+# This is a template script which can be used to migrate the GlusterFS
+# storage infrastructure from 'cluster/unify' to 'cluster/distribute'
+
+# This script needs to be executed on the machine where namespace volume 
+# of 'cluster/unify' translator resides. And also, one need to mount the 
+# new 'cluster/distribute' volume with "option lookup-unhashed yes" on 
+# the same machine.
+# If the namespace volume was replicated (ie, afr'ed), then this can be 
+# executed just on one of the namespace machines..
+
+# Only the variables defined below needs to be changed to appropriate path
+
+# This is export from old 'cluster/unify' volume's namespace volume.
