Synopsis

Description
|
|
|
|
|
===========
|
|
|
|
|
|
|
|
|
|
:program:`rgw-orphan-list` is an *EXPERIMENTAL* RADOS gateway user
|
|
|
|
|
administration utility. 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.
|
|
|
|
|

|

|
|
