Can the linux package "watchdog" (or similar software) utilize any real hardware watchdog devices on DigitalOcean droplets?
I’m looking into high-availability clustering for various services and fencing/STONITH is a topic that comes up often. One key component to this in a virtualized environment is hardware watchdogs, which are the only way to reliably fence a production environment.
Are there any such hardware watchdog devices available to any currently available DO droplet types? for example, something that can be utilized with the ‘watchdog’ software package mentioned here: https://wiki.clusterlabs.org/wiki/Using_SBD_with_Pacemaker
