2.3 (dff484dfc9e19a9819f375586300b3b79d80034d) quincy
(stable)
Looking at this:
"
Low space hindering backfill (add storage if this doesn't resolve
itself): 2 pgs backfill_toofull
"
"
[WRN] PG_BACKFILL_FULL: Low space hindering backfill (add storage if
this doesn't resolve itself): 2 pgs backfill_toofull
pg 3.11f is active+remapped+backfill_wait+backfill_toofull, acting
[98,51,39,100]
pg 3.74c is active+remapped+backfill_wait+backfill_toofull, acting
[96,120,58,48]
"
But the disks are noway near being full as far as I can determine, so
why backfill_toofull? The PGs in question are in the rbd_data pool.
