What Should I Do If a Node Pool Is Abnormal?

Error

The node pool cannot be deleted.

Delete the node pool again. If the node pool still cannot be deleted, submit a service ticket and try to delete it again.

QuotaInsufficient

The node pool cannot be scaled out due to insufficient quota.

Submit a service ticket and increase the quota.

SoldOut

The underlying resources are insufficient.

Update the node pool configuration and select other available resources.

ConfigurationInvalid

The ECS group does not exist (ServerGroupNotExists).

The ECS group to which the node pool belongs is not present. This might be due to manual deletion of the ECS group.

1. Log in to the CCE console. In the navigation pane, choose Nodes. In the right pane, click the Node Pools tab and click the name of the target node pool. Click the Overview tab, click Expand, and check the ECS group to which the node pool belongs.
2. Log in to the ECS console. In the navigation pane, choose Elastic Cloud Server > ECS Group and see if the target ECS group is present.
3. If the ECS group is not present, log in to the CCE console. In the navigation pane, choose Nodes, click the Node Pools tab, locate the row containing the target node pool, and click Update. In the Advanced Settings area, unbind or change the ECS group.

Invalid private image configuration (InvalidPrivateImage):

The private image specified for the node pool requires a minimum disk size (MinDisk) that exceeds the system disk capacity configured for the node pool. As a result, scale-out fails.

Log in to the CCE console. In the navigation pane, choose Nodes, click the Node Pools tab, locate the row containing the target node pool, and click Update. In the Storage Settings area, change the system disk capacity.

InstanceAboveServerGroup

The number of ECSs in the ECS group exceeds the upper limit.

1. Log in to the CCE console. In the navigation pane, choose Nodes. In the right pane, click the Node Pools tab, locate the row containing the target node pool, and click the node pool name. On the page displayed, click the Overview tab, click Expand, and check the ECS group to which the node pool belongs.
2. Log in to the ECS console, choose Elastic Cloud Server > ECS Group in the navigation pane, and check the quota of the target ECS group.
3. If the quota is insufficient, log in to the CCE console. In the navigation pane, choose Nodes, click the Node Pools tab, locate the row containing the target node pool, and click Update. In the Advanced Settings area, unbind or change the ECS group.

InvalidCapacityReservation

A capacity reservation error occurs.

Update the node pool and select other capacity reservation specifications.

MaxNodeCountReached

The number of expected nodes in the current node pool or scaling group has reached the maximum allowed limit.

• Manually add nodes to the node pool or scaling group as needed. If the expected number of nodes in a node pool or scaling group reaches the maximum allowed limit, auto scaling will no longer be triggered for that node pool or scaling group. However, this does not affect manual scale-out operations.
• Choose Nodes in the navigation pane, click the Node Pools tab in the right pane, locate the row containing the target node pool, click Auto Scaling, and change the value of Nodes.

  Or simply disable auto scaling of the node pool or scaling group.

HasAbnormalNode

Some nodes in a node pool or scaling group are abnormal.

• If a node is unavailable, rectify the fault by referring to What Should I Do If a Cluster Is Available But Some Nodes in It Are Unavailable?
• If the node status is incorrect, the deletion may fail. In this case, try deleting the node again.

Insufficient permissions

Insufficient permissions for the cloud server agency. Node pool scale-out is blocked.

1. Log in to the CCE console. In the navigation pane, choose Nodes. Then, click next to the target node pool name to view missing permissions.
2. Log in to the IAM console. In the navigation pane, choose Agencies, locate the cce_admin_trust or CCEServiceAgency agency, and add the missing permissions.
