SQLSTATE: None

Description: Only one record exists in the current node group.

Solution: Check whether several information records exist in the current node group.

GAUSS-52612 : " All dilatation nodes do not contain the DN instance."

SQLSTATE: None

Description: All the scale-out nodes cannot contain DNs.

Solution: Check whether the scale-out nodes in the XML file contain DNs.

GAUSS-52613 : " Static configuration is not matched on some nodes. Please handle it first."

SQLSTATE: None

Description: The static configuration file on the node does not match the new XML file.

Solution: Run the preinstall script again.

GAUSS-52614: Timeout. The current cluster status is %s."

SQLSTATE: None

Description: The operation timed out.

Solution: Try again.

GAUSS-52615 : "Cluster lock unlocked due to timeout. "

SQLSTATE: None

Description: Failed to unlock the cluster due to timeout.

Solution: Check whether the cluster status is normal. Check whether the database can write data. View corresponding logs and detailed error information.

GAUSS-52616 : "Can not find a similar instance for [%s %s]. "

SQLSTATE: None

Description: A similar instance [the host name and instance directory] cannot be found.

Solution: Check whether the cluster status is normal and whether the node information in the XML file is correctly configured.

GAUSS-52617 : "Invalid check type. "

SQLSTATE: None

Description: The check type is invalid.

Solution: The check types of the node groups in the scale-out module should be precheck and postcheck. Other check types are incorrect.

GAUSS-52620 : " Not all nodes found. The following is what we found: %s."

SQLSTATE: None

Description: All nodes are not found. The nodes that we found are as follows:

Solution: Check whether the cluster status is normal and whether the configured scale-in node in the XML name is correct.

GAUSS-52623 : "Failed to check node group numbers: Node group numbers is [%d]. "

SQLSTATE: None

Description: The number of the node groups fails to be checked.

Solution: Ensure that the number of node groups is 1 or 2.

GAUSS-52624 : "Failed to check %s node group members: Invalid group name or nodes. "

SQLSTATE: None

Description: Failed to check the members of the %s node group. Invalid group name or node.

Solution: The obtained node group names or the node group members are empty when the node groups are checked during a scale-in. Check whether data in the pgxc_group system catalog is normal.

GAUSS-52626 : "The CN connection on the old nodes are abnormal. "

SQLSTATE: None

Description: The CN connection on the old node is abnormal.

Solution: Check the number of the CN connections on the old nodes of the scale-out module, and ensure that the current number of connections on each CN cannot exceed 90% of the maximum connections.

GAUSS-52627 : " The current cluster is locked."

SQLSTATE: None

Description: The cluster has been locked.

Solution: In the scale-out module, the old node cluster has been locked. Unlock it and continue scaling out the current cluster.

GAUSS-52628 : "Static configuration has already been updated on all nodes, expansion has been completed possibly. "

SQLSTATE: None

Description: The static configuration file has been updated on each node. The scale-in is probably complete.

Solution: Check whether the cluster status is normal after the scale-out. If the cluster includes the scale-out nodes and the cluster status is normal, do not execute any scale-out commands anymore.

GAUSS-52629 : "Cluster ring(%s) can not obtain less than three nodes. "

SQLSTATE: None

Description: The number of cluster rings cannot be less than three.

Solution: Check the XML file configuration in the scale-in scenario to see whether the number of scale-in nodes to be executed is smaller than three.

GAUSS-52630 : "Failed to set the read-only mode parameter for all CN and DN instances. "

SQLSTATE: None

Description: Failed to set the read-only mode for all CNs and DNs.

Solution: Check to ensure gs_guc exists and that the cluster status is normal. Reset the read-only mode again.

GAUSS-52631 : "Invalid value for GUC parameter comm_max_datanode: %s. "

SQLSTATE: None

Description: The value of comm_max_datanode of CNs in the cluster is invalid.

Solution: Set comm_max_datanode to a value greater than the total number of DNs in the cluster.

GAUSS-52632 : "Cluster breakdown or abnormal operation during expanding online, lock process for expansion is lost."

SQLSTATE: None

Description: During online expansion, the cluster breaks down or an abnormal operation is performed. As a result, the lock process for the expansion is lost.

Solution: Call the online expansion operation again.

GAUSS-52633 : "There is no primary datanode."

SQLSTATE: None

Description: The primary DN is not obtained.

Solution: Contact technical support.

GAUSS-52634 : "There is no normal CN and primary DN on local node."

SQLSTATE: None

Description: No normal primary CN or DN has been obtained.

Solution: Contact technical support.
