Board D945GCLF2 mit Atom 330 und Gentoo Linux: SATA + PATA Softraid does not work.
with 3ware Escalade 9000 -> does not boot
with 3ware Escalade and separate HD for booting -> complete power consumption > 100 Watt/h
The aim was to find a low power board. This board has too many limitations and power consumption with HW Raid is far away from being low powered.
Will see when I get the next low power board.
Next try will be – 2 SATA HDs, one Boot partition but I have to wait for a new mainboard until next month. Will be an itx board, which is capable of all those
nifty things which makes development easy.
sda1 swap
sda2 and sdb2 mdraid /
sda3 and sdb3 mdraid /var/log
sda4 /boot
… and I had finally success with that low powered micro ATX mainboard:
- setup with mdarray raid level 1 for swap, /boot/ and root (/),
- no lvm, since bad experience with creating the initrd,
- BIOSUPDATE,
with CD ROM downloaded from intel (burn that bootable CD, baby)
- one has to mark the /boot/ partitions on both harddisks with the bootble flag, despite that seemed to be mandatory on other BIOSES,
so here is an example of “strictly following the standards (smily))
partion scheme:
sda1 + sda2 swap
sda2 + sdb2 /boot/
sda3 + sdb3 /
setup is very similar to:
Gentoo Linux x86 with Software Raid and LVM2 Quick Install Guide
Note: lvm setup seems possible, the genkernel tool is told to create the appropriate initrd. (Maybe the next time, baby)
Note: swap on raid is although slower more robust when a harddisks fails. But since the board can do 2GB RAM it will probably never used:
