Chapter 6 Managing the File System

Performing File System Expansion

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.

Note: During File System Expansion the file system is shut down. After expansion you must perform a new metadata dump runs after the file system is updated. For managed file systems, the File System Expansion wizard includes an option for you to run the metadump automatically, or you can do it separately from the wizard.

As a final part of the File System Expansion process, StorNext restarts the file system. This restart typically takes less than two minutes and is often completed in seconds, but during the restart all new read/write requests are paused while operations in progress continue normally.

Caution: When you add a new disk or stripe group to your SAN, often an OS-dependent operation must be run to make the added device recognizable by a host. Some of these utilities can disrupt access to existing disks, causing access hangs or failures. To avoid this, stop all file system operations on the affected host before rescanning for the new device.

Follow these steps when you are ready to use the File System Expansion Wizard:

1From the SNFS home page, choose Expand File System from the Admin menu. The File System Expansion - Introduction screen appears, showing a list of file systems available for expansion.
