Expansion and Movement Steps

Chapter 6 Managing the File System

Understanding Dynamic Resource Allocation

Note: After expansion you must perform a metadata dump. The File Expansion Wizard includes an option that will do this for you automatically, but the process can take longer than if you do the metadump manually.

Stripe Group Movement accomplishes two purposes: moving data files between stripe groups, and freeing stripe groups so they can be removed from an existing StorNext file system.

Before movement, the stripe group should be in read-only mode (write disabled).

During Stripe Group Movement, you indicate one or more source stripe groups from which to move data. StorNext then automatically moves all data of the same type (either data or metadata,) from the source stripe groups to the remaining stripe groups in the file system. All other stripe groups are targets, allowing an even distribution of data across remaining disk resources. During movement the file system is left online and read/write operations occur normally.

After all data has been removed from the source stripe group, you must mark the stripe group as “down,” which prevents new data from being written to the source stripe group. If desired, a system administrator can then remove the source stripe group from the StorNext configuration, or use the disks in other file systems.

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

Here are the steps required for expanding a file system and moving stripe groups:

1Check the file system before you begin. (See Checking the File System on page 143.)

2Expand the file system. (See Performing File System Expansion on page 145.)

3Move data stripe groups or metadata/journal stripe groups. (See Performing Stripe Group Movement on page 152.)
