About File System Expansion

StorNext’s File System Expansion feature enables you to dynamically add LUNs to a selected file system without interrupting that file system’s operation.

The only disruption that occurs during File System Expansion is a short pause of new metadata requests as StorNext updates its internal system and clients to be aware of the new overall capacity and physical disk resources that are used.

File System Expansion is often done in conjunction with the Stripe Group Movement feature. That is, you might want to add new stripe groups knowing you’ll want to use those stripe groups for Stripe Group Movement.
