Unhappy Unable to mount Raid1 after reinstalling suse 9.1 ... Please help!


Hello,

I have been messing with linux and trying to learn more for a couple of years now. Here's my situation: I had a perfectly fine suse 9.1 machine with all my important data saved in a software Raid partition /dev/md0. I thought that updating the system to 9.2 won't harm anything. However, after that installation crashed, I had to reinstall 9.1
Now, I cannot mount my /dev/md0
I have been trying for two days! I really appreciate your help!

Here is the output of these commands:
linux:/ # mdadm -D /dev/md0
/dev/md0:

--------------------------------------
From my understanding, this all looks good.
But when I do this, I get:
linux:/ # mount -U 830694B3-FDA3A06E-1BD63051-F9BCE9EF /data1
mount: bad UUID
---------------------------------------
I tried
mount -t ext2 /dev/md0 /data1
mount -t ext3 /dev/md0 /data1
mount -t reiserfs /dev/md0 /data1
but they all failed. I think my filesystem is either reiserfs or ext3, but not sure.

What can I do? I have some important data I need
Thanks for your help!

I noticed that /etc/raidtab does not exist
and I tried:

linux:/ # file -Ls /dev/hda3
/dev/hda3: data

What is data filesystem? And is the missing raidtab the problem?

Thanks
