Reinstall Gentoo without losing RAID?

So my mythbox appears to be completely FUBAR and I was considering reinstalling. Then I remember that I have my media disks as a RAID 0 and I was wondering if there's a way to reinstall without loosing all the data? Much of it is fairly easy to copy off, I just don't want to have to go through all that trouble of getting it off and getting it back on the drives.

Anyone know a way?

If it is Linux Software RAID, just copy the config to the new setup before you access it.

even if you forget the config file containing the raid info (mdadm.conf or raidtab or whatever) you can always re-assemble a linux software raid array if you know which devices are part of the array.
hell, you can put the disks on different ata/sata ports or even on another controller, and still re-assemble the array. read through the mdadm man page.

edit: come to think of it, my server, which has 2 raid0's and 1 raid1 has NO raid config file whatsoever. the raid subsystem always finds the disks and assembles them perfectly. of course I should probably generate a config file just in case :)

Cool, thanks. I just wanted to make 100% certain that I'd be okay.
