Looks like you need 3.2.6. Probably unrelated, but in case you were unaware, ICHxR chipsets have snared me in the past with bugs that were later corrected by firmware updates from Intel. If I remember correctly from upthread, you were at one point attempting to / running this array with such hardware. If this is still an option, you might check your firmware version and the release notes for any more recent release. This won't fix software RAID but it could conceivably coax the ICH10R into assembling the array. -- Charles
