Currently, disk capacities can only be expanded, but cannot be reduced.
Expanding an Available disk means that the to-be-expanded disk has not been attached to a server.
Shared EVS disks cannot be expanded when they are in the In-use state. Therefore, you need to detach the disk from all its servers before expanding a shared disk. Once the disk status to change to Available, you can perform the operations provided in this topic to expand the disk.
The disk list page is displayed.
When the disk status changes to Available, the disk is successfully detached.
The expansion page is displayed.
After the specifications are submitted, the disk list page is displayed.
When the disk status changes from Expanding to Available, the additional capacity has been added to the disk and the expansion succeeded.
If the expansion fails, customer service personnel will contact you and help you handle this error. Do not perform any operations on the disk before the customer service personnel contact you. If you require that the error be handled as soon as possible, contact our customer service personnel. The disk will no longer be charged once its status changes to Expansion failed.
The operation method varies depending on the server OS.
