+# properties.
+# Note: This is to have backward compatibility with 3.3 glusterfs
+#       In the latest releases this dir is present inside .glusterfs of brick.
+# 1) lookup of trash dir fails
+# 2) readdir does not show this directory
+# 3) Self-heal does not do any self-heal of these directories.
