Usage: riak-admin cluster <command>

The following commands stage changes to cluster membership. These commands
do not take effect immediately. After staging a set of changes, the staged
plan must be committed to take effect:

   join <node>                     Join node to the cluster containing <node>
   leave                           Have this node leave the cluster and shutdown
   leave <node>                    Have <node> leave the cluster and shutdown

   force-remove <node>             Remove <node> from the cluster without
                                   first handing off data. Designed for
                                   crashed, unrecoverable nodes

   replace <node1> <node2>         Have <node1> transfer all data to <node2>,
                                   and then leave the cluster and shutdown

   force-replace <node1> <node2>   Reassign all partitions owned by <node1> to
                                   <node2> without first handing off data, and
                                   remove <node1> from the cluster.

Staging commands:
   plan                            Display the staged changes to the cluster
   commit                          Commit the staged changes
   clear                           Clear the staged changes

Status and information commands:
   status                          Display a concise summary of node membership
                                   availability and ring ownership.

   partitions [--node=<node>]      Print primary, secondary and stopped
                                   partition indices and ids for the current
                                   node, or for the specified node.

   partition-count [--node=<node>] Print the cluster-wide number of
                                   partitions or the number of partitions
                                   on the specified node.

   partition id=<id>               Convert the given partition id to the
                                   matching index.

   partition index=<index>         Convert the given partition index to
                                   the matching id.
