[Pacemaker] using ip route change with pacemaker

Hello all,

I've setup two systems using corosync/pacemaker/drbd to use with asterisk.
Everything is running really great so far.

However, I still have to questions:

- I would like to execute two ip route change commands after two virtual
ips were started, before asterisk is started. For this I found a script at
[1], but this doesn't work, because of missing LSB compatibility. Could
someone point me out how to reach this?

- I used this script, didn't work, and after this I deleted it trough crm.
Its not there anymore, but I still got messages like

Failed actions:
fixrouting_monitor_0 (node=asterisk2, call=8, rc=5, status=complete): not
installed
fixrouting_monitor_0 (node=asterisk1, call=8, rc=5, status=complete): not
installed

in crm_mon.

My configuration at the moment:

crm(live)configure# show
node asterisk1 \
	attributes standby="off"
node asterisk2 \
	attributes standby="off"
