I'm worried that data deleted in radosgw wasn't actually deleted from
disk/cluster.
Here's the output using df:
/dev/xvdf 1000G 779G 185G 81% /var/lib/ceph/osd/ceph-0
Quite full that disk. Now for ceph -s I get
health HEALTH_OK
<lines removed>
pgmap v256604: 2304 pgs: 2304 active+clean; 1103 GB data, 1547 GB
used, 378 GB / 2000 GB avail
<lines removed>
Still looks pretty full here.
And here's finally the output when checking the only bucket we have:
{ "bucket": "<bucket-name-removed>",
"pool": ".rgw.buckets",
"id": "4122.1",
"marker": "4122.1",
"owner": "<owner-removed>",
"usage": { "rgw.main": { "size_kb": 247104513,
"size_kb_actual": 247345748,
"num_objects": 108889}}}
This translates to around 236GB which is FAR from the around 770GB
that df and ceph -s reports. The thing is - the only way we're storing
data in ceph is through radosgw and the only bucket we have is the one
shown above (yes a pretty simple deployment). How can the stats
be so very different? Was data not actually deleted from disk? The
deletion took place yesterday so the cluster has had some time to do
any
delayed deletion if that's how it's done.
Any ideas? Thanks!
John
