            Bug ID: 1421649
           Summary: When using a fuse mount for client, EC volumes do not
                    mount.
           Product: GlusterFS
           Version: mainline
         Component: disperse
          Assignee: bugs at gluster.org

We recently fixed bug 1402661 by using the /usr/libexec/glusterfs folder for
creating the executable files. This folder is created when you have the
glusterfs-server package installed.

However, when you only have the client installed, it doesn't create the
/usr/libexec/glusterfs folder. Therefore, disperse volumes cannot be mounted
correctly. This is from the mount logs on the client.
