They won't be messed up.  ZFS will figure out, using its metadata, which
drive is part of what pool despite the device name changing.  I don't
use glabel or GPT so I can't comment on whether or not those work
reliably in this situation (I imagine they would, but I keep seeing
problem reports on the lists when people have them in use.......)
