Hi,

I followed http://people.freebsd.org/~rse/mirror/ to create a software
RAID mirror.  I have two 75G drives in the machine.  I allocated 74G to
the filesystem on each drive and 1 G to swap.  When I blanked ad1 and
created ad1s1, I didn't notice that it had taken up the whole of the
drive.  Can I shrink the mirror partition and have two swap partitions,
or if that is not possible, how would I go about creating a "mirrored"
swap partition?

# bsdlabel /dev/mirror/gm0s1
# /dev/mirror/gm0s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:   524288        0    4.2BSD     2048 16384 32776 
  c: 156296322        0    unused        0     0      
  d:  1048576   524288    4.2BSD     2048 16384     8 
  e: 20971520  1572864    4.2BSD     2048 16384 28552 
  f: 132643453 22544384    4.2BSD     2048 16384 28552
