17 :program:`rgw-orphan-list` is an *EXPERIMENTAL* RADOS gateway user
18 administration utility. It produces a listing of rados objects that
19 are not directly or indirectly referenced through the bucket indexes
20 on a pool. It places the results and intermediate files on the local
21 filesystem rather than on the ceph cluster itself, and therefore will
22 not itself consume additional cluster storage.
24 In theory orphans should not exist. However because ceph evolves
25 rapidly, bugs do crop up, and they may result in orphans that are left
28 In its current form this utility does not take any command-line
29 arguments or options. It will list the available pools and prompt the
30 user to enter the pool they would like to list orphans for.
32 Behind the scenes it runs `rados ls` and `radosgw-admin bucket
33 radoslist ...` and produces a list of those entries that appear in the
34 former but not the latter. Those entries are presumed to be the
40 This utility is currently considered *EXPERIMENTAL*.
42 This utility will produce false orphan entries for unindexed buckets
43 since such buckets have no bucket indices that can provide the
44 starting point for tracing.
49 At present there are no options.
61 :program:`radosgw-admin` is part of Ceph, a massively scalable, open-source,
62 distributed storage system. Please refer to the Ceph documentation at
