+#The preferred way of creating a smb share of a gluster volume has changed.

+#New method eliminates the requirement of fuse mount and changes in fstab.

+#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.
