What advantages, if any, would lvm have over this set up?
How about flexible filesystem resizing? If you did it the way I
suggested: 512MB /boot, 512MB /tmp, you have like 960GB of space
to carve anyway you like. You also get lvm snapshots which you
won't get with raid seeing that this is supposed to be a backup
server too.
Yea, I think for these reasons I will use lvm. I have set up a
system as follows:
/boot raid 1 200mb 4 drives no spares (I guess this makes 4 copies
of the data?)
You have four disks which will be paired into two pairs. If one pair
goes, everything goes. Might as well use one pair for /boot and the
other for /tmp.
I'm not quite sure I understand? This is raid1, not raid10. While
I'm not sure exactly how raid1 works with 4 drives, I'm assuming
everything is a copy of a copy of a copy...
So how would 2 drives going out kill the whole raid1 device?
NOT everything is raid1 now is it? Your data/system is on raid10 RIGHT?

Well apparently not. I decided to go with 2 raid1's with LVM striped on
top of it. The previous comment was specifically about /boot on raid1.
I have tested it, and it worked flawlessly even with 2 drives taken
out. All my arrays held up. Of course if I took out one of the wrong
drives, I would've lost my data, but I think the book partition would've
been ok.
