Thanks, Dave richardjhMarch 8th, 2010, 11:10 PMIt looks like the raid devices are already assembled, which makes it a bit easier. hooked the linux drives back to the system and booted linux, no problems.

If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck The Superblock Could Not Be Read Or Does Not Describe A Correct Ext2 Finally, restore the superblock from the backup, again replacing the x's with your partition name, and block_number with the first backup superblock. Next, do a raid 0, see if you get the same issue.

Nice huh? after all, for a small user like me, I feld it was quiet a complex thingy to do :-)Keep you guys informed ! The superblock contains all the critical information for the filesystem to function. cat /proc/mounts lists a line "/dev/md0 /mnt/md0 ext3 rw 0 0" 10.
