6.2 Mount Options

        Refer to "man mount" for all your options and details

        -ro     Read only

        -rw     Mount the filesystem read and write, but can be restricted
                by the server, and a warning is flagged

        -blocksize=1024         block size 
        -rsize=4096     Read buffer size
        -wsize=4096     Write buffer size

        -intr   allow keyboard interrupts to kill the process that is hung
                waiting for the server that is down.

        -nointr No keyboard interrupts allowed.

        -soft   if the server fails to respond, return an error after the
                timeout period ( -timeo=value ) expires and don't bother to try again

        -hard   if the server fails to respond, retry until it does respond
                ( Note that this is the default option )

                down as all the other servers need to wait for it to come back.
