I haven't used RDMA myself, but from what I saw on irc, I would stick to 

16:03 < jclift> RDMA on 3.4 isn't properly working. :(
16:04 < dbruhn> what's not working properly?
16:05 < dbruhn> jclift, I thought there was a ton of effort going into 
3.4 for IB/RDMA
16:05 < jclift> dbruhn: Well, I kept on hitting basic issues when trying 
out distributed+replicated setups.
16:05 < jclift> dbruhn: (With RDMA )
16:05 < jclift> dbruhn: Yeah, there's been a large amount of code 
16:06 < jclift> dbruhn: However, we've hit several bugs with rdma stuff 
when testing, even though the tcp side seemed to not have issues at the 
same point
16:07 < jclift> dbruhn: So, the thought process was pretty much "k, lets 
get 3.4.0 out the door so non-rdma users have some goodness, and we'll 
keep on working on rdma for (hopefully) 3.4.1"
16:07 < dbruhn> jclift, so what is needed for this to move past it?
16:08 < jclift> dbruhn: There are a couple of points to it. Note, this 
is based on my opinion atm... :)
16:08 < jclift> dbruhn: Firstly, we need to get the Gluster Test 
Framework updated so it can test RDMA stuff.
16:09 < jclift> dbruhn: That's in progress, but is kind of blocked by an 
upstream Linux kernel bug, that kernel panics in the fuse module.  Niels 
has a proposed patch to fix it:
16:09 < jclift> dbruhn: https://lkml.org/lkml/2013/7/15/203
