Ok I'm convinced, I'll use RAID.
I found this page
http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/custom-guide/ch-so
ftware-raid.html which you'd think would be the perfect set of
instructions. BUT IT'S NOT!!
The raid instruction are a little vague.
I'm trying to follow Samuel's original instructions:
-=-=-=- Use software raid 5 on each disk: raid 1 /boot (~100M) Raid 1 as you can't boot off of raid 5!!! raid 5 swap raid 5 / (~2G) raid 5 /var (Most of the rest of your space, for your logs and /var/www) -=-=-=-
(Following the steps in the above document) Step 5 says "For Allowable Drives, select the drive(s) on which RAID will be created. If you have multiple drives, all drives will be selected here and you must deselect those drives which will not have the RAID array on them."
But if I select more than one drive I get the message "Partitions of type 'software RAID' must be constrained to a single drive. This is done by selecting the drive in the 'Allowable Drives' checklist."
Ok, So what's the deal with that? How can you have RAID if you're forced
to only use one disk? I don't get it!!
You need to create a partition that will be a part of the raid array on each disk. So the followiing is what I do:
Create a partition of type raid on disk 1 ~100M via the new partition button
Create a raid partition of type raid on disk 2 ~100M via the new partition button
Create a raid partition of type raid on disk 3 ~100M via the new partition button
Create the raid array using the above 3 disks using the raid buton
Repeat for all arrays
I've always thought Red Hat's method was a little strange;-) Why not let me create multiple partitions on each disk in one stoke.
AAHH!!
