#! /bin/bash

#Need to be copied to hooks/<HOOKS_VER>/stop/pre

#TODO: All gluster and samba paths are assumed for fedora like systems.
#Some efforts are required to make it work on other distros.

#The preferred way of creating a smb share of a gluster volume has changed.
#The old method was to create a fuse mount of the volume and share the mount
#point through samba.
#
#New method eliminates the requirement of fuse mount and changes in fstab.
#glusterfs_vfs plugin for samba makes call to libgfapi to access the volume.
#
#This hook script automagically removes shares for volume on every volume stop
#event by removing the volume related entries(if any) in smb.conf file.
