| ISSUE | DESCRIPTION |
|---|---|
| Cluster not starting | Check if the necessary ports (33061, 4567, 4568) are open and not blocked by a firewall. Also, ensure that the cluster nodes can communicate with each other. |
| Node is not joining the cluster | Verify that the node’s configuration file includes the correct cluster address and that the node can resolve the hostname or IP address of the other cluster nodes. |
| Cluster node is in non-primary state | Inspect the cluster status using the ‘SHOW GLOBAL STATUS LIKE ‘wsrep_%” command to identify the reason behind the non-primary state. Common causes include network issues or conflicts with the cluster configuration. |
| Slow performance in cluster | Check the hardware specifications of the nodes to ensure they meet the recommended requirements. Additionally, monitor the cluster status for any signs of network congestion or high load. |
| Data inconsistency between cluster nodes | Validate that all nodes have the same data by comparing checksums or using Percona Toolkit’s ‘pt-table-checksum’ tool. If inconsistencies are found, investigate potential network issues or conflicts during data replication. |
| Cluster node crashes frequently | Review the error logs for any specific error messages related to the crashes. Inspect the hardware, disk space, and memory usage to identify potential resource limitations or faults. |
| Failed SST (State Snapshot Transfer) | Check the SST method configured in the cluster and ensure it is properly set up. Verify that the necessary credentials and permissions are provided for successful SST. Review the error logs for any SST-related errors. |
| Unable to start node after maintenance/upgrades | During maintenance or upgrades, ensure that all necessary steps are followed, such as gracefully stopping the node, taking backups, and validating the cluster status before starting the upgraded node. |
| Incomplete cluster rejoin after node failure | If a node fails and rejoins the cluster, but not all data is replicated, check the error logs for any relevant messages. Use tools like ‘pt-table-sync’ to synchronize the data between nodes. |
| Excessive network traffic in the cluster | Monitor the network traffic using tools like ‘tcpdump’ or Percona Monitoring and Management (PMM) to identify any unexpected or excessive traffic. Investigate the cause, which could be due to inefficient queries or an overloaded node. |
| Cluster node becomes non-operational | Inspect the cluster logs and status to determine the reason behind the non-operational state. This could be caused by hardware failures, network partitions, or conflicts with the cluster configuration. |
| Failed to add new node to the cluster | Ensure that the new node’s configuration matches the existing cluster nodes. Verify that the cluster is in a stable state and that the new node is reachable from the other cluster nodes. |
| Inability to remove a node from the cluster | Check the node’s status and error logs for any specific messages preventing it from being removed. Verify the network connectivity between the nodes and ensure all cluster nodes agree on the removal. |
| Increased latency in cluster operations | Measure the latency using tools like ‘pt-heartbeat’ or PMM to identify any spikes or consistent high latency. Investigate potential network issues, hardware limitations, or inefficient queries. |
| Cluster not handling write-intensive workloads efficiently | Review the cluster configuration, including the number of nodes, hardware specifications, and the workload distribution. Consider optimizing the schema, indexing, or adjusting the Galera-related parameters to improve write performance. |
