Description

The aws_fsx_lustre_file_system resource currently supports the following values for deployment_type:

• SCRATCH_1
• SCRATCH_2
• PERSISTENT_1

As of approximately November 2021, AWS introduced the PERSISTENT_2 deployment type. This introduces a number of new features in FSx for Lustre, including the ability to create many data repository associations for a given file system. Unlike earlier PERSISTENT_1 data repositories, these associations can be configured to export data back to the source S3 bucket.¹

The current resource has import_path and export_path attributes. These would not be applicable to a PERSISTENT_2 deployment. For PERSISTENT_2 file system, its repository associations would need to be configured after the file system is created.

New or Affected Resource(s)

• aws_fsx_lustre_file_system
• aws_fsx_lustre_data_repository_association (new)

Potential Terraform Configuration

resource "aws_fsx_lustre_file_system" "example" {
  storage_capacity = 1200
  subnet_ids       = [aws_subnet.example.id]
  deployment_type  = "PERSISTENT_2"
}

resource "aws_fsx_lustre_data_repository_association" "example" {
  file_system_id       = aws_fsx_lustre_file_system.example.id
  file_system_path     = "/example"
  data_repository_path = "s3://${aws_s3_bucket.example.bucket}"
  
  s3 {
    auto_import_policy = "NEW_CHANGED_DELETED"
    auto_export_policy = "NEW_CHANGED_DELETED"
  }  
}
