Aloha,

I'm trying to use parted to initialize a 7TB "disk" that will end up with
xfs as its file system.  I got it to work in interactive mode after some
experimenting.  But I'd like to be able to use the command line.

1.  The documentation section 1.5 does not mention --disable-device-mapper .

2.  Section 2.4.7, mkpart, says:

       mkpart [part-type fs-type name] start end

    I tried:

       (parted) mkpart 0 7gb
       mkpart 0 7gb
       End? 7000
       7000

        1      7000MB  7000MB  512B               0

    .  I understand why I got 7000MB from 7000.  I don't understand why
    there was not either an error message because the "gb" was lower case
    or the "7gb" did not take.

3.  I'm guessing that the following has to do with the "sensible ranges"
    logic, but it is not too friendly.

    If it says the disk is 7000GB, it should accept 7000000MB as a valid
    end value.

4.  What happened here?

5.  Which number is invalid?

    Normally "[part-type fs-type name]" means that those values are
    optional.  They do not appear to be.

    How does one specify "-1s" on the command line?

       address@hidden:~/] # /h/thomas/src/parted/parted-1.9.0/parted/parted 
--script -- /dev/sdb mkpart  0.0 -1s
       /h/thomas/src/parted/parted-1.9.0/parted/.libs/lt-parted: invalid token: 
-1s
       Error: Expecting a file system type.
       address@hidden:~/] #

    Optional?
