I am trying to use GlusterFS as a general purpose NFS file server. I
have tried using the FUSE client but the performance fall off vs NFS
is quite large
Both the client and the server are Ubuntu 14.04.
I am using Gluster 3.6.9 because of the FUSE performance issues that
have been reported with 3.7.8 (see
https://bugzilla.redhat.com/show_bug.cgi?id=1309462)
I am having serious issues with a generic NFS client as shown by the
issues below. Basically most FOPs are giving me a Remote I/O error.
I would not think I was 1st person to see these issues - but my
Google Fu is not working.
Any and all help would be much appreciated
BTW - These operation against a plain Linux NFS server work fine.

Can you please provide the volume configuration(gluster vol info )
and log file for nfs server which u mounted (/var/log/glusterfs)
