Hello. I've searched a lot but couldn't find why the size of USED column in the output of ceph df is a lot times bigger than the actual size. I'm using Nautilus (14.2.8), and I've 1000 buckets with 100 objectsineach bucket. Each object is around 10B. ceph df RAW STORAGE: CLASS SIZE AVAIL USED RAW USED %RAW USED hdd 511 GiB 147 GiB 340 GiB 364 GiB 71.21 TOTAL 511 GiB 147 GiB 340 GiB 364 GiB 71.21 POOLS: POOL ID STORED OBJECTS USED %USED MAX AVAIL .rgw.root 1 1.1 KiB 4 768 KiB 0 36 GiB default.rgw.control 11 0 B 8 0 B 0 36 GiB default.rgw.meta 12 449 KiB 2.00k 376 MiB 0.34 36 GiB default.rgw.log 13 3.4 KiB 207 6 MiB 0 36 GiB default.rgw.buckets.index 14 0 B 1.00k 0 B 0 36 GiB default.rgw.buckets.data 15 969 KiB 100k 18 GiB 14.52 36 GiB default.rgw.buckets.non-ec 16 27 B 1 192 KiB 0 36 GiB Does anyone know what are the maths behind this, to show 18GiB used when I have something like 1 MiB? Thanks in advance, Marcelo.
