Hi James, I'm using 3.1.1 on six bricks in dist+replicate all running F14+BTRFS, the clients are on fedora12/13/14. I build the RPMs from source on a F14 machine. The cluster is running entirely on GbE (with some 10Gb lines going in shortly), no RDMA/infiniband so I can't help there. It's gone through a series of looped benchmarks for a while now (from 3.1.0 through a few qa releases) and have so far pushed/pulled over 110TB through it - I'm happy in the stability but not /entirely/ sure of the performance just yet, just started up more testing under 3.1.1. But back to your main question there really isn't enough difference between the near-term releases of Fedora for it to make a huge difference either way. I do think you're better off using the latest Fedora release than an older one that will be end of life soon (f12 tomorrow). Being able to patch/maintain your system is more important than an, often very arbitrary, vendor support list which is usually just an outcome of what people have had time to look into, rather than any measured reason a newer OS isn't supported. Besides the only thing you ever have to /really/ care about is the kernel and glibc major versions, so if it compiles you're pretty much ok (ldd it, that's all it needs).

I know that Gluster Platform uses Fedora 12 as its OS - I was thinking of building my new glusterfs storage servers using Fedora, and was wondering whether Fedora 13 was tested by Gluster for v 3.1.1 and what other people's experiences were. > > One of the reasons for my interest was so that I could use ext4 as the backend file store, instead of ext3. > > Thanks, > > James Burnash, Unix Engineering
