Proxmox watchdog - how to increase countdown time

[m4rek11]

Hello

I have problem with watchdog coundown time resseting.

I have enabled watchdog by using: https://pve.proxmox.com/wiki/High_A...x#Dell_IDrac_.28module_.22ipmi_watchdog.22.29

I got:
WATCHDOG_MODULE=ipmi_watchdog

The defaults settings are:

Watchdog Timer Use:     SMS/OS (0x44)
Watchdog Timer Is:      Started/Running
Watchdog Timer Actions: Power Cycle (0x03)
Pre-timeout interval:   0 seconds
Timer Expiration Flags: 0x00
Initial Countdown:      10 sec
Present Countdown:      9 sec

I would like to increase the "initial countdown", so I do it by:

ipmiutil wdt -a 1 -t 300

After that, output is:

ipmiutil wdt ver 3.17
-- BMC version 2.65, IPMI version 2.0
wdt data: 44 03 00 00 64 00 60 00
Watchdog timer is started for use with SMS/OS. Logging
               pretimeout is 0 seconds, pre-action is None
               timeout is 10 seconds, counter is 9 seconds
               action is Power cycle
Setting watchdog timer to 300 seconds ...
wdt data: 44 01 00 00 b8 0b b8 0b
Watchdog timer is started for use with SMS/OS. Logging
               pretimeout is 0 seconds, pre-action is None
               timeout is 300 seconds, counter is 300 seconds
               action is Hard Reset

and by command ipmitool mc watchdog get results are:

Watchdog Timer Use:     SMS/OS (0x44)
Watchdog Timer Is:      Started/Running
Watchdog Timer Actions: Hard Reset (0x01)
Pre-timeout interval:   0 seconds
Timer Expiration Flags: 0x00
Initial Countdown:      300 sec
Present Countdown:      299 sec

Time was change - is ok.

But after stop watchdog-mux service, countdown starts from 10 seconds, not from 300 and settigs were reset again do 10 seconds.

So, my question is, how to permanently increase time to 300 seconds?

you can't change it, because HA restart the vm after around 1min.

(so if you force watchdog to 300s, the vm could be started on 2 nodes at the same time with data corruption)

Thank you for your answer.
