Howdy. I just installed my system on software RAID (RAID1 over two discs, twice. I'll elaborate in a minute.), and after coming off the installation I get errors when I try to boot: /dev/md0: The superblock could not be read or does not describe a correct ext2 filesystem. If they device is valid and it really contains an ext2 filesystem (and is not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> /dev/md1: The superblock could not be read or does not describe a correct ext2 filesystem. If they device is valid and it really contains an ext2 filesystem (and is not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> My drives RAID drives are set up as so: sdc1 and sdd1 are mirrored to make md0, sde1 and sdf1 are mirrored to make md1. These are mounted at /mnt/md0 and /mnt/md1, respectively, and formatted to ext4. -- Samuel 'Shardz' Baldwin - staticfree.info/~samuel
