Thanks for the response.  When I say mounts don't work I mean that
when I try to mount an exported directory on an older os (most of my
machines are centos 5.7) with a non btrfs kernel I get an "unknown
filesystem" error.  If we can get around this I would be very happy.
    On my NFS exports, I found that I have to set the fsid to something
unique for each subvolume I export. In my case, this prevents all of
the exported filesystems being the same, but it might also help with
your problem.

Good morning btrfs list,
I had written about 2 weeks ago about using extra btrfs space in an
nfs file system setup.  Nfs seems to export the files but the mounts
don't work on older machines without btrfs kernels.
    "The mounts don't work" -- can you be more specific here?

    It would seem that if we can get to the bottom of that problem, you
won't have to muck around with your current set-up at all.
