This task was marked as failed with error in screenshot. Before marking the task “Finished” I did test and it worked on all application servers ie stapp01, stapp02 & stapp03. Also this cron task was set for a root user.
Thanks for reporting this. /etc/crontab file is used to add system wide crons. However in question I believe it is asked to add cron for root user in root user’s crontab itself, hence this was marked as failed.
Please let us know if you still have any confusions.
