I had a raid5 on an onboard Intel ICH9R chip under

crashed, as it often does, and the array became

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
- 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?
One of the best live Linux CD's out there is the FC8 http://mirrors.kernel.org/fedora/releases/8/Live/
uses the 2.6.23 kernel. Knoppix 5.1 is Jan07 and kernel 2.6.19
BTW, I hear a lot of negative things about dmraid and fakeraid. I have an FC5 desktop box dual booting WinXP and FC5 on fakeraid/Raid0 thats been perfect for over 3 years. That includes a kernel upgrade in FC5, which required me to run mkinitrd (since it froze during boot) to get it working.
