It produces a listing of rados objects that +are not directly or indirectly referenced through the bucket indexes +on a pool. It places the results and intermediate files on the local +filesystem rather than on the ceph cluster itself, and therefore will +not itself consume additional cluster storage. + +In theory orphans should not exist. However because ceph evolves +rapidly, bugs do crop up, and they may result in orphans that are left +behind. + +In its current form this utility does not take any command-line +arguments or options. It will list the available pools and prompt the +user to enter the pool they would like to list orphans for. + +Behind the scenes it runs `rados ls` and `radosgw-admin bucket +radoslist ...` and produces a list of those entries that appear in the +former but not the latter. Those entries are presumed to be the +orphans. + +Warnings +======== + +This utility is currently considered *EXPERIMENTAL*. + +This utility will produce false orphan entries for unindexed buckets +since such buckets have no bucket indices that can provide the +starting point for tracing. + +Options +======= + +At present there are no options. + +Examples +======== + +Launch the tool:: + + $ rgw-orphan-list + +Availability +============ + +:program:`radosgw-admin` is part of Ceph, a massively scalable, open-source, +distributed storage system.
