at the moment I am testing with 3 nodes that have 4 cores and 16 GB of ram, and all works great. However since DRBD/Linstor have very little overhead compared to other storage products I've tried with Kubernetes, I was wondering whether 2 cores and 8 GB of ram would be sufficient?
Also, if I have three servers with volumes being replicated, how can I avoid downtime when upgrading whenever a new release is out?
