| you are using hdd?
Hi all. I deploy a ceph cluster with Mimic 13.2.4. There are 26 nodes, 286 osds and 1.4 PiB avail space. I created nearly 5,000,000,000 objects by ceph-rgw, each object is 4K size. So there should be 18TB * 3 disk used. But `ceph df detail` output shows that the RAW USED is 889 TiB Is this a bug or I missed something?
ceph df GLOBAL:
SIZE AVAIL RAW USED %RAW USED
1.4 PiB 541 TiB 889 TiB 62.15
POOLS:
NAME ID USED %USED MAX AVAIL OBJECTS
.rgw.root 7 4.6 KiB 0 12 TiB 20
default.rgw.control 8 0 B 0 12 TiB 8
default.rgw.meta 9 0 B 0 12 TiB 0
default.rgw.log 10 0 B 0 12 TiB 175
test.rgw.buckets.index 11 0 B 0 39 TiB 35349
test.rgw.buckets.data 12 18 TiB 59.35 12 TiB 4834552282
test.rgw.buckets.non-ec 13 0 B 0 12 TiB 0
test.rgw.control 17 0 B 0 39 TiB 8
test.rgw.meta 18 3.0 KiB 0 39 TiB 13
test.rgw.log 19 63 B 0 39 TiB 211
Here is `ceph -s` output cluster:
