Mounting EFS file systems

In the following section, you can learn how to mount your Amazon EFS file system on an Amazon EC2 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. Using the EFS mount helper, you have the following options for mounting your Amazon EFS file system:

• Mounting on supported EC2 instances

• Mounting with IAM authorization

• Mounting with Amazon EFS access points

• Mounting with an on-premise Linux client

• Auto-mounting when an EC2 instance reboots

• Mounting a file system when a new EC2 instance launches

The EFS mount helper is part of the amazon-efs-utils package. The amazon-efs-utils package is an open-source collection of Amazon EFS tools. For more information, see Manually installing the Amazon EFS client.

Note

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, see Mounting file systems without the EFS mount helper.
