[Gluster-devel] NFS reexport

[Amar S. Tumballi]

Hi Richard,
 Yes, you can't directly use the 1FreeBSD server as glusterfsd server yet.
But your idea is perfect, you can export the FreeBSD server's disk using
NFS. and in the server where you have Linux, use it as a posix translator.

Assume you have

/mnt/usb1 <- first USB disk
/mnt/usb2 <- second USB disk
/mnt/freebsd <- NFS exported freebsd partition.

now your server config will look like

----
volume usb1
  type storage/posix
  directory /mnt/usb1
end-volume

volume usb2
  type storage/posix
  directory /mnt/usb2
end-volume

volume nfs
  type storage/posix
  directory /mnt/freebsd
end-volume

volume unify
  type cluster/unify
  subvolumes nfs usb1 usb2
  option namespace ns
  option scheduler rr
end-volume

volume server
...
  option auth.ip.unify.allow *
end-volume

------

Now you can have a client spec with just a client protocol, which connects
to unify ("option remote-subvolume unify")
