We run 3.0.4 on ubuntu 9.10 and 10.04 server.
Is there a way to mimic NUFA behaviour?

We are using gluster to store Lucene indexes. Indexes are created
locally from milions of small files and then copied to the storage.
I tried read this little files from gluster but was too slow.
So maybe a NUFA way, e.g. prefer local disk for read, could improve performance.
Let me know :)

At the moment we use dht/replicate:


#CLIENT

volume remote1
 type protocol/client
 option transport-type tcp
 option remote-host zeus
 option remote-subvolume brick
end-volume

volume remote2
 type protocol/client
 option transport-type tcp
 option remote-host hera
 option remote-subvolume brick
end-volume

volume remote3
 type protocol/client
 option transport-type tcp
 option remote-host apollo
 option remote-subvolume brick
end-volume

volume remote4
 type protocol/client
 option transport-type tcp
 option remote-host demetra
 option remote-subvolume brick
end-volume

volume remote5
 type protocol/client
 option transport-type tcp
 option remote-host ade
 option remote-subvolume brick
end-volume

end-volume

### Add io-threads for parallel requisitions
volume iothreads
 type performance/io-threads
 option thread-count 16 # default is 16
 subvolumes quickread
end-volume


#SERVER

volume posix
 type storage/posix
 option directory /data/export
end-volume

volume locks
 type features/locks
 subvolumes posix
end-volume

volume brick
 type performance/io-threads
 option thread-count 8
 subvolumes locks
end-volume

volume server
 type protocol/server
 option transport-type tcp
 option auth.addr.brick.allow *
 subvolumes brick
end-volume
