Description
Hi!
- ceph version
ceph version 13.2.4 (b10be4d44915a4d78a8e06aa31919e74927b142e) mimic (stable)
After removing all files from cephfs I see that situation:
#ceph df
POOLS:
NAME ID USED %USED MAX AVAIL OBJECTS
fsd 2 0 B 0 233 TiB 11527762
fsdtier 3 240 KiB 0 9.6 TiB 2048
#rados df
POOL_NAME USED OBJECTS CLONES COPIES MISSING_ON_PRIMARY UNFOUND DEGRADED RD_OPS RD WR_OPS WR
fsd 0 B 11527761 270 69166566 0 0 0 137451347 61 TiB 46169087 63 TiB
fsdtier 240 KiB 2048 0 6144 0 0 0 234897999 53 TiB 199347641 8.5 TiB
fsdtier pool is a tier for fsd pool.
pool fsd contain objects like that:
10000bd3d0a.00000000
10000af4b02.00000000
100002a3b4a.00000000
100001a1876.00000000
10000bbda52.00000000
10000a09fcd.00000000
10000b54612.00000000
pool fsdtier do not contain any object:
#rados -p fsdtier ls|wc -l
0

The garbage is just inodes left behind, probably by some MDS bug in the past. Presumably you don't need these files anymore since you deleted the rest?
- Tracker changed from Bug to Support

The previous version was 13.2.1 ugraded to 13.2.2 upgraded to 13.2.4. I did not see in the description of the corrected errors anything like this.
Yes, I don’t need these files anymore.
What about 2048 objects in a different pool?
- Status changed from New to Closed

I would just delete both pools and recreate them.
