I have found the following and see that you can convert from raid4 to raid0 fairly easy http://ubuntuforums.org/showpost.php?p=10412231&postcount=20 i have a 2 disk raid5 and want to be able to convert this to raid0, i was thinking of adding a extra 2 disk and setting them up as raid0, moving the data over then adding the original raid5 disks to the raid0 setup, but i see that you are unable to add disk to a raid0 setup, would it be possible to setup a raid4 with 2 disks and 1 missing, move the data from the raid5 to raid4 then add both of the original disks to the raid4 the downgrade this to raid0??? -- 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
