my first raid disaster on reboot :o(

I've got debian 3.1, kernel 2.6 installed on a machine with two 9.1g SCSI
and 4 160g IDE's.

The SCSI is split up into /  /usr  /var  /swap  /tmp  and /home, each set as
a raid1.

The IDE's are set up as raid1 on the ide channels, such that hda is mirrored
with hdc and hdb is mirrored with hdd.

I had to move the system today so powered down with shutdown -h now.

On reboot i just get / mounted ( i think ) and everything else says mdx
corrupt superblock or such and not a valid ext2 fs.

all the mirrors were set us as ext3 and when it was up and running
/proc/mdstat said all was well.

/etc/fstab has all the raids present.


I'm kinda stuck as to where to start.


Could anybody point me in the right direction please.

many thanks

Ken
