this is possible, but changing sanlock timeouts can be very tricky and can have unwanted/unexpected consequences, so be very careful. Here is a guideline how to do it:

Thank you for your feedback, this seems to be exactly what is happening. After reading the doc, my gut feeling tells me it would be smarter to shut down our VMs, go into maintenance mode and then perform any switch upgrades/reboots instead of trying to tweak the timeouts to survive a possible 3min+ reboot. We don't have any serious uptime requirements so this seems like the easiest and safest way forward. Best regards, cen
