That should be doable. If you want a raid-1+0, create two 3-drive raid-0s, and then create a raid-1 over the top. That will give you 3 raid arrays to manage at the linux level :-( I don't know the syntax off the top of my head, but telling mdadm to create a raid-10 with two mirrors should be pretty easy, then it's just the one raid to manage. Look at the raid wiki. This page in particular has an explanation of raid-10 and raid-1+0 https://raid.wiki.kernel.org/index.php/What_is_RAID_and_why_should_you_want_it%3F Note in particular that certain variants of raid-10 can *not* be explanded, so if you decide you want a bigger raid you're stuck with creating the new raid then moving the old one across.
