+# Below script has two purposes
+#  1. Display xattr of entire FS tree in a human readable form
+#  2. Display all the directory where contri and size mismatch.
+#      (If there are any directory with contri and size mismatch that are not dirty
+#       then that highlights a propagation issue)
+#  The script takes only one input LOG _FILE generated from the command,
+#  find <brick_path> | xargs  getfattr -d -m. -e hex  > log_gluster_xattr
