Well if you have hardware raid you have to RAID first anyway, otherwise
you can do it in either order...However, I'd probably do RAID first,
then LVM, as software raiding a bunch of virtual partitions probably
takes a ton of processing power than LVM over software RAID.
As for details...There are plenty of guides for software raid out there.
Get that set up, you should have some /dev/md devices afterwards.
Then just use the LVM tools to slice up the raid devices instead of the
"actual" devices. IE give the LVM tools /dev/mdX instead of /dev/sdX.
Then make sure you are mounting things properly ;)
