Hi Pierre-Francois,
I am running 6 RPI4s with fedora 37. K3S is powering this cluster and
it
is working well :)
But from time to time, 1 RPI is randomly hanging.
I am thinking about implementing a watchdog :
- software based, using embeded linux kernel
If the RPi itself is locking up I'm not sure how a SW based approach
would work, how would it trigger if the kernel isn't working? Also not
sure what you mean here but "embeded linux kernel", care to explain
some more?
The RPI4 already has a HW watchdog onboard, the driver is bcm2835_wdt,
maybe you could start by investigating the use of the Linux watchfog
stack with that. systemd has support for HW WDTs and we enable all the
pieces in Fedora already, I suspect that will be a good start for you.
