Chapter 6 Managing the File System

Understanding Dynamic Resource Allocation

5If the Stub File feature is enabled, indicate how StorNext determines the stub file size:

By Policy: Use the stub file size entered when the storage policy was created

User Set: Change the stub file size by entering the new size (in kilobytes) at this field

6Click Apply to modify attributes for the selected files.

7After the Status screen informs you that the operation was completed successfully, click OK.

Understanding Dynamic Resource Allocation

About File System Expansion

StorNext provides two Dynamic Resource Allocation tools that allow you to make changes to your file system: File System Expansion, and Stripe Group Movement.

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.

StorNext provides a File Expansion Wizard to simplify the process. Quantum recommends using this wizard for File System Expansion, but you can also use the command line interface. (For information about using the CLI, see Using the Dynamic Resource Allocation Feature.)
