Re: Local node is not added in baseline topology

Hello! You can use control.sh. It can look up nodes as well as add them to baseline. Unfortunately I did not see your commands so I can't know for sure. I'm not sure that auto-adjust will work for nodes added prior to enabling it. Regards, -- Ilya Kasnacheev чт, 13 авг. 2020 г. в 10:17

Re: Local node is not included in Baseline Topology and will not be used for data storage. Use control.(sh|bat) script or IgniteCluster interface to include the node to Baseline Topology.

Hello! This happened because you activated the cluster before this server node was added to it. Once you do, you need to add nodes to baseline manually or use auto-adjust. I'm not sure there's a C++ API for activation/baseline changes. You can use control.sh for that. Regards, -- Ilya
