During the installation, deployment, and maintenance of the GBase database (GBase数据库), some error messages may be overly verbose or unclear, making it difficult to troubleshoot. Additionally, improper operations can cause cluster abnormalities.
This article summarizes some GBase 8c issue cases and solutions for sharing. If you encounter additional problems, please feel free to reach out to the relevant technical support personnel.
Issue 1: Dependency Causes Deployment Failure
Error Message:
Error Analysis:
The error message indicates that the port is occupied, but upon investigation, no processes are actually using the configured port.
Solution:
The hostnames of multiple machines are the same. Changing each machine to a unique hostname resolves the issue, allowing installation and deployment to complete successfully.
Issue 3: Component Status Abnormality
Error Symptom:
Some nodes fail to start normally and are in a "dropping" state, for example:
Preliminary Steps:
After restarting the node_1 machine in the DCS, certain components show abnormal statuses.
Problem Analysis:
An abnormal etcd state impacts the synchronization of information among components, indicating an issue with the etcd component.
Solution:
Upon investigation, it was found that the firewall re-enabled after the machine restarted, causing cluster state abnormalities. Disabling the firewall resolved the issue, restoring normal cluster operations.
Summary
This article covers issues related to dependencies, ports, and component abnormalities. For other potential issues that may arise during GBase database (GBase数据库) deployment and usage, feel free to share in the comments.
