+++ This bug was initially created as a clone of Bug #851960 +++ use libgfapi instead of doing a FUSE mount. This helps greatly as we are not restricted with FUSE limits.
Since Geo-replication uses Rsync for syncing only delta changes and Tar as sync_engine for syncing small files. We are not planning to use libgfapi unless rsync/tar supports libgfapi. Please reopen this bug if this feature is required.
