dmraid activates nvidia Fakeraid with missing disk

[root_tux_linux]

Hi, again me, ;)

I've 3 S-ATA HDD in my PC and i use this HDD's with nvidia fakeRAID (Raid0)

ubuntu@ubuntu:~$ sudo dmraid -b
/dev/sda: 625142448 total, "S0MQJ1DQ203428"
/dev/sdb: 625142448 total, "S0MQJ9CQ205588"
/dev/sdc: 625142448 total, "S0MQJ1FP800479"

Each HDD has 320GB. 3x 320GB = 960GB

And here is the problem.

dmraid + Ubuntu can find only 2 HDD's!

ubuntu@ubuntu:~$ sudo dmraid -r
/dev/sdb: nvidia, "nvidia_ecbcchff", stripe, ok, 625142446 sectors, data@ 0
/dev/sda: nvidia, "nvidia_ecbcchff", stripe, ok, 625142446 sectors, data@ 0
ubuntu@ubuntu:~$

Disk /dev/mapper/nvidia_ecbcchff: 640.1 GB, 640145817600 bytes
255 heads, 63 sectors/track, 77826 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

                      Device Boot Start End Blocks Id System
/dev/mapper/nvidia_ecbcchff1 * 1 58005 465920000 7 HPFS/NTFS

Command (m for help):

My Raid works with Windows XP, Gentoo and Arch Linux! (I can show you a Pic).

I had the same Problem with 8.04 (https://bugs.launchpad.net/ubuntu/+source/dmraid/+bug/254923).

I marked your original bug as a duplicate since it is caused by your bios making use of the Host Protected Area. Take a look at the dup bug report for suggested workarounds. You appear to have a second issue though, which is that dmraid is going ahead and activating the array anyway even though it is missing a disk. This should not be happening. Please post the files generated by dmraid -rD.

[John B. Anderson (johnbanderson)]

I believe I have a similar issue, except dmraid does not activate the array. I've read a number of similar bugs, so I'll attach the outputs that I think might be useful:

Oh, I'm trying to install Jaunty using the FakeRaidHowTo. Blocked on step 4d: sudo dmraid -ay

[Danny Wood (danwood76)]

John this is not a forum.

It looks as though you have not built the array properly with the BIOS utility.
Also you could have formatted the /dev/sdb to something else and erased the metadata.

Try rebuilding the array and repartitioning.

[John B. Anderson (johnbanderson)]

Indeed, I've seen this same bug many times on a number of forums (ubuntuforums in particular), and none of them have any idea what to do with it. I believe that this is a bug for the reasons mentioned below. If you think this is a different bug than the one I've commented on, please advise me to file a new one.

I have rebuilt the array multiple times (with 2 disks, there's only one way to do it on an ICH10R, as far as I can tell), and tried to install Jaunty on both a virgin array and after a Windows 7 installation. Windows hasn't had any difficulty recognizing the array, leading me to believe that this is a bug in the production version of dmraid (though I've tried a few older versions without success).

I'm not aware of any method of partitioning an unrecognized array.

[Danny Wood (danwood76)]

Ah right may I point you to this bug:
https://bugs.launchpad.net/ubuntu/+source/dmraid/+bug/372170

and also:
https://bugs.launchpad.net/bugs/219393

It could be to do with the HPA, there is a workaround in those bug reports:

This bug hasn't been updated for quite some time. Can you tell us if this is an issue for you in Maverick 10.10 please? Thank you.
