Comment 40 for bug 372170

I am a newcomer to Linux. I'm trying to get a dual-boot Windows XP x64 working with Ubuntu 9.04. The machine has an ICH10R motherboard with a new Windows OS load on a two-drive RAID 1 array using the Intel Matrix Manager RAID management. After initially loading XP, I started Ubuntu from a Live CD and using the included dmraid had errors when trying to set up the RAID using the instructions at:

https://help.ubuntu.com/community/FakeRaidHowto

When entering
$ sudo dmraid -ay

I had the following errors:

Error: isw device for volume "Volume0" broken on /dev/sda in RAID set "isw_df . . .
Error: wrong # of devices in RAID set "isw_df . . ." [1/2] on /dev/sda

These errors were repeated for /dev/sdb

I did not try the "$ sudo dmraid -r -d" entry. After searching I found Rob's request for testing the dmraid patch for ICH10R. I updated with his new version of dmraid, and tried the sudo dmraid -r -d entry. Here are the results:

ubuntu@ubuntu:~$ sudo dmraid -r -d
DEBUG: isw metadata found at 640135027712 from probe at 640135027712

DEBUG: isw metadata found at 640135027712 from probe at 640135027712

/dev/sdb: isw, "isw_ifbbajief", GROUP, ok, 1250263726 sectors, data@ 0
/dev/sda: isw, "isw_dfdjaigcaf", GROUP, ok, 1250263726 sectors, data@ 0

However, when trying to return to my previous instructions, I got the same errors again when executing $ sudo dmraid -ay

Hope this helps. If I can provide any more information I will be happy to, but I will need fairly explicit directions.
