ok, so in your setup the OS is totally separate from the data itself?
indeed, almost all my servers are setup this way, too. A pair of
smaller disks, 36GB or 80GB are mirrored for the OS and software, then
populate the rest with large disks in raid10 or raid5 for whatever task
this server is intended for (database or bulk storage, or whatever).
This strategy is probably most useful when you have several machines
that are similar enough to swap drives and keep a spare chassis around
that you can use as a backup and to build/test your next major update. I
generally use smaller disks for the 1st pair, but if there is extra
space you can use it for something that changes slowly enough that you
would be able to rsync it over to the replacement before the swap. The
main thing is to not include the OS drives in LVM or RAID0 with the
others that you don't expect to swap.
