Performing File System Expansion
In practical terms, expanding an existing file system means allocating
additional storage to that file system. You add additional storage by
creating a new stripe group in the file system configuration file, and
assigning new disks to the stripe group.
Here is an overview of the steps required to enable File System
Expansion:
1. Define new disk LUNs and make them available across the fibre
channel SAN to the metadata controller and StorNext clients.
2. Use the StorNext GUI to create a new stripe group from the LUNs.
3. Add the new stripe group to an existing file system.
After you perform these steps, StorNext automatically updates the
available file system capacity and presents the expanded file system to
the StorNext clients.
