Seems that things change, but according to the FAQ, there are still some issues with this matter (know how much Space left and use it)
Il still think that mixing réplication (raid) and file system is a very bad idea.
In m'y mind, a snapshot is not a clone. It's just a sort of "diff" of two devices. Something that you can't separate from it's source.
So I dont understand how you can have a filesystem somewhere, and a snapshot of it elsewhere that can be usefull. A copy, yes. Easy. But a snapshot ? Guess there is plenty of things I dont understand about btrfs.
Maybe the first reason for me to not like it :o)
