Uh, BTRFS and Lustre can't easily be compared. The former is exclusively a single-host fs, the latter is a cluster-only fs. The former focuses (more or less successfully) on data resilience and availability, the latter on performance. There are quite a few large scale distributed file systems. XtreemFS, Hadoop and Ceph come to mind. There are others, e.g. OrangeFS (successor of PVFS), PanFS, etc. .
