## POST /api/v2/vps/{id}/actions/resize-disk

**Resize VPS disk**

Resize an existing VPS disk. Get `diskId` and the per-disk `actions.canResize` gate from `GET /api/v2/vps/{id}/disks` or the storage endpoint. Set `incremental: true` to add `sizeGb` more GiB; omit it or set false to request the target size. For regular VPS services, non-root attachable disks consume Attachable Block Storage from `GET /api/v2/vps/{id}/storage-quota` `attachable.availableGb`; if there is not enough capacity, first increase `additionalStorageGb` through `GET /api/v2/vps/{id}/actions/upgrade` and `POST /api/v2/vps/{id}/actions/config`, then retry. Root/main disk expansion is different: when the disk gate says to use Billing/Add Resources, change the `storageGb` configurable option through the same config flow instead of calling this endpoint directly. After the virtual disk grows, the customer may still need to expand the partition/filesystem inside the VPS operating system.
