I use mdadm, not mkraid, but it appears the problem is right there: "/dev/hda1 is mounted". Probably if you have a mounted filesystem on /dev/hda1, you cannot add it to the raid array. Once you've created the raid array you can mount /dev/md0 instead of /dev/hda1. -Steve - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
