you should really read some basic documentations

ext4 is a filesystem
btrfs is a filesystem
lvm is NOT a filesystem

you have ext4, btrfs, whatever FS ON TOP of LVM
http://en.wikipedia.org/wiki/Logical_volume_management

for most private environments there is no real benefit of LVM
spread LVM over more than one disk with no RAID under it
is simply dumb becasue if ONE of the disks goes down
you have a problem
