Mounting EFS file systems

To mount EFS file systems, we recommend that you use the EFS mount helper. The EFS mount helper helps you mount your EFS file systems on EC2 Linux and Mac instances running the supported distributions. The mount helper is part of the open-source collection of tools that is installed when you install the Amazon EFS client (amazon-efs-utils). For more information about the Amazon EFS client and the supported distributions, see Installing the Amazon EFS client.

Alternatively, you can manually mount EFS file systems using the standard Linux NFS client. Amazon EFS supports the Network File System versions 4.0 and 4.1 (NFSv4) protocols when mounting your file systems on Amazon EC2 instances.

Additionally, you can use the EFS mount helper or NFS to configure an EC2 instance to automatically mount an EFS file system when the instance starts.
