I'm setting up Centos4.2 on 2x80GB SATA drives.

The partition scheme is like this: /boot = 300MB / = 9.2GB /home = 70GB swap = 500MB

The RAID is RAID 1. md0 = 300MB = /boot md1 = 9.2GB = LVM md2 = 70GB = LVM md3 = 500MB = LVM

Now, the confusing part is:

1. When creating VolGroup00, should I include all PV (md1, md2, md3)? Then

create the LV. 2. When setting up RAID 1, should I make those separated partitions for /, /home, and swap? Or, should I just make one big RAID device?

The future purpose of using LVM is I want to be able to expand any partitions that would run out of space into a new disk.

Personally, I would do:

md0 = 300MB (/boot) md1 = 500MB (swap) md2 = remainder (pv.00)

I would then create a single volume group on md2, create / and home, but I would leave 20-30% of the VG empty so you can expand later. That would work out to like 10GB /, and 50GB /home, and leave you 15 or so GB for expansion.
