Disk-intensive ECSs can use both local disks and EVS disks to store data. Local disks are generally used to store service data and feature higher throughput than EVS disks.
Disk-intensive ECSs do not support modifying specifications. Therefore, when the idle capacity of the local disks of such an ECS is insufficient, you must create a new disk-intensive ECS with higher specifications for capacity expansion. In such a case, the data stored in the original ECS can be migrated to the new ECS through an EVS disk.
If the ECS is in the Running state, choose More > Stop to stop it.
The idle local disk capacity of the new ECS must meet service requirements.
On the Elastic Cloud Server page, click the name of the ECS described in step 5. The page providing details about the ECS is displayed.
In the displayed dialog box, select the EVS disk detached in step 4 and the device name.
