Remi, sorry for the late reply. Your cluster would be able to work if and only if at least X/2 + 1 servers are up and running and properly connected to the other peers. any server that is restarted will rejoin from scratch. It is very dangerous ! you won't be able to recover and probably it will be very hard to understand what happened (you are going to lose all of your tx logs)
I don't have experience with Kubernetes and non persistent volumes but as far as I know it is not supposed to work Enrico Il giorno ven 11 set 2020 alle ore 14:21 Remi Serrano <[email protected]> ha scritto: > Hello mailing list, > > We are assessing running Zookeeper in Kubernetes.
