    11I like this idea, but I'd like to suggest a FR to go along with this Enhancement.  Specifically I am concerned that the storage nodes have no way to restrict how much disk space they use on a file system, other than the negative value provided by the reserved_space config option.  Would the enhancement to display the storage node's capacity then calculate and report as available only the difference between available disk space for the file system the node is running on and the reserved_space setting?

    3 If there was a disk space setting, the reported disk space value for a storage node would be more accurate.  For example, a storage node run on a volume group could all of a sudden find itself with expanded available space unintentionally, since adding more PV's to an LV would mean that the reserved_space value would grow the available node's capacity perhaps beyond that which a server admin originally intended.

     5It's easy to grow a storage nodes capacity, but how does one shrink it after the fact?
