Hi, I currently have a replicate DRBD/iSCSI solution running on Ubuntu 13.10. I get great speeds from it, and good fsyncs/sec. What I don't have is snapshot ability, which I really miss from my XenServer days. Using the same hardware and OS, I moved to a DRBD/NFS replicated solution. My speeds dropped dramatically (from 118 MB/s to 35 MB/s), and my fsyncs dropped a bit. The NFS was exported async, and I even tried NFSv4. So, my question is, does anyone have a replicated NFS solution that works well? What about another replicated solution that offers snapshots, and requires only two servers (NAS/SAN) to implement? Gerald ps: I looked at Nas4Free with HAST and NFS, but their NFS does not do async, so speeds are abysmal.
