Problem setting up RAID0 Array on Intel ICH7 fake-RAID.

Problem setting up RAID0 Array on Intel ICH7 fake-RAID.

Hello,

I am attempting to install Gentoo Linux on a box with a RAID0 Array.
This is a brand new box, with Intel's ICH7 chipset, and accompanying
fake-RAID chip. The RAID array works in Windows, but despite all my
attempts, I cannot get it working in Linux. I am now using a LiveCD
designed specifically to run on boxes with fake-RAID arrays. The various
software versions are:

* Grub 0.96
* device-mapper version 1.00.19
* dmraid version 1.0.0.rc6

This is the most recent version I have been able to find. I am
attempting to compile a binary of dmraid version 1.0.0.rc8, but I am
doubtful about this solving the problem. Any ideas would be welcome. =]

# dmraid --debug --verbose -ay
DEBUG: _find_set: searching isw_bhibhdiifc
DEBUG: _find_set: not found isw_bhibhdiifc
ERROR: isw: volume ARRAY is broken
DEBUG: _find_set: searching isw_bhibhdiifc
DEBUG: _find_set: found isw_bhibhdiifc
ERROR: isw: volume ARRAY is broken

DEBUG: freeing devices of RAID set "isw_bhibhdiifc"
DEBUG: freeing device "isw_bhibhdiifc", path "/dev/sda"
DEBUG: freeing device "isw_bhibhdiifc", path "/dev/sda"

Please, any idea as to how to setup this RAID array?

Chandler,

please send me the files "dmraid -rD" writes (*.dat, *.size, *.offset)
in a bzip2'ed tarball named isw-Chandler_Garruth.tar.bz2 for
investigation.

Regards,
Heinz
