Ho to all ... And thanks in advance for any help ..
I have a running 5 node pve 2.3 cluster . To upgrade to 3.0, the how-to advises to make a backup of all config beforehand . But, in a cluster, all config files are replicated in all nodes, correct ? So, if something goes wrong in upgrade, all I need to do is reinstall that node from scratch and reconnect to the running cluster ... Am I wright ??? And. if something indeed goes wrong, I can install PVE 3.0 and reconnect to running 2.3 cluster, or I MUST reinstall 2.3 ? Just looking for best practices .... Fábio Rabelo
