Raid Problem - Unknown File System Type

[William Colls <william.colls@rogers.com>]

Environment

Kubuntu Linux 10.04.3 LTS
mdadm 2.6.7.1-1ubuntu15

I have two identical disks that were in a raid configuration in another 
machine (also running 10.04). I removed them from the old machine, 
mounted them in a new machine, booted up, and at a terminal prompt as 
root issued

mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdb /dev/sdc

The configuration in the old machine was raid 1.

I checked the contents of /proc/mdstat and it confirmed that md0 was 
indeed running, with 2 devices, as expected. But it also said it was 
resyncing the disks, which I didn't expect.

When the reync completed, I was unable to mount /dev/md0p1. Specifying 
-t ext3 in the mount command gives the error message "wrong fs, bad 
option, bad superblock on /dev/md0p1". Trying mount with no -t gives the 
error "unknown file type linux_raid_member". Looking at the disks with 
Gparted, confims that the system sees the disks, but the filesystem 
shows as unknown.

The output from mdamd --detail /dev/sdb

So - am I truly up the creek without a paddle? Is there any way to 
recover this array? I have backups of most of it, but it will take a 
while to find and restore. And for sure something will be lost.

Thanks for your time.
