Hello. The cluster support is unmaintained for years and can have any issues.
Here you need to add -ifNotExists parameters to your TCP servers and make sure they aren't available outside of your network, because combination of -tcpAllowOthers with -ifNotExists effectively creates a remote security hole in your system; everyone who can connect to your server can execute any commands on it. After initialization of cluster it would be better to restart its nodes without this additional parameter for more safety. Current behavior looks like a bug. I filled a new issue about it: https://github.com/h2database/h2database/issues/2974 -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
