Title: Mounting one of the raid discs via a USB caddy
Post by: brianr on July 20, 2006, 11:10:30 AM: I am trying to mount a hard disc that has been created as one of a raid pair, by putting it into a USB caddy.

The system I am mounting and the original system are both identical SME7 installs with no extras.

On boot up the kernel sees both partions as sda1 and sda2, and I create mount points for each of them, but it will only allow me to mount sda1 (which appears to be the boot partition). Mounting sda2 gives me this:

Code: [Select]
root@testserver ~]# mount -t ext3 /dev/sda2 /media/usbdisk2 mount: wrong fs type, bad option, bad superblock on /dev/sda2, or too many mounted file systems

Is this to do with the logical volume stuff?

Predictably it is the partition with the data that I want!!

fdisk shows the two partitions fine.

Code: [Select]
Disk /dev/sda: 122.9 GB, 122942324736 bytes 255 heads, 63 sectors/track, 14946 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 fd Linux raid autodetect /dev/sda2 14 14946 119949322+ fd Linux raid autodetect

Any ideas?

Use Knoppix?

Actually trying knoppix might give me a handle on the problem..

Code: [Select]
mount /dev/mapper/main-root /someplace/somewhere

I have no idea if this can be done on a raid setup since the device already exists and is mounted.
