Ask how to change the heartbeat time after installing linux ha.

Question

Hello I proceeded with the linux ha installation as shown in the link below.
By the way, I would like to proceed with the test by adjusting the speed of linux ha.
For example, you want to adjust the time that primary and secondary communicate (50ms, 100ms, 150ms, etc.) I'd appreciate it if you could tell me what to do.

Hi,

This is Anne from Windows Cluster team, according to your description, you are setting Linux SQL cluster, Linux SQL cluster's theory is different from Windows Cluster. After some research, I found it seems you may want to set "Corosync" which like heartbeat in Windows Cluster:

https://github.com/corosync

Besides, since we are not familiar with the Linux SQL cluster, we could only provide some related information, for more help, it's recommended to turn to Linux forum.

Thanks for your time!
Best Regards,
Anne
