Not an answer to that specific question, rather a "why even bother" suggestion: You say: > > two nodes active/passive and fetchmail as cronjob shall run on active only. How do you know the node is "active"? Maybe some specific file system is mounted? Great. You have files and directories which are only visible on an "active" node. Why not prefix your cron job lines with test -e /this/file/only/visible/on/active || exit 0; real cron command follows or cd /some/dir/only/on/active || exit 0; real cron command or a wrapper, if that looks too ugly only-on-active real cron command /bin/only-on-active: #!/bin/sh same-active-test-as-above || exit 0 "$@" # do the real cron command Lars > 2013/7/5 andreas graeper <agrae...@googlemail.com> > > > hi, > > two nodes active/passive and fetchmail as cronjob shall run on active only. > > > > i use ocf:heartbeat:symlink to move / rename > > > > /etc/cron.d/jobs <> /etc/cron.d/jobs.disable > > > > i read anywhere crond ignores files with dot. > > > > but new experience: crond needs to restarted or signalled. > > > > how this is done best within pacemaker ? > > is clone for me ? > > > > > > thanks in advance > > andreas -- : Lars Ellenberg : LINBIT | Your Way to High Availability : DRBD/HA support and consulting http://www.linbit.com DRBD® and LINBIT® are registered trademarks of LINBIT, Austria. _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
