Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Amazon FSx for Lustre

To use an existing external FSx for Lustre file system for long-term permanent storage outside of the cluster life cycle, specify FsxLustreSettings / FileSystemId.

If you don't specify FsxLustreSettings / FileSystemId, by default, Amazon ParallelCluster creates a managed FSx for Lustre file system from FsxLustreSettings when it creates the cluster. Amazon ParallelCluster also deletes the file system and data when the cluster is deleted or when the file system is removed from the cluster configuration.

For an Amazon ParallelCluster managed FSx for Lustre file system, you can use the FsxLustreSettings / DeletionPolicy to instruct Amazon ParallelCluster to Delete or Retain the file system when either the cluster is deleted or when the file system is removed from the cluster configuration. By default, DeletionPolicy is set to Delete.

Warning

For Amazon ParallelCluster managed shared storage, DeletionPolicy is set to Delete by default.

This means that, if one of the following is true, a managed file system and its data are deleted:

  • You delete the cluster.

  • You change the managed shared storage configuration SharedStorage / Name.

  • You remove the managed shared storage from the configuration.

We recommend that you back up your shared storage regularly to avoid the loss of data. You can define backups in your cluster with SharedStorage / FsxLustreSettings / AutomaticBackupRetentionDays and DailyAutomaticBackupStartTime. To learn how to manage data backups across Amazon Web Services, see Amazon Backup in the Amazon Backup Developer Guide.
