If you're creating a new slice, that would be mfid0s2, because
mfid0s1 is the 1st slice ("DOS primary partition") carrying the
partitions a, swap, d, e, f, g. If I remember correctly, h is
the last partition letter that can be assigned, so this one
should be available.
Problem: The 1st slice mfid0s1 is already of fixed size, so
you cannot add a new partition here without growint that
slice first. Attention, that step isn't free of danger and
should be done with a backup at hand, just in case, and
because you _always_ need a backup. :-)
This problem is not a problem if you create a 2nd slice
mfid0s2 to use it separately.
If you can _really_ create mfid0s2 as a slice, you only need
to format it, e. g. "newfs -U /dev/mfid0s2" which creates
mfid0s2c which in turn is called mfid0s2). You can then assign
that new partition (the one covering the whole slice) to
a new mountpoint, e. g. /data, /stuff or whatever you want.
There are also means to "merge" this partition into some
mountpoint that is already occupied, e. g. /home, maybe via
"mount -o union" including all possibly negative consequences).

Without wiping the whole disk(s)?
