Scaling up Cloud Disks

Last updated: 2023-12-27 11:06:40

Overview
If the data storage space of a node becomes insufficient as your business grows, you need to expand the space. This document describes how to scale up cloud disks in the EMR console.
Caution
You can scale up only cloud data disks but not system disks and local disks.
You cannot batch scale up cloud data disks on multiple nodes.
For your data security, we recommend you create snapshots of your cloud disks before scale-up.
To prevent data loss, a disk can be scaled up only but not scaled down.
Scaling up Cloud Disks
Directions
1. Log in to the EMR console and click the ID/Name of a target cluster in the cluster list to go to the cluster details page.
2. Click the Resource Management tab and then click Scale up cloud data disk in the Operation column of the target node to enter the settings page.
﻿
3. If multiple cloud data disks are mounted to the current node, you can batch scale them up to the same capacity.
﻿
4. Disks will be initialized automatically after scale-up, and you don't need to manually update the disk information.
