[ovirt-users] Question on gluster sharding maturity/stability

I'm currently running oVirt 4.1 (with gluster 3.8.15) and as this is a cluster which has been upgraded from (I believe) oVirt 3.5 originally, the storage volumes use old "Optimize for Virt Store" configuration of not enabling sharding. I see now that the oVirt 4.1 "optimize" configuration does enable sharding, but I am a bit wary after seeing some horror stories from about a year ago about corruptions and data loss caused by sharding in earlier gluster versions. Is the gluster associated with oVirt 4.1 now at a stable point that I can and should trust sharding? I plan on doing some simple experimenting first, but I see a great benefit to balancing distributed-replicated volumes and for healing times and I would like to take advantage of these benefits now. Since the ovirt engine is now 'recommending' the use of sharding for disk store volumes, this leads me to believe that it is trusted by the oVirt crew. Does this seem accurate?
