Does it make sense?
well, no. 3.3 isn't tested/packaged for f20. just wondering, if you're looking to avoid os upgrades, rather than keen on latest, why fedora over centos/rhel as engine/nodes?
Thanks in advance
Markus

Being on a current kernel in the hypervisor just gives a better feeling in a 10GBit NFS environment. That comes from several "would-have-been-nice-to-have-that-optimization-option" experiences.
interesting. i assume you mean for the client machines, rather than the NFS server. to learn a bit more on this - do you have some examples of such optimizations which are in latest fedora but not in say, el6.5 kernel? Thanks, Itamar

The feeling is not related to a current comparison but to past situations where a new linux kernel provided some nice feature to squeeze more performance out of the existing infrastructure. We have a lot of SAP test/demo systems that are usually >100GB. Moving data around or (un)loading databases can be quite a headache. Especially with respect to other running systems. Some examples that were helpful in our environment:
- bufferbloat fighting patches (3.6 and on)
- Using SMBv2 client in the kernel (since 3.7). E.g. direct access to a windows share on the hypervisor
- perf patches for better bottleneck analysis
Going with Ovirt and the possibility to do more things online (relocating VMs and their disks) may reduce the requirement for the newest kernel version.
So starting with Fedora 19 on the nodes and a more stable CentOS on the engine could be a good tradeoff. What do you think?
sounds like a plan. though make sure your nodes have same version. I doubt fedora spends too many cycles on things like stress testing say, live migration, between different versions.
If I am not mistaken, the EL6 builds do not support native Gluster, which in his case may be "nice to have". - Thomas
