Is there a way to mix RAID 1 and 0 in different subvolumes? I am a new user to btrfs and would like to protect the important files with mirroring, but have a bulk area that is striped for speed and size.

For example I want / and /home to be mirrored, but /media can just be striped as it is all data I can easily recreate.

I see an item in the Project_ideas wiki entry called "Online raid config" which looks exactly like what I am after. I know some of the items in that list are being worked on. Is anyone working on this one?

Thanks

It's certainly on my list of things to look at, if nobody else gets
there first.

Thanks for the info, I'll keep on the lookout for some patches.
