dear list friends, i'm new to raid. i have a netfinity5000 server with 5 scsi+raid, 256mb ram, p3 450mhz 1 processor. pl guide me to configure the raid from gentoo. note: i trid to configure it using de server guide but it faild saying 'need minimum 256mb ram. i don't know y, its already has 256mb physical ram.
I've got a nearly identical setup, except i've got the second proc, but 3 9 gig drives. Here's what I did: set up a 100 meg partition (bootable) on all 3 drives. set up a second partition for the rest of the space on all 3 drives. use mdadm to create a raid 1 (mirror) with /dev/sda1 and / dev/sdb1. use mdadm to create a raid 5 with /dev/sda2, sdb2 and sdc2. create a volume group with /dev/md1 (raid 5) as the pv. then create an lv for root, one for swap, home, var and tmp, and usr. mount all that on /mnt/gentoo, then mount /dev/md0 on /boot. after untarring the stage and snapshot and chrooting into the environment, use genkernel --lvm2 --dmraid --menuconfig --install all to create my kernel (genkernel follows the /usr/src/linux symlink, so make sure it's right). the only other thing is to make sure all your scsi drivers are built into the kernel, not modules and make sure you put the initrd line in the grub.conf. at what point is it telling you you don't have enough ram? did you swapon your swap before chrooting?
