The best way to export a volume over Samba is with the vfs_glusterfs
plugin. This improves performance and is not affected by any of the FUSE
mount restrictions.

In your case, a configuration snippet would look like this:

    [gfsvol]
    comment = Gluster share of volume gfsvol
    path = /
    read only = No
    guest ok = Yes
    kernel share modes = No
    vfs objects = glusterfs
    glusterfs:loglevel = 7
    glusterfs:logfile = /var/log/samba/glusterfs-gfsvol.log
    glusterfs:volume = gfsvol

The "vfs object" for GlusterFS is provided by the samba-vfs-glusterfs
package on Fedora and other RPM-based distributions. The needed packages
are also available here:

This information comes from the following blog by Lala:
