Expanding the Capacity of an EVS Disk

When the storage space of an EVS disk is insufficient, you can handle the insufficiency in either of the following ways:
  • Create an EVS disk and attach it to an ECS.
  • Expand the capacity of an existing EVS disk. The capacities of both system disks and data disks can be expanded.
    You can expand the disk capacities when the EVS disks are in the In-use or  Available state.
    • Expanding an In-use EVS disk means that the to-be-expanded EVS disk has been attached to an ECS. Only certain ECS OSs support the expansion of In-use EVS disks. For details, see section "Expanding an In-use EVS Disk" in Elastic Volume Service User Guide.
    • Expanding an Available EVS disk means that the to-be-expanded EVS disk has not been attached to an ECS. For details, see section "Expanding an Available EVS Disk" in Elastic Volume Service User Guide.
