I have a ceph cluster that shows a different space utilization in its status
screen than in its bucket stats. When I copy the contents of this cluster to a
different ceph cluster, the bucket stats totals are as expected and match the
bucket stats totals.
output of "ceph -s" on the first ceph cluster:
cluster:
id: 9de06f94-a841-4e17-ac7c-9a0d8d8791b8
health: HEALTH_OK
services:
mon: 3 daemons, quorum idb-ceph4,idb-ceph5,idb-ceph6
mgr: idb-ceph4(active), standbys: idb-ceph5, idb-ceph6
osd: 172 osds: 168 up, 168 in
rgw: 5 daemons active
data:
pools: 16 pools, 9430 pgs
objects: 272.4 M objects, 360 TiB
usage: 1.1 PiB used, 333 TiB / 1.4 PiB avail
pgs: 9410 active+clean
11 active+clean+scrubbing
9 active+clean+scrubbing+deep
io:
client: 151 MiB/s rd, 838 op/s rd, 0 op/s wr
taking the sum of all the sizes of the buckets gives:
526,773,819,875,727 bytes or 526.7TB.
How can the status usage of objects be 333TiB and the bucket totals be 479TiB?
