[pve-devel] training : watchdog not working on 1 server

[Alexandre DERUMIER]

Some news,

I have rollback to ipmi_watchdog, which was not working yesterday,

and It working fine now.

So, indeed, maybe it was an hardware problem. (tests servers are 8-9 years old,so ...)

Thanks for help !

The ipmitool? No, AFAIK these have no build in function to read out the 
softdog status. In fact if I start it on a machine with no hardware dog 
present (only softdog) I get: 
> Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0:

Concluding from the watchdog-mux output the softdog was successfully 
loaded and will (should) also trigger when not reset regularly. 

So the problem is that ipmi gets recognized but the watchdog don't, as 
the other systems are working I still suspect faulty hardware/firmware 
on this one.
