A "simple" question regarding RAID 10. When I make a RAID 0 on top of three RAID 1 arrays, should I use "persistent superblock = 1" in that top level array? Won't that confuse the RAID software by putting two different UUIDs on the drives -- one for the RAID 1 arrays and one for the RAID 0 array? As long as I have UUIDs for the three lower level RAID 1 arrays, I should be able to start those arrays with mdadm even if my device ids change. Then shouldn't I be able to start the top level array without a UUID -- just by referring to the mdX numbers? In other words, if md0, md1, md2 start, there shouldn't be any confusion about which are the correct devices to start up md3. Or am I missing something? Appreciate your answers.
