I set up a high availability system with Heartbeat, I wish that when there was a drop in the main cluster and the secondary cluster was activated, Heartbeat start in it and execute a shell script.

  • Contents of /etc/ha.d/haresources

    master IPaddr::10.0.0.1/24 test.sh

  • Contents of /etc/ha.d/ha.cf

    autojoin none
debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility local0
ucast ens32 10.0.0.3 
ucast ens32 10.0.0.2
udpport 694 
use_logd yes
keepalive 1
deadtime 10
warntime 5
initdead 20
node master
node slave
auto_failback on

I gave execute permission to the script and put it in the path /etc/init.d/, but I still could not get it executed through Heartbeat, is this type of procedure possible?

  • Oh, whoops. You're using Heartbeat v1 (haresources) which is ancient. Consider using Pacemaker with Heartbeat, or even better, Pacemaker with Corosync. You're not going to find many resources online for Heartbeat v1. – Matt Kereczman Aug 23 '18 at 16:44

There are quite a few different ways you might achieve that.

You could put a script in /etc/init.d/ but you'll need to make sure it's LSB compliant: http://www.linux-ha.org/wiki/LSB_Resource_Agents

You could write an OCF resource agent for Pacemaker: http://www.linux-ha.org/doc/dev-guides/ra-dev-guide.html

Or you could try using the ocf:heartbeat:anything resource agent. It can run an arbitrary command, but there is setup/requirements involved with it. Run the following command on one of you nodes to learn more: # crm ra info ocf:heartbeat:anything
