Hello,
My understanding is that GlusterFS checks with all nodes when
performing a read. Is it possible to just get the data from the node
directly being accessed (in our case using the GlusterFS client),
without consulting with the other nodes?
Our application requires the GFS file to be available, but it's
actually not critical if we end up with an old version of the file in
the case of a server down or net-split etc. Significantly improved
read performance would be desirable instead.
I assume you are talking about replica volumes, in which case the read
does happen from only one of the replica bricks. The client only sends
lookups to all the bricks to figure out which are the good copies. Post
that, the reads themselves are served from only one of the good copies.

Thanks in advance for any help.
