Getting Started with Amazon FSx for Lustre

Verify that your environment meets the system requirements, complete the file server service catalog, add a subclient, and then perform a test backup and restore.

Procedure

1. Create a backup plan from Command Center.

2. Verify that your environment meets the requirements.

   • Pre-deploy the access nodes and the storage in the same region as the Amazon FSx for Lustre file share.

   • Access nodes for Amazon FSx for Lustre must be running Red Hat-based Linux Distributions supported by Amazon.

     • Lustre file system and client kernel compatibility

   • Lustre is supported only on x64 processors.

   • The fileset feature is not supported.

   • There is no access to MDS/MDT servers for optimized scanning.

     • Each 100 million files require approximately 3 hours and 10 minutes of scan time, and every 100 to 150 TB of application data needs one large access node.

     • Commvault recommends having a minimum of two access nodes for improved parallelization and redundancy.

     • Load balancing across nodes gives better overall performance.

       • For example, if backing up 400 TB data, Commvault recommends using four medium-sized access nodes rather than two large-sized access nodes.

     Example Scan Time

     Items scanned	Time taken to scan	Content
     100 million in 1 subclient	3 hours 10 minutes	Entire volume: /lustrefs

     Note

     For faster scanning times with a very large number of files, especially where there is no access to the MDS for fast incremental scanning, you can create multiple subclients and split the data across them to run multiple jobs in parallel.

3. Follow these guides to mount the Lustre file system to the access nodes.

   • Installing the Lustre client

   • Mounting from an Amazon Elastic Compute Cloud instance

4. Configure the LustreUseRecursiveScan setting on the access nodes.

   Configure the LustreUseRecursiveScan additional setting.

   1. From the Command Center navigation pane, go to Manage > Infrastructure > Server groups.

   2. Click Add server group.

   3. Enter the Server group Name.

   4. Click Add Server.

   5. Find and select the access nodes, and then click Save.

   6. On the Configuration tab, on the Settings tile, click Add.

   7. Add the LustreUseRecursiveScan setting.

5. Add Amazon FSx for Lustre file storage.

6. Perform a backup.

7. Perform a restore.
