to expand the array :)
I haven't had problems doing it this way yet.
I finally figured out my mistake creating the raid devices and got a working RAID 0 on two RAID 1 arrays. But I wasn't able to add another RAID 1 component to the array with the error
mdadm: add new device failed for /dev/md/mdr1_3 as 2: Invalid argument
Googling up this indicates that it's the expected result trying to add a new device to a RAID 0 array. Could you or anybody else please share what's the trick to achieving this?
