And you lose the feature of protecting your blocks against bitrot! btrfs comes with subvolumes and there is no need to use it on top of LVM. If you want separated /, /usr, /var etc cut yourself subvolumes out of your btrfs-filesystem, as mentioned. forget LVM with btrfs, it's inside already in a way ;-) I use btrfs on at least 3 systems for years now. No problems. OK, it gives a bit of a learning curve. One big pool of storage (depending on how many disks you throw into it), all the subvolumes share the same free blocks ... this may feel scary and strange at first.
