Is it possible to configure heartbeat to trigger a job that would

maintenance script that only runs once a night during a non-peak period.
It assumes that it is running on a server where the database is
available. What I'd like to be able to do is configure heartbeat to
trigger this job once a day, just like crontab is currently doing, but
ONLY on the server where the database is currently running and managed
by heartbeat. I plan on modifying the crontab script to become an
LSB/OCF type script accessible by heartbeat.
Put something like
crm_resource -W -r your_db_resource | grep -qs `uname -n` ||
exit
at the top of your script. Please check the output of crm_resource
beforehand to set this right.

Hello,
Whilst this wouldn't be the usual use for cluster cron, this may be
another option. Configure cluster cron as required and add it as a basic
native resource (fairly simple OCF script available if useful) in the
same group as the service you wish it to be co-located with. Then you
should be able to ensure that any cron jobs run as needed on the same
host as is running the co-located service.
