Mounting EFS file systems - Amazon Elastic File System

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.

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 on those changes, see Mounting File Systems Without the EFS Mount Helper.

Note

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.

Troubleshooting AMI and kernel versions

To troubleshoot issues related to certain Amazon Machine Image (AMI) or kernel versions when using Amazon EFS from an Amazon EC2 instance, see Troubleshooting AMI and Kernel Issues.

Note

Amazon EFS does not support mounting from Amazon EC2 Windows instances.

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.
