Crontab entry LTM Version 15.x not running

Hi @all,

I updated out LTM BIG-IP VE from Ver. 13.x to 15.x.

But now my cron entry for backup the Certs and ucs files are not running anymore.

In Ver. 13 I had a file located under /etc/cron.d/f5backup with the following content:

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=test@abc.de
HOME=/var/tmp
2 0 * * * root /bin/bash /root/create_backup_bigip_v11.sh 1>/var/tmp/create_backup.log 2>&1

But on Ver. 15.x the cronjob is not running

Also an entry with crontab -e is not working

2 0 * * * /root/create_backup_bigip_v11.sh

Someone an idea?

BIG-IP
cron
crontab

    Does the crond service run? Try: systemctl status crond

    What does logging show? Try: journalctl -u crond.service

      Hi Nils, ups you are right the cron was not running ☹ But where should I put my cronjob? In the /etc/cron.d directory like in Ver. 13.x or directly in the crontab? Another question, how setup the cron daemon to run at startup? Thanks for the hint about cron running or not ☺ Joern Von: DevCentral Community Antworten an: Reply to DevCentral <0-1uqb5lh5rbnjoh.1rs1y8b7vmj96b5p.v837wuo38g2obvbt@m59xqeapnfh7v5nz.sylntfjh1l1263lb.0-hxqveae.na84.chatter.salesforce.com> Datum: Dienstag, 7.

        Hi Joern,

         

        The crond should be started automaticaly. You can verify if it is enabled with the command 'systemctl status crond.service'. For example see the image below, and notice the 2nd line. The crond.service is enabled, and the vendor preset is enabled.

         

        It seems that you can use the /etc/cron.d directory or the root crontab directly.
