Hi Shravan,
Your monitor operation is always returning OCF_SUCCESS, which will tell
Pacemaker it's always running, always.
Try something like this in your RA:
monitor_()
{
touch /monitor
if [ -f "/start" ]; then
return $OCF_SUCCESS
fi
return $OCF_NOT_RUNNING
}
And in your stop operation, remove the 'start' file to indicate your resource
is not running:
stop_()
{
rm /start
return $OCF_SUCCESS
}

Subject: [Pacemaker] resource's start/stop not getting called
Hello guys,
I'm little confused here.
My resource's start or stop is not getting called or so I understand
because of the behavior I see based on my script.
But monitor operation is getting called.
My resource agent called "safe" is only getting called by pacemaker
when monitoring but not for starting or stopping.
I only see /monitor file getting created and not /start or /stop files.
For now, temporarily I have my do-nothing script located here :
/usr/lib/oc/resource.d/pacemaker/safe
The contents of which are :
======================
#!/bin/sh
# initialization
. ${OCF_ROOT}/resource.d/heartbeat/.ocf-shellfuncs
usage_()
{
return $OCF_SUCCESS
}
isrunning_safe()
{
return $OCF_SUCCESS
}
monitor_()
{
touch /monitor
return $OCF_SUCCESS
}
start_()
{
touch /start
monitor_
if [ $? = $OCF_SUCCESS ]; then
return $OCF_SUCCESS
fi
return $OCF_SUCCESS
}
stop_()
{
touch /stop
return $OCF_SUCCESS
}
status_()
{
monitor_
if [ $? = $OCF_SUCCESS ]; then
return $OCF_SUCCESS
fi
}
metadata()
{
return $OCF_SUCCESS
}
validate_all_()
{
return $OCF_SUCCESS
}
