Hi All,

I have a question about "orphaned" objects in default.rgw.buckets.data pool.
Few days ago i ran "radosgw-admin orphans find ..."

[dc-1 root@mon-1 tmp]$ radosgw-admin orphans list-jobs
[
    "orphans-find-1"
]

Today I checked the result. I listed orphaned objects by command:

$# for i in `rados -p default.rgw.log ls |grep orphan.scan.orphans-find-1.rados`; do rados -p default.rgw.log listomapkeys $i; done > orphaned_objects.txt

There are a lot: xxx.__shadow_.yyy objects.

Is it possible to check if these __shadow_ are orphaned (can be removed) or belongs to any good object?
How to check if a shadow object is still in use and what object it belongs to?default.rgw.buckets.data/23a033d8-1146-2345-9f94-81383220c334.3130618.2__shadow_.-GOuvdWROljudUgTgq6u6wRR-lHoxU0_1 mtime 2017-08-16 04:01:49.000000, size 4194304
