I don't believe there's a raid10 personality. What you would do is build your 2 stripe sets, then mirror those striped md's...
Actually, you have it backwards. Build 2 separate mirror sets, then make a stripe set of those 2 mirrors. Here's why: In your setup, if one drive fails, that whole stripe set is down for the count. You're then running on only 2 drives, no redundancy. The other way, if one drive goes, the other drive in that mirror set keeps going; you're still using 3 drives. Hopefully I explained it clearly... :)
