Run cronjob only on one node in cluster

Hi all,

I need migrate soon some www servers from Debian Squeeze to Debian Jessie. The nodes have a cron script which should be running only on one node at the time, this work pretty good with pacemaker and "symlink" resource agent. The problem is: Jessie doesn't have pacemaker in repos [1]

Does anybody knows other working solutions? I'm trying to use "rgmanager + cman + corosync", but configuration and management is not very straightforward and I don't 100% sure if "symlink" RA is compatible with it.

Thanks!
