Hi!

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

#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

pool contain objects like that:
10000bd3d0a.00000000
10000af4b02.00000000
100002a3b4a.00000000
100001a1876.00000000
10000bbda52.00000000
10000a09fcd.00000000
10000b54612.00000000


Where did these objects come from and how to get rid of them?


WBR,
    Fyodor.
