So now md0 contains the same thing > as hda1. in fact, to check the size I was using 'fdisk -l' because it gives size in bytes (not in blocks), like this: backup:~# fdisk -l /dev/md0 Disk /dev/md0: 1003 MB, 1003356160 bytes And the same for /dev/hda1 But that's a detail, just so you know that I dd'ed my root partition correctly and I can mount /dev/md0 without problems. -- Janek Kozicki | - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
