[doc] Issue in "Monitoring fencing devices"
Last modified: 2024-07-18 00:11:05 UTC
Monitoring fencing devices: https://documentation.suse.com/sle-ha/15-SP5/html/SLE-HA-all/cha-ha-fencing.html#sec-ha-fencing-monitor As discussed monitoring of fence-agent does not make sence. Please adapt documentation in this regard. Do not forget this must be changed for all SLES versions. Also SLE12-SP5 has this text: https://documentation.suse.com/sle-ha/12-SP5/html/SLE-HA-all/cha-ha-fencing.html#sec-ha-fencing-monitor
Thanks Peter, I've added this to our queue. Could you please elaborate on what was discussed? I agree that this section is a bit odd and needs an update, but more context would be helpful.
Hi Lars, Thanks for the clarifications. I've also got another question about a contradiction in this section. In one paragraph, it says: --- Monitor STONITH resources regularly, yet sparingly. For most devices a monitoring interval of at least 1800 seconds (30 minutes) should suffice. --- But a few paragraphs later, it says: --- Checking the status of fencing devices once every few hours should be enough. --- Which of these intervals should we recommend?

Hi Tahlia, in fact the monitoring interval depends on the device and the infrastructure. For sbd rescources the monitor is pointless at all. So you may change the sentence to: "For most devices a monitoring interval of 1800 seconds (30 minutes) or more should suffice. The exact value depends on device and infrastructure. Stonith SBD resources do not need a monitor at all." Regards, Lars

Thanks, Lars
Thanks Lars! This is now complete and backported, and will be published with the next weekly docs update.
