i'm not sure exactly what i did wrong and i wouldn't mind starting over only i'm not sure how. i created a raid level 1 array using 2 disks. mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda /dev/sdc then i realized i was supposed to partition these hard drives before creating the array. so i stopped the array after creation was complete, mdadm --stop /dev/md0 and partitioned the hard drives for linux raid auto 'fd'. i only put one partition on each hard drive. then i tried to assemble the array like this: mdadm --assemble /dev/md0 /dev/sda1 /dev/sdc1 but i get these errors: mdadm: metadata format 00.90 unknown, ignored. mdadm: cannot open device /dev/sda1: No such file or directory mdadm: /dev/sda1 has no superblock - assembly aborted i'm not sure what to do from here... can someone help?? -- 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
