Usage: /usr/bin/rgw-gap-list [-m] [-p <pool>] [-t <temp_dir>]

Where:
  -m               Optionally, run the two listings in multiple threads.
                   --See NOTE below--

  -p <pool>        The RGW bucket data pool name, if omitted, pool name
                   will be prompted for during execution.
                   Multiple pools can be supplied as a space separated
                   double quoted list.

  -t <temp_dir>    Optionally, set the directory to use for temp space.
                   This may be required if /tmp is low on space.

NOTE: This tool is currently considered to be EXPERIMENTAL.

NOTE: False positives are possible. False positives would likely
      appear as objects that were never deleted and are fully
      intact. All results should therefore be verified.

NOTE: Multithread listing may increase performance but may also increase
      the risk of false positives when the cluster is undergoing
      modifications during the listing processes. In addition to the
      above, false positives might also include objects that were
      intentionally deleted.
