Expanding the System Disk Capacity of a Lite Server Supernode

Scenario

When you use a supernode, the OS fails to be switched due to insufficient system disk space. Additionally, during routine service runtime, data is continuously increasing. As a result, the remaining space of the system disk decreases and finally reaches the upper limit, affecting service running.

To address these problems and ensure service continuity and stability, Lite Server allows you to expand the system disk capacity on the node details page. You can easily switch to the EVS page to expand the capacity as required, preventing operation failures or service interruption caused by insufficient space.

Constraints

Constraints on system disk scaling:

You need to expand the system disk space on the EVS page, which depends on the EVS capacity expansion feature.
System disk capacity cannot be reduced.

Billing

After the disk capacity expansion, the billing information will be displayed in the billing order generated during supernode creation. No new billing order is generated.

Expanding the System Disk Capacity of a Supernode

Log in to the ModelArts console.
In the navigation pane on the left, choose Lite Servers under Resource Management.
Figure 1 Resource list
In the Supernodes tab, click the target supernode to access its subnode details page.
On the subnode details page, locate the system disk to be expanded and click Expand on the right. Click Expand as prompted.
On the displayed EVS console, expand the disk capacity by referring to Expand Disk Capacity.
After the system disk capacity is expanded, manually synchronize the information on the ModelArts Lite Server page by referring to Synchronizing the Lite Server Status.
