Description of problem: It is currently possible to install glusterfs-geo-replication without rsync. My understanding is that geo-replication runs rsync over SSH to sync data. It ends with the following error on the server : [2014-03-20 16:21:37.855513] I [master(/mnt/bricks/brick1/gluster):335:crawlwrap] _GMaster: primary master with volume id c04c8291-f516-45f9-a56b-0ec84bfb89b9 ...

Version-Release number of selected component (if applicable): 3.4.0.59rhs-1.el6rhs.x86_64 How reproducible: 100% Steps to Reproduce: 1. on slave : `rpm -e rsync` 2. start geo-replication 3. Actual results: Fails with the error above. Expected results: It should not be possible to remove rsync RPM without removing glusterfs-geo-replication
