+#
+# This file contains GC parameters that are loaded when cleaner gets
+# started.  You can force them to be reloaded by sending a HUP signal
+# to the cleaner process.
+#
+# Each parameter is declared with a keyword-value pair or a directive
+# with no argument.  Lines beginning with "#" are ignored.  For
+# details, see the man page of nilfs_cleanerd.conf(5).
+
+# Protection period in second.

+
+# The argument of min_clean_segments and max_clean_segments can be

+# 1000*1000*1000, G 1024*1024*1024, and so on for T, P, E.
