And when you are doing your custom layout, select RAID rather than New in
the menu for making partitions. The RAID option allows you to setup
partitions on different disks and then combine them into a software raid.
You can select the RAID type, and which partitions go into each RAID
device. I have used this many times, and Troy is correct: as long as you
use the force primary partition option, the partitions do not get moved around.

I'm trying to do a clean install of SL 5.4. I'm booting from an SL
5.4
x86_64 DVD. When I get to the point of custom partitioning my drives,
Anaconda makes a mess of things. I have 4 drives and I want 4 partions on
each drive. The first partion will be `/boot', next `/', then `/data', and
finally a swap partion. As I create each partition on each drive, Anaconda
will suddenly rearrange the order of the partions. When I go onto another
drive, the order may be different than the last drive I just partitioned.
When I try to do the 4th and last partition, I get an `Extended' 4th
partion
(which is empty) and a real 5th partition, instead of a simple single
partition.
In the end, what I want is the first partition on each drive combined
into a software RAID 1 and be `/boot'. The next 2 sets will be software
RAID
0's and `/' & `/data'. The final partitions will be 4 separate swap
partitions that the OS will take care of.
I've tried creating all the partitions on one drive and then moving
onto
the next one and the next one, but it scrambles things up. I've tried
creating the first partition on each drive, then combining them into the
RAID
1 md0 device, and specifying the files system type, and mount point
`/boot'.
Next I go onto the next partition, which I've tried as a software RAID 0
partition and swap at various times. This one usually works, but not
always.
When I get to the 3rd partition, then it will suddenly rearrange the
partitions on that drive. I've even seen it suddenly create a swap
partition
on a different drive than what I'm actually working on.
I've done this with earlier versions of SL, but I don't remember
having
this much trouble with Anaconda randomly rearranging things and creating an
extra unneeded partion. Any insights would be greatly appreciated.
Thanks.
What *I* would do with something that complicated.
I would do a <Ctrl>-<Alt>-F2 on the screen before that and do all the
partitions by hand. Then on the customizing screen, you just have to link
them together.
But if you are going to do it by the graphical install, make *sure* that you
select "Primary Partition" for each and every partition. The one partition
that you don't do that to is going to get popped over to an extended
partition.
