Hi
I am currently a little confused when it comes to UnionFS I have a build already. Currently now I have some drives mirrored with btrfs if I where to use UnionFS is there any point in using mirrored then. Would I not get more space and get more out of using UnionFS in general because as far as I understand if one drive goes dead like 1 3TB drive then the data will still be on the UnionFS filesystem.
