Checking the File System

Using the Dynamic Resource Allocation Feature

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.

Before you use a Dynamic Resource Allocation feature, Quantum strongly recommends running the cvfsck command on the file system you will be using. This step could take a considerable amount of time to complete, but your file system should be in good condition before you attempt to expand it or move stripe groups.

Caution: If you do not run the cvfsck command to check your file system before attempting file system expansion, irreparable file system damage could occur.

Adding a Stripe Group Without Moving

Use the following procedure to expand the file system by adding a stripe group, and not migrating.

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 movement 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.

5Stop the File System Manager (FSM).
