[gentoo-amd64] Supermicro H8QME-2 motherboard

[Curtis Richards]

Hi All,

Has anyone emerged Gentoo on a Supermicro  H8QME-2  motherboard with the 
on board nVidia raid controller?

Are there any 'gotcha's'?  Or am I about to find why pioneers get all 
those arrows in their backs?

Thanks in advance for your help.

Seconded.  It doesn't really work.  You can define arrays in the controller
configuration but when you boot Gentoo it sees separate drives, and what little
RAID hardware there is on the board doesn't do anything.  You're better off with
LVM over software RAID from the get-go.

I'd prefer md kernel-based RAID in any case, just as I've implemented it
here on a Silicon Image SATA-RAID chipset.  There's firmware/kernel-dm
based RAID for it, but I prefer the md-kernel-based-RAID.

If a drive goes out, no big deal.  However, with md-based RAID, the mobo
or SilImg chip can go out as well, and all I have to do is plug the drives
into any SATA standard hardware, rebuild the kernel with the appropriate
SATA driver, and I'm off and running.  Try /that/ with the proprietary
hardware solutions!

FWIW, four SATA drives, RAID-1 /boot, RAID-6 (so two-way striped, two
independent parity stripes, two of the four can go down) main system,
RAID-0 (4-way striped for speed and capacity, no redundancy) temporary
stuff (/tmp and the like, ccache, portage tree, kernel trees, everything
that's easily redownloadable or just scratch, thus redundancy not needed).
