[SOLVED] What does the "watchdog-mux.service" ?

[fireon]

Hello,

i'am wondering on some servers, my private one too, the watchdog-mux.service did never start.

systemctl status watchdog-mux.service  
● watchdog-mux.service - Proxmox VE watchdog multiplexer 
 Loaded: loaded (/lib/systemd/system/watchdog-mux.service; static) 
 Active: failed (Result: exit-code) since Mon 2016-06-13 22:17:44 CEST; 6s ago 
 Process: 24311 ExecStart=/usr/sbin/watchdog-mux (code=exited, status=1/FAILURE)
Main PID: 24311 (code=exited, status=1/FAILURE) 

Jun 13 22:17:44 virtu01 watchdog-mux[24311]: watchdog set timeout: Invalid argument 
Jun 13 22:17:44 virtu01 systemd[1]: watchdog-mux.service: main process exited, code=exited, status=1/FAILURE
Jun 13 22:17:44 virtu01 systemd[1]: Unit watchdog-mux.service entered failed state.

What i read is always in combination with clustering and similar. So what is this watchdog really doing.
Can i ignore this?

Thanks an best Regards

This is only required if you run HA services..

 

[fireon]

Ok, but on most other from us servers this service is running fine without HA. Is this depending on something?

Not really. It normally use the softdog kernel module and then access /dev/watchdog. Maybe you load another watchdog driver?

No, everything default from PVE. It is possible that is an special option on the mainboard. I have an Supermicroserverboard.

After add this node to an PVEcluster, the service is starting normaly.
