Anyone using a replicated NFS storage system?

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.

..what about using a ZFS based NAS/Filer with iSCSI?
Use ZFS-Volumes on the NAS and export these as targets via iSCSI.
ZFS will give you the ability to snapshot the targets this way.

ZFS may be a solution, although I have a manager that would never grasp the concept of non-gui based snapshots.

How does ZFS run on top of DRBD? I did both XFS and EXT4 exported via NFS on top of DRBD, and the speeds dropped dramatically (118 MB/s iSCSI to 35 MB/s async NFS)
