Use the latest 3.8.x though for doing this process. I remember there was some performance issue with arbtier+sharding which is fixed in latest 3.8.x release.

Also, can we add an arbiter node to the current replica 2 volume without losing data ? if yes, does the re-balance bug "Bug 1440635" affect this process ?

 I remember we had one user in Redhat who wanted to do the same procedure on his production workload with 3.8.x upstream bits and it worked fine. I forget which version it was. Ravi, do you remember?

Looks like 3.8.0 contains the CLI to convert replica 2 to arbiter: http://review.gluster.org/14502
Increasing replica count doesn't trigger rebalance. Self-heal daemon will automatically sync the metadata to the arbiter brick after you add it.
