The UUID on the underlying raid devices is different to the filesystem device. eg. /dev/md0 is RAID1 comprised of /dev/sd[a-d]1 /dev/md0: UUID="d046b3c4-8f1b-4c60-8982-9621cf2ac34c" SEC_TYPE="ext2" TYPE="ext3" LABEL="BOOT" /dev/sda1: UUID="bb2b88b1-b1a0-c8f7-2e40-e00de48ff896" TYPE="mdraid" /dev/sdb1: UUID="bb2b88b1-b1a0-c8f7-2e40-e00de48ff896" TYPE="mdraid" /dev/sdc1: UUID="bb2b88b1-b1a0-c8f7-2e40-e00de48ff896" TYPE="mdraid" /dev/sdd1: UUID="bb2b88b1-b1a0-c8f7-2e40-e00de48ff896" TYPE="mdraid" /etc/fstab: UUID=d046b3c4-8f1b-4c60-8982-9621cf2ac34c /boot ext3 defaults 1 2 Regards Clive - Clive Messer <clive@xxxxxxxxxxxxxxxxx> -- 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
