Select additional disk for application #7739

Some NS8 applications may require large amounts of storage for their data. To prevent filling the primary node’s storage—which is reserved for container data and benefits from fast random access performance—the workflow allows selecting an additional disk to store application data.

Scenario

The user installs, restores, moves or clones an application and wants to use an additional disk for its data storage.

Solution

• During the node selection step, nodes with additional disks are clearly marked.

• The user selects the NS8 node where the application will be installed, restored, moved or cloned.

• In the next step, the user chooses where to store the application data: either in Default storage¹ or on an available additional disk. Each disk displays its total size and available free space.

• If the selected node has no additional disks, the workflow ends after node selection.

• Once the workflow is completed, the chosen storage location cannot be changed.

Non-goals

The available disk space check, extremely useful in restore, move and clone scenarios, is a future goal.
