I was trying to add a previously created raid5 array with: mdadm --add-journal /dev/md3 /dev/sdc That gave an error though: "/dev/md3 does not support journal device /dev/sdc". I'm guessing that happens because the initial array was created without journal support? Is there anything I can do to get this to work without recreating the entire array? -- 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
