Hi, What I forgot is to put in a check if the cluster is already activated and do not do activation. If you don't activate the first time then the cluster will remain in an inactive state and will not process requests to store/read data: https://ignite.apache.org/docs/latest/clustering/baseline-topology
Try using the control script to set the baseline topology: https://ignite.apache.org/docs/latest/tools/control-script#adding-nodes-to-baseline-topology In your particular case, there is corruption in your metastorage. Metastorage is data used to keep cluster meta information(details about cluster config, operations, cache setup, etc) Two nodes have different data in their metastore, and this is not allowed. It is likely you changed baseline topology incorrectly. Read through both links above to make sure the steps followed are as specified. If you are able to reproduce it, send a list of steps to do so, the code you use to set the baseline topology, your Ignite config, and possibly a code reproducer.
