What Do I do if the Scale-in Button Is Dimmed?
Symptom
When a user performs a scale-in operation, the Scale In button is unavailable and the user cannot proceed to the next scale-in operation.
Possible Causes
The system verifies the cluster's eligibility for scaling in before each operation. The Scale In button is dimmed if the cluster does not qualify.
Solution
Check the cluster configuration information and check whether the scale-in meets the following conditions:
- The cluster consists of rings of four or five hosts each, with primary, standby, and secondary DNs deployed on them. A cluster ring is the smallest unit for scaling in, which requires at least two rings. The system removes nodes from the last ring to the first when scaling in.
- The removed nodes cannot contain the GTM, CM Server, or CN component.
- The cluster status is Normal, and no other task information is displayed.
- The cluster tenant account cannot be in the read-only, frozen, or restricted state.
- The cluster is not in logical cluster mode.
- A yearly/monthly cluster to be scaled in cannot be in the grace period.
