Thanks. I realized logs weren't rotating, and that was the reason my 
partition was filling up. Now that logs are rotating properly, I am 
using very little of that partition, and so I'm going with the, "if it 
ain't broken, don't fix it" advice on this one. Will monitor disk use, 
of course, but for now no reason to mess with partitions... Btw, I get 
"No volume groups found" for all of the commands. Haven't checked the 
old drive to see if this is also true there.

thanks again,
