If the status is File filters...disabled, any filters that have been configured through the GUI (or CLI) for Access Time or Modify Time have been disabled and all files are candidates for data reduction. Specifying the ignore-filters flag enables data reduction on a container with archive data without waiting for the minimum Access Time/Modify Time data-reduction policy.
