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

I don't have experience with Kubernetes and non persistent volumes but as
far as I know it is not supposed to work
