Hi, ceph version 13.2.2 (02899bfda814146b021136e9d8e80eba494e1126) mimic (stable) Cannot understand why ceph shows only 17TiB "MAX AVAIL" for pools while GLOBAL AVAIL=105TiB. What I expect is that for pools with replica count 3 MAX AVAIL should be roughly GLOBAL AVAIL/3 ~ 35TiB In excerpt below pool xxxxxxxxxxxx has replica count 2, the rest have 3 # ceph df detail GLOBAL: SIZE AVAIL RAW USED %RAW USED OBJECTS 250 TiB 105 TiB 145 TiB 57.98 12.71 M POOLS: NAME ID QUOTA OBJECTS QUOTA BYTES USED %USED MAX AVAIL OBJECTS DIRTY READ WRITE RAW USED xxxxxxxxxxxx 9 N/A N/A 1.0 GiB 0 25 TiB 298 298 85 KiB 9.9 KiB 2.0 GiB ssssssss 17 N/A N/A 10 TiB 37.72 17 TiB 2621445 2.62 M 471 MiB 367 MiB 30 TiB eeeeeeeee 47 N/A N/A 532 B 0 17 TiB 1 1 1 B 9 B 1.6 KiB yyyyyyyyyyyyyyyyy 48 N/A N/A 2.1 TiB 11.36 17 TiB 554933 554.9 k 194 MiB 39 MiB 6.4 TiB ...... Any ideas where space is hidden or I wrongly interpret GLOBAL AVAIL? Best ragards Ugis
