I haven't used RDMA myself, but from what I saw on irc, I would stick to 3.3.x: 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 improvements 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 (this is from 2013-Jul-16) Pierre-Francois
