Problem with hard disk and RAID

#1 Post by gwizz »

Hi,

Recently my Debian box's Internet dropped out, so I restarted assuming it would fix whatever caused it. The system complained of a hard disk problem in the next boot suggesting fsck. Now when I boot up I get this which I don't know how to fix:

serial
terminal serial
root (hd0,0)
kernel /vmlinuz-2.6.8-2-386 root=/dev/mapper/mirroreddisk-root ro console=tty0 console=ttyS0
initrd /initrd.img-2.6.8-2-386
boot
-----------

configuration).

I am running LVM and a software RAID1 over the two hdds.

Any suggestions are welcome.
