I had a raid5 on an onboard Intel ICH9R chip under windows. Windows crashed, as it often does, and the array became degraded. At some point during the rebuild, I was doing some hardware maintanence and unplugged one of the drives, and forgot to plug it back in.
When I booted up, the array came back as failed. I turned off the PC, plugged the drive back in and powered it back on, but the array stayed as failed.
Is there a way to recover the data? I heard dmraid supports ich9r raid volumes, but I keep getting an error saying unsupported map state 2. I found out that dmraid doesnt' support raid 5 (at least not on a ICH9R chip). I heard about this patch: http://people.redhat.com/heinzm/sw/dm/dm-raid45/, but I'm not sure how to apply it to a linux live cd. Does anyone have any idea?
Is there maybe a way to reset the metadata to make the intel controller boot the array anyway?
