I'm not looking for total reliability. I am building a low budget

recreating the swap partition).
I like to keep things simple-minded and not fight with anadconda.
During the install, put /boot, swap, and / on your first 2 drives as
RAID1. After that works the way you want, build whatever layout you
want with the rest of your space and either move your /home contents
and mount point over or mount it somewhere else. A nice feature of
this approach is that you can upgrade to pretty much any other
version/distro by building a new set of system disks and swapping
them in, keeping your data intact. I also like to use disks in
swappable carriers and to keep a spare chassis around. That way you
can use it for testing things and developing your next version but if
your production motherboard fails you can just move the drives to it
and keep going.
I have 4 500GB drives. Seems kind of a waste to put just /boot swap and
/ on the first 2 drives.
If 2 drives fail, I would like to still be able to be up and running
assuming I wasn't unlucky enough to have 2 drives fail in the same
mirror set.
If 3 drives fail, I'm pretty much SOL.
The most important thing is that I can easily survive a single disk
failure.
If you can deal with the space constraints of partitions that match
single disk sizes by mounting them in appropriate places it's hard to
beat RAID1. If everything fries except one drive you can still
recover the data that was on it - plus it gives you natural boundaries
for backups which you shouldn't ignore just because you have raid.
Unfortunately this is my backup server, and also file server. While I
may move the file server part out to another box in the future, for now
it's going to be serving two roles. I would like to be able to depend
on it.
In the future I might set up a backup of this server to be on Amazon's
S3. Is there a linux program that interfaces with it?
