thanks Bill.  i appreciate the detail. :)  i'll give this a try and
re-document the steps.  i may have a spare 200GB that i can start out
with, and that would allow me to leave my current system intact so i
could do the upgrade over several days.

install spare drive as primary and do the install/config
stick old drive back in to make use of existing db rules, recordings,. etc.
clean 300 GB drive and format with XFS
copy recordings from original 200GB drive to 300GB drive
dump db to the network
reinstall spare drive as primary, restore db, mount 300GB drive as /myth/tv
primary drive will contain system, db, myth.  300GB will only be /myth/tv
and on the seventh day i can rest and enjoy my MythTv with more
recording space. :D

thanks again
