Mounting Raid drives

[JonasZahn]

Hi, I am having the same issue trying to mount a WIN2K drive on a RAID5 box. I am trying to recover the files on a "degraded" logical drive. Here is the output of fdisk, mount, and cat as recommended in post #2. You can see there are 4 physical drives (sda1, sda2, sda3, sda5). I am not sure if I can use Knoppix to recover the files from the RAID5 array or not. --jonas

Seems I started a new thread. The error I am getting when I try to browse to the drive with PCMan File Manager is as follows:

unable to mount device
org.freedesktop.Hal.Device.Volume.UnknownFailure

If I use a terminal to go to /media/sda1 there are no file there. I wouldn't necesssarily expect anything there because sda1 is just one physical drive in the array.

Maybe more background will help.

I have a RAID5 configuration with 4 hard drives (WD 250GB) on an LSI 150-6 RAID controller. Two drives failed (ports 1&2 of 0-3). I replaced the drive at 1 and rebuilt that drive. This shouldn't work--a RAID5 logical drive should not be possible to recover from 2 failed drives. Nonetheless, the logical drive comes up, but as "degraded" as there is still a unresponsive drive on port 2.

I was exploring to see if I could use Knoppix to at least recover the files on the logical drive before spending $1800 to take the 4 drives to the pros to recover the files.

Is the Win2K drive /dev/sda2? I suspect it might be but I am unfamiliar with SFS file systems..and RAID systems. You might be able to mount all the drives if you want to browse them all.

mkdir /media/sda1

mount /dev/sda1 /media/sda1

All your files will be located at /media/sda1
You can do the same for each partition until you hopefully find the one you need. You just need to modify the command for each partition

mkdir /media/sda2

mount /dev/sda2 /media/sda2
