Hi Daniel, Thomas,

When I looked back at the docs after reading Daniels email I saw exactly
what your saying Thomas, that its hardware watchdogs only which are
disabled and need to be manually enabled, and that pve-ha-crm has a
software watchdog enabled by default.

Thanks for both your responses and clearing this up for me.
