Thu, 22 Jun 2017 15:04:42 +0000 (UTC) X-Virus-Scanned: ClamAV using ClamSMTP The device-mapper features "queue_if_no_path" and "retain_attached_hw_handler" should be set via the configuration keywords "no_path_retry" and "retain_attached_hw_handler", respectively, not via "features". Print a warning if these "features" settings are encountered. So far these "features" settings will only be ignored if the respective other keyword is set, so in particular 'features "1 queue_if_no_path"' will still work as expected, but cause the warning to be printed. We should consider ignoring these completely in a future version.
