I have two xraid's that are on /dev/sda1 and /dev/sdb1. The device on

NO
However, you could make a VG with just sdb1 instead of formatting it
ext3, create the LV on it, format /that/ as ext3 and copy the sda1 data
to the new LV (on sdb1). Once copied off, you can make a PV over top of
sda1 (erasing it) and add it to the same VG, making your VG span both
devices without losing data.
This only works if you're not booting off sda1 and if sdb1 is at least
as big as the data set on sda1.
