[Gluster-users] NUFA + replicate

I am using the following config, but replication does not appear to be
taking place between the nodes. If I take down the node the file was
created on, the other nodes can not see it. My only idea is that once
it sees the nufa translator, it does not recognize the other volume
types. If this is so, is there any way to have replication with nufa?

Anyone have thoughts? Config below:

Thanks in advance.
