Adding and Moving a Data Stripe Group

Using the Dynamic Resource Allocation Feature

6Run the cvupdatefs command.

7Restart the FSM.

New functionality has been added to the snfsdefrag utility to support operations on multiple stripe groups.

Note: During Stripe Group Movement, affinities are preserved when files are moved from one stripe group to another. When you create a new stripe group to use with the Stripe Group Movement feature, the new stripe group must include sufficient space for its affinities. (You must add any affinities from the source stripe group to the new stripe group.)

Use the following procedure to add new stripe groups, and then move data off of the old stripe group.

1Label disks for the new stripe groups you want to add to the file system.

2If your StorNext configuration includes a failover environment, you must first shut down any standby FSMs that would start when you shut down the primary FSM. The move procedure will not complete successfully unless all FSMs are shut down.

Caution: If you do not shut down standby FSMs, file system corruption or data loss could occur.

3(Optional) Run the cvfsck command on the file system. See Checking the File System.

4Add the new stripe groups to the file system configuration and mark the old stripe groups as read-only. (Make sure the old stripe group is write disabled.)

5Stop the File System Manager (FSM) for the desired file system.

6Run cvupdatefs.

7Restart the FSM.
