you don't have one of those in hand. So, unless you're going to go buy
one *right now*, software RAID will do. (you *are* making backups, right?)
O.k., that's a useful recommendation, even if I do feel like you're
yelling at me. :-)
Heh. That's not yelling. THIS IS YELLING YOU TWIT. *grin* If you
check the archives (assuming it's in there), you'll see I was one of
those in favor of hardware RAID. Software RAID is real easy to break.
Hardware RAID, not so much -- you don't get direct access to the drives.
I have not setup software RAID in some years, but
presumably it isn't
hard?
It's not hard. And the modern tools (mdadm) make it even easier. The
only problem is booting from RAID5. You'll need to create a boot
partition that's RAID1 mirrored across all the drives in the array
so you'll be able to boot if any drive fails. Then create the RAID5
rootfs. Rinse and repeat...
I'll dig up the raidtab.conf (whatever) from milkweed to show the madness.
