13 rgw-orphan-list is an EXPERIMENTAL RADOS gateway user administration
14 utility. It produces a listing of rados objects that are not directly
15 or indirectly referenced through the bucket indexes on a pool. It
16 places the results and intermediate files on the local filesystem
17 rather than on the ceph cluster itself, and therefore will not itself
18 consume additional cluster storage.
19
20 In theory orphans should not exist. However because ceph evolves
21 rapidly, bugs do crop up, and they may result in orphans that are left
22 behind.
23
24 In its current form this utility does not take any command-line argu‐
25 ments or options. It will list the available pools and prompt the user
26 to enter the pool they would like to list orphans for.
27
28 Behind the scenes it runs rados ls and radosgw-admin bucket radoslist
29 ... and produces a list of those entries that appear in the former but
30 not the latter. Those entries are presumed to be the orphans.
31
33 This utility is currently considered EXPERIMENTAL.
34
35 This utility will produce false orphan entries for unindexed buckets
36 since such buckets have no bucket indices that can provide the starting
37 point for tracing.
38
40 At present there are no options.

43 Launch the tool:

45 $ rgw-orphan-list

48 radosgw-admin is part of Ceph, a massively scalable, open-source, dis‐
49 tributed storage system. Please refer to the Ceph documentation at
50 http://ceph.com/docs for more information.
