we need to add at least a few here:

       -d[<value>]
              Enable debug logging. Value can be 0, 1 or 2.
              0 disables debug logging
              1 sends debug logs to stderr (implies -f option)
              2 sends debug logs to syslog
              If -d is specified without a value then 1 is assumed.

       -t<timeout>
              Specifies the timeout for commands to run  around  the  cluster.
              This should not be so small that commands with many disk updates
              to do will fail, so you may need to  increase  this  on  systems
              with very large disk farms.  The default is 30 seconds.

Not sure we should make -T also a parameter instead of a meta_timeout.
