Hi, The cluster-wide utilization isn't the important metric here. backfill_toofull means that the destination OSD selected for the backfill is above the configured backfillfull_ratio, regardless of how much free space the cluster has overall.
Can you post the output of: ceph pg 7.0 query ceph osd dump | egrep 'nearfull_ratio|backfillfull_ratio|full_ratio' Kind regards, Sinan Op za 11 jul 2026 om 09:41 schreef listy via ceph-users <[email protected] >: > Hi guys. > > Is what ceph claims really the case? > > CEPH status is: HEALTH_WARN Low space hindering backfill > (add storage if this doesn't resolve itself): 1 pg > backfill_toofull; Degraded data redundancy: 69353/208545 > objects degraded (33.256%), 1 pg degraded, 1 pg undersized > [WRN] PG_BACKFILL_FULL: Low space hindering backfill (add > storage if this doesn't resolve itself): 1 pg backfill_toofull > pg 7.0 is > active+undersized+degraded+remapped+backfill_toofull, acting > [3,2] > [WRN] PG_DEGRADED: Degraded data redundancy: 69353/208545 > objects degraded (33.256%), 1 pg degraded, 1 pg undersized > pg 7.0 is stuck undersized for 7m, current state > active+undersized+degraded+remapped+backfill_toofull, last > acting [3,2] > > > -> $ ceph osd df tree > ID CLASS WEIGHT REWEIGHT SIZE RAW USE DATA > OMAP META AVAIL %USE VAR PGS STATUS TYPE > NAME > -1 1.61128 - 1.6 TiB 816 GiB 814 GiB > 369 KiB 1.6 GiB 834 GiB 49.48 1.00 - root > default > -3 0.53709 - 550 GiB 272 GiB 271 GiB > 147 KiB 540 MiB 278 GiB 49.44 1.00 - > host podster1 > 2 MONERO 0.39059 1.00000 400 GiB 272 GiB 271 GiB > 96 KiB 499 MiB 128 GiB 67.96 1.37 3 up > osd.2 > 5 MONERO 0.14650 1.00000 150 GiB 49 MiB 8.1 MiB > 51 KiB 41 MiB 150 GiB 0.03 0 0 up > osd.5 > -7 0.53709 - 550 GiB 272 GiB 271 GiB > 171 KiB 532 MiB 278 GiB 49.43 1.00 - > host podster2 > 0 MONERO 0.14650 1.00000 150 GiB 60 MiB 8.5 MiB > 92 KiB 51 MiB 150 GiB 0.04 0 1 up > osd.0 > 3 MONERO 0.39059 1.00000 400 GiB 272 GiB 271 GiB > 79 KiB 481 MiB 128 GiB 67.96 1.37 2 up > osd.3 > -5 0.53709 - 550 GiB 273 GiB 271 GiB > 51 KiB 543 MiB 277 GiB 49.58 1.00 - host > podster3 > 1 MONERO 0.14650 1.00000 150 GiB 447 MiB 8.5 MiB > 16 KiB 38 MiB 150 GiB 0.29 0.01 1 up > osd.1 > 4 MONERO 0.39059 1.00000 400 GiB 272 GiB 271 GiB > 35 KiB 504 MiB 128 GiB 68.06 1.38 1 up > osd.4 > TOTAL 1.6 TiB 816 GiB 814 GiB > 372 KiB 1.6 GiB 834 GiB 49.48 > > MIN/MAX VAR: 0/1.38 STDDEV: 37.28 > > I cannot "decipher" this - can you help, explain what is > (not)happening here - this "state" persists for a few days, > I do not suppose it will heal itself. > > many thanks, L. > _______________________________________________ > ceph-users mailing list -- [email protected] > To unsubscribe send an email to [email protected] > _______________________________________________ ceph-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
