EG, /usr/sbin/watchdog-mux is a valid and general watchdog serv= ice, > or better use insted some other services (like 'watchdog' daemon, or > watchdog support bultin in systemd)? >=20 Dow=20you want to make your VM/CT HA? That only works reliably with 3x no= des for quorum (or 2x nodes & qdevice) [0]. But if you want to reset a node if it doesn't spin up a watchdog (doesn't= respond), then you could use systemd watchdog[1]. Though I'd like to add= that resetting nodes continuously (issue is reoccurring), increases the = chances for data corruption.
