can't mount raid 5 after installation
Hi all
I'm installing a debian server with 4 sata drive on A8V motherboard.
My system is on a 40 go ide hard disk and i've created a raid 5 during
installation for my /home with the 4 sata drive.
After reboot, i got this :
# cat /etc/fstab | grep /home
/dev/md0 /home xfs defaults 0 2
# cat /etc/mdadm/mdadm.conf
DEVICE partitions
ARRAY /dev/md0 level=raid5 num-devices=4

# mount /dev/md0
mount: /dev/md0: can't read superblock
I have the same error (bad superblock) with reiserfs or ext3 fs on /home.
So does any one know why can't i mount my /home and why do i have that
kind of error ?
I don't know how where to check for that superblock problem.
Thanks.
Ps : i have installed raidtools2 and raidutils
