检查表以在重新启动CVM之前验证群集运行状况状态

This is a list of health checks to execute prior to the restart to verify cluster health.<\/p>

\u00a0<\/p>

• Verify if any nodes or services are in a 'down' state. Run the following command for smaller sized clusters:<\/li><\/ul>

  \u00a0<\/p>

  nutanix@cvm$ cluster status<\/p>

  \u00a0<\/p>

  • If the cluster contains multiple nodes, running the following command which excludes services that are UP from the output may be more convenient:<\/li><\/ul>

    nutanix@cvm$ cluster status | grep -v UP<\/p>

    • Nodes or services that are unexpectedly in a 'down' state need to be fixed before proceeding with the restart.\u00a0<\/li><\/ul>

      \u00a0<\/p>

      Verify if any nodes are missing or are in a 'down' state in the Cassandra ring. There should be the same number of nodes as the number of IPs in the svmips<\/strong> output (four nodes in the example below). If a node is missing, it means it was removed from the Cassandra ring:<\/p>

      nutanix@cvm$ nodetool -h 0 ring<\/p>

      • Run the following command to check Cassandra status:<\/li><\/ul>

        nutanix@cvm$ ncc health_checks cassandra_checks cassandra_status_check<\/p>

        • Verify if there are any recent FATAL <\/strong>files in the ~nutanix\/data\/logs directory:
          \tnutanix@cvm$ ls -ltr ~\/data\/logs\/*FATAL*
          \tReview any service fatal in the past 1 hour and then validate if the fatal service is in the 'up' state and stable before you proceed with the restart.
          \t\u00a0<\/li>\t
        • Verify if any Stargate node is down or if ha.py<\/em> <\/strong>is enabled.
          \tnutanix@cvm$ ncc health_checks network_checks ha_py_rerouting_check<\/li>\t
        • Verify if the cluster can tolerate a single node failure.<\/li><\/ul>

          nutanix@cvm$ ncli cluster get-domain-fault-tolerance-status type=node<\/strong><\/p>

          • Review any unacknowledged alerts and their create time<\/li><\/ul>
