Mounting EFS file systems
In the following section, you can learn how to mount your Amazon EFS file system on
a Linux
instance using the Amazon EFS mount helper. In addition, you can find how to use the
file fstab to automatically remount your file system after any
system restarts. To learn more about the Amazon EFS mount helper, see EFS Mount Helper.
Amazon EFS does not support mounting from Amazon EC2 Windows instances.
Before the Amazon EFS mount helper was available, we recommended mounting your Amazon EFS file systems using the standard Linux NFS client. For more information on those changes, see Mounting File Systems Without the EFS Mount Helper.
You can configure a new Amazon EC2 Linux instance to mount an Amazon EFS file system when it launches. However, before you mount a file system, you must create, configure, and launch your related AWS resources. For detailed instructions, see Getting Started with Amazon Elastic File System.

Installing the amazon-efs-utils package
To mount your Amazon EFS file system on your Amazon EC2 instance, we recommend that you use the mount helper in the amazon-efs-utils package. The amazon-efs-utils package is an open-source collection of Amazon EFS tools. For more information, see Installing the amazon-efs-utils Package on Amazon Linux.
