This article mainly explains "how to set the monitoring interval of STONITH resources". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to set the STONITH resource monitoring interval.

With regard to the STONITH resource monitoring interval, the more authoritative documents clearly stated are from the highly available documents of SUSE, while in the configuration examples given by pacemaker, the configured monitor interval time is very short.

You should choose more than 30 minutes, such as external/ipmi, which recommends that the interval is 3600 seconds, so when using external/ipmi to manage STONITH devices, the minimum should be set to 60 minutes.

The SUSE High availability Guide is described as follows:

Note: monitor STONITH resources

Monitor STONITH resources regularly and carefully. For most devices, a monitoring interval of at least 1800 seconds (30 minutes) should be sufficient.

Shielding devices are an integral part of the HA cluster, but the less you need to use them, the better. Power management devices are often affected by excessive broadcast traffic. Some devices cannot handle more than ten or so connections per minute. If two clients try to connect at the same time, some devices will be confused. Most devices cannot handle multiple sessions at the same time.

In most cases, it should be sufficient to check the status of the shielding equipment every few hours. Shielding operations and power switch failures are rare.

At this point, I believe you have a deeper understanding of "how to set the STONITH resource monitoring interval". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
