I'm confused about where you got that it was a raid10? I don't see it in anything he posted, that got here to gmane, at least. In fact, I see only his initial thread-root post, and it doesn't mention raid10 at all that I can see. So given that fi show says two devices, none missing, I'd say it can't be a raid10, and further, given that he didn't specify the raid type, the btrfs default for a two-device btrfs must be assumed, which is raid1 system and metadata, single mode data. But I think that's beside the point in terms of the original question. I think the problem is with his understanding of restore. See the reply directly to his post, that I'll be making after this one. -- Duncan - List replies preferred. No HTML msgs.
