Hi,
It seems that you are using pcs 0.9.x. That is an old and unmaintained
version. I really recommend updating it.
I can see that you disabled stonith. This is really a bad practice.
Cluster cannot and will not function properly without working stonith.
What makes you think nodes are communicating only every 30 seconds and
not often? Setting 'monitor interval=30s' certainly doesn't do such thing.
Regards,
Tomas

Hello.
I installed linux ha on raspberry pi as below.
1) 1) sudo apt-get install pacemaker pcs fence-agents resource-agents
2) Host Settings
3) 3) sudo reboot
4) 4) sudo passwd hacluster
5) 5) sudo systemctl enable pcsd, sudo systemctl start pcsd, sudo
systemctl enable pacemaker
6) 6) sudo pcs cluster destroy
7) 7) sudo pcs cluster auth <node1> <node2> -u hacluster -p <password
for hacluster>
8) 8) sudo pcs cluster setup --name <clusterName> <node1> <node2>
9) 9) sudo pcs cluster start —all, sudo pcs cluster enable —all
10) sudo pcs property set stonith-enabled=false
11) sudo pcs status
12) sudo pcs resource create Virtual IP ocf:heartbeat:IPaddr2
ip=<address> cidr_netmask=24op monitor interval=30s
So, I've set it up like this way.
By the way, is it correct that node1 and node2 communicate every 30
seconds and node2 will notice after 30 seconds when node1 dies?
Or do we communicate every few seconds?
And can node1 and node2 reduce communication time?
What I want is node1 and node2 to communicate every 10 ms and switch as
fast as possible.
Please answer.
Thank you.
