Expanding the Disk Capacity of an HBase Cluster

The vertical capacity expansion is performed by expanding disk capacity. Data is usually stored on the compute nodes, and disk expansion is required when the disk capacity of the compute nodes is insufficient.

  • During disk capacity expansion, cluster services may jitter.
  • You can perform disk capacity expansion on a cluster when the cluster is in the In service state and no task is being performed (such as node scale-out and parameter modification).
  • When the disk usage of all core nodes reaches 90%, the cluster is abnormal and read and write operations are unavailable.

Procedure

  1. Log in to the CloudTable console.
  2. Click Cluster Management.
  3. Select the cluster to be expanded and choose Operation > More > Disk Expansion.

    You can also click Disk Expansion on the cluster details page to go to the page for expanding disk capacity.

  4. Click + to increase the disk capacity, confirm the fee and resource quota, and click OK.

Disk Expansion Status

Table 1 Disk expansion status description

Status

Description

Disk expanding

Indicates that a cluster is being scaled out.

In service

This status is shown in Cluster Status, indicating that the scale-out is complete and the cluster can provide services.

Scale-out failed

This status is shown in Task Status, indicating that the cluster fails to be scaled out.
