Thank you for your reply. Then, can I think of it as being able to adjust the time by changing the token in /etc/corosync/corosync.conf? And the site I searched and found was explaining to disable fencing. If so, could you introduce me to a site or blog that explains by activating fencing? I am a college student studying about ha. I first learned about the concept of ha, and I don't know how to set it up or what options to change. And I am using a translator because I am not good at English, but I do not understand how to apply it by looking at the document in the cluster lab. Please check it out. Thank you.
