Amazon FSx for Lustre - AWS ParallelCluster

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, AWS ParallelCluster creates a managed FSx for Lustre file system from FsxLustreSettings when it creates the cluster. AWS 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 AWS ParallelCluster managed FSx for Lustre file system, you can use the FsxLustreSettings / DeletionPolicy to instruct AWS 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 AWS 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 AWS services, see AWS Backup in the AWS Backup Developer Guide.
