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? > - hardware based such as https://www.omzlo.com/articles/the-piwatcher 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. > > Do you have any experience on one of theses two solutions ?
