That would have been my strong suggestion: do a dd of the JFS partition
and resize when done. (Does parted understand JFS? Use that if it does:
it'll be even faster.)
Given a pretty pedestrian 30MB/s transfer rate you're talking 10 hours to
complete the copy. Like Les said: I can't imagine being able to take a
production backup server down for a *week*, and if it's not a production
server then you probably aren't copying the pool! :)
