+         If you say Y here you will be able to repair metadata on a
+         mounted XFS filesystem.  This feature is intended to reduce
+         filesystem downtime by fixing minor problems before they cause the
+         filesystem to go down.  However, it requires that the filesystem be
+         formatted with secondary metadata, such as reverse mappings and inode
+         parent pointers.
+
+         This feature is considered EXPERIMENTAL.  Use with caution!
