Subject: Not getting Fencing monitor alerts
To: <[email protected]>
Hi,
I am facing issue in getting pcs alerts for fencing resources.
*Scenario:*
1. Configure the pcs alerts
2. Add stonith resources (resources are unreachable)
3. No monitoring alerts received.
*Note:*
If stonith resources (reachable) are successfully added, then I get pcs
alert for monitor link down and up.
* ------PCS Alert configuration------*
pcs alert create id=${PCS_ALERT_ID} path=/var/lib/pacemaker/pw_alert.sh
pcs alert recipient add ${PCS_ALERT_ID}
value=/var/lib/pacemaker/pw_alert.sh
* ------Starting Stonith------*
my_fence_name="fence-xvm-$my_hostname"
pcs stonith show $my_fence_name
if [ $? -ne 0 ]; then
#monitor on-fail is "ignore" which means "Pretend the resource did
not fail".
#Only alarm will be generated if monitoring link goes down.
pcs stonith create $my_fence_name fence_xvm \
multicast_address=$my_mcast_addr port=$my_hostport \
pcmk_host_list=$my_hostname action=$actionvalue
delay=$my_fence_delay \
op start interval="100s" on-fail="restart" \
op monitor interval="5s" on-fail="ignore"
pcs constraint colocation add $my_fence_name with master
unicloud-master INFINITY
pcs constraint order start $my_fence_name then promote
unicloud-master
pcs stonith update $my_fence_name meta failure-timeout=3s
fi
peer_fence_name="fence-xvm-$peer_hostname"
pcs stonith show $peer_fence_name
if [ $? -ne 0 ]; then
pcs stonith create $peer_fence_name fence_xvm \
multicast_address=$peer_mcast_addr port=$peer_hostport \
pcmk_host_list=$peer_hostname action=$actionvalue
delay=$peer_fence_delay \
op start interval="100s" on-fail="restart" \
op monitor interval="5s" on-fail="ignore"
pcs constraint colocation add $peer_fence_name with master
unicloud-master INFINITY
pcs constraint order start $peer_fence_name then promote
unicloud-master
pcs stonith update $peer_fence_name meta failure-timeout=3s
fi
pcs property set stonith-enabled=true
Thanks,
Rohit
