History:

First we started out with two different commands, dpool and npool.  dpool(1M) was to be run on the data server and npool(1M) was to be run on the metadata server.  Then, rather than having two different commands that didn't have any association (via the name) with pNFS we decided to merge the two commands into one single pnfs(1M) command with mds (for metadata server) and ds (for data server) subcommands.  The most recent design is shown above.  The ds subcommand of pnfs(1m) has been removed in lieu of using the zfs(1M) command and pnfs(1M) has been renamed to pnfsadm(1M) due to feedback from our user interface review board.  pnfsalloc(1M) was the simple policy engine interface.  This interface has been rolled into pnfsadm(1M).
