Gluster users - Jan 2010 - Performance Optimization

Hi,

I am new to GlusterFS and I got my first glusterFS-nodes running 2h ago :-)

I am using cluster/replicate on 2 nodes. And I have 4 loadbalanced 
application-servers with apache getting files from glusterfs.

Now I read this site: 
http://www.techforce.com.br/news/linux_blog/glusterfs_tuning_small_files

So my question is:

Is it possible with NUFA to get the apache on the application-nodes to 
do reads from the local disk and writes are replicated to the other 
nodes? And if this is possible, make this sense? And how to build this?

Thank you.
Jan

you can use replicate of two bricks - one brick is on local disk and other
on remote node. You can configure "read-subvolume" option in replicate
to
the brick which is on local disk. This will give you a redundant setup where
reads are served from local disk but writes are sent to both nodes.
