I'm working on shrinking a raid array and need some clarification
on where the metadata goes and how large it is.  I have used -G
with -Z and -z to reduce the used size of each disk, but the man
page says you need some extra space at the end of the disk for the
metadata ( format 1.0 ), but doesn't specify exactly how much.  I
need to know what the exact size of the reduced partition should
be.

I just noticed that reducing the used dev size has not moved the
metadata, so it is looking like it just isn't possible to shrink the
md partition with metadata format 1.0?
