I've got a nearly identical setup, except i've got the second proc, |
| 14 |
but 3 9 gig drives. |
| 15 |
Here's what I did: set up a 100 meg partition (bootable) on all 3 |
| 16 |
drives. set up a second partition for the rest of the space on all 3 |
| 17 |
drives. use mdadm to create a raid 1 (mirror) with /dev/sda1 and / |
| 18 |
dev/sdb1. use mdadm to create a raid 5 with /dev/sda2, sdb2 and |
| 19 |
sdc2. create a volume group with /dev/md1 (raid 5) as the pv. then |
| 20 |
create an lv for root, one for swap, home, var and tmp, and usr. |
| 21 |
mount all that on /mnt/gentoo, then mount /dev/md0 on /boot. after |
| 22 |
untarring the stage and snapshot and chrooting into the environment, |
| 23 |
use genkernel --lvm2 --dmraid --menuconfig --install all to create my |
| 24 |
kernel (genkernel follows the /usr/src/linux symlink, so make sure |
| 25 |
it's right). the only other thing is to make sure all your scsi |
| 26 |
drivers are built into the kernel, not modules and make sure you put |
| 27 |
the initrd line in the grub.conf. at what point is it telling you |
| 28 |
you don't have enough ram? did you swapon your swap before chrooting? |
