[Gluster-users] gluster client problems

My only suggestion upon reading your client file is to remove the #commented lines in the translator section for volume writebehind and all of the commented out stat-prefetch and try that configuration. The fact that the comments "shouldn't" matter does not necessarily mean that they don't.

Also - do make sure to push the changed client volfile out to all the clients and restart them - unless you're using the method of accessing a centralized volfile.
