Have you recently upgraded from an ancient version of parted, or changed
the script to use M instead of m?  iirc, M stands for MebiByte which
requires an exact power of two size.  m is for megabyte and leaves a
little room for rounding and so the two values can be the same and will
be rounded slightly to fit.
