    4 # Script to monitor that a particular filesystem stays mounted            #
    5 #  Primarily useful for when you have a filesytem on a shared disk        #
    6 # Provided as a tool to be called from 'monitorhasrv'                     #
    7 #                                                                         #
    8 # USAGE:   fs.monitor devpath mountpoint                                  #
    9 #    EG:   fs.monitor /dev/md/metaset/dsk/d12 /export/home                #
   10 #                                                                         #
   11 #  Standard UNIX status: returns 0 on okay, non-0 on fail.                #
