Mount SATA RAID drives in debian?
 

I have two 160 GB Maxtor SATA-disks attached to a Silicon Image 3112A controller. I'm running the 2.6.5 kernel and have aded support for Silicon Image chip and RAID functionality. When runnig fdisk I can see a /dev/hde device, eaven though fdisk seems to read the partition table wrong.

However, when I try to mount the partitions (FAT32 fs) I get an error msg saying "wrong fs type, bad option, bad superblock on /dev/hde1, or too many mounted filesystems". I used the following command:

mount -t vfat /dev/hde1 /mnt/sata1

help me...

try mount -t auto /dev/hde1 /mnt/sata1, instead of vfat.

nope, got this msg:

"you must specify the filesystem type"

You may want to try another partition. I also use a SATA drive with ntfs on and my C:\ drive is on hde6... Try loading hde2 and if that doesn't work, try hde3 and so on....

Are the drives set up as RAID? If so you need to access the actual RAID devices and not the partitions themselves (i.e. /dev/md? or something to that effect).

hde is the only device I can see using fdisk. The disks are stiped (RAID-0) and therefore visible as one HDD drive (I guess).

This is how it really is:

Partition 1: FAT32, ~10 GB, Windows XP installation, bootable
Partition 2: FAT32, 289 GB, various stuff
Partition 3: FAT32, ~10 GB, various stuff


Fdisk reads the following:

Partition 1: FAT32, ~10 GB, bootable, /dev/hde1
Partition 2: FAT32, ~10 GB, /dev/hde2 (note the order has changed)
Partition 3: Unknown, no size, end block BEFORE the start block.


Håkan; can you tell me more about accessing RAID devices?

You may want to read up on the subject. The Sil3112(a)/3114 is like most onboard UATA/SATA controllers not a "real" RAID device. You may want to look into Thomas Horsten's Medley driver and read this excellent document.

The struggle goes on. I did something to the 2.6.6 kernel config (messed up graphics), so now I run 2.4.26. A happy surprise was that the drivers I need was included in this kernel for the first time. However, when I add support for the Silicon Image 3112 controller, the SATA drives shows up as hda and hdc (even though they are RAID-0, I thought is would be /dev/md0 or something). The normal hda drive (attached to the old primary IDE controller) is gone, and so the kernel is unable to mount root.

I can't find any info about this problem, but it's late and I've studied for 13 hours today so my mind is not the sharpest one in sweden right now...

Final post before bed:

compiled the Silicon Image drive as module instead of static, and so I got a correct mount of the root fs. But "insmod siimage.o" make the SATA disks cause problems with the hda IDE disk still. I get som output telling me that the two SATA disks are identified as /dev/hda and /dev/hdc, and then the fun begins.

The msg "hda irq interrupt" keeps coming up on the screen, and any type of access to any harddrive is impossible. I can use the keyboard, but all I really can to is pull the plug to reboot.
