That worked! Thanks.

morninglightmountain# gpart destroy ad1
ad1 destroyed
morninglightmountain# gpart create -s vtoc8 ad1
ad1 created
morninglightmountain# gpart show ad1
=>        0  312445125  ad1  VTOC8  (149G)
          0  312445125       - free -  (149G)

on these disks.
All is well now. Thanks again.
