Article DetailsDetailsHelp Details Neo4j has a storeId that uniquely identifies a database store, this should be the same across all instances in the cluster. The storeId ensures that the store is consistent across all of the instances, that is to say they have the same common ancestor and are not different databases with the same name.If you encounter a "Failed to serve TxPullRequest for … storeId xxxxxx because that storeId is different from this machine with Store…" in your $NEO4J_HOME/logs/debug.log similar to: INFO [o.n.c.c.t.TxPullRequestHandler] Failed to serve TxPullRequest for tx 29193 and storeId Store{creationTime:1591347647541, randomId:6812995525063259919, upgradeTime:1591347647541, upgradeId:1} because that storeId is different from this machine with Store {creationTime:1595941375808, randomId:-4448032294085490672, upgradeTime:1595941375808, upgradeId:1} This means that the storeId is different. It can occur if the database has been restored from backup, loaded from a dump, or a neo4j-admin copy operation has been restored.When a Neo4j instance starts, you will notice a line similar to the following entry in the debug.log: INFO [o.n.c.c.s.LocalDatabase] Starting with storeId: Store {creationTime:1582039045717, randomId:4716225943436743213, upgradeTime:1582039045717, upgradeId:1} All instances in a Neo4j Causal Cluster will show a storeId (listed as randomId) entry similar to above in the `debug.log. If the storeId is different for any member of the cluster, the "storeId is different from this machine" error will show up. How do you recover from this mismatch? Identify the instance with the mismatched storeId / randomId in comparison to the other instancesTake an online backup of the database from one of the other "good" instancesStop the instance(s) that has the mismatch randomIdRestore the backup on mismatched instanceOptionally, execute $NEO4j_HOME/bin/neo4j-admin unbind on the mismatched instanceStart Neo4j Please feel free to open a ticket with Neo4j Support, if you have questions about this subject or if you encounter this error.
