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:

type protocol/client
option transport-type tcp
option remote-host zeus
