how easy to recover RAID5?



I'm looking to RAID5 together about three 600GB drives, using Fedora
Core (7 at the moment, but I anticipate using 8). (Come to think of
it, we may end up using CentOS. Either way....)

I found how it's easy to set up a software RAID5 using Disk Druid.
Lots of pros and cons regarding the different RAIDs. But, I'm having
trouble finding information on how to recover a RAID 5. I don't want
to irrevocably tie our data into three drives if something "bad"
happens to one, I can't easily restore.

I take it of one of the three drives goes out, the entire array is
unusable until the drive is replaced, right? But then what? You pop in
a new drive, boot up--something automagically happens to recover the
data and redistribute bytes onto the new drive? Or do I have to boot
up with Knoppix/FC console disk and run something?

If someone could point me in a direction so I can find out, I'd
appreciate it.
Thanks!
-Liam
