Mounting an Amazon EFS File System on an EC2 Instance

To access a file system on Amazon Elastic File System (EFS) from an Amazon EC2 instance, you need to mount the file system on the instance using the standard Linux mount command and the file system's DNS name [1].

Here are the steps to mount an Amazon EFS file system on an EC2 instance:

  1. Install the NFS client package: Ensure that the NFS client package is installed on the EC2 instance. Most Linux distributions come with the NFS client pre-installed, but if it's not available, you can install it using the package manager for your distribution.

  2. Create a mount target: Before you can mount an EFS file system, you need to create a mount target in the same Amazon Virtual Private Cloud (VPC) as your EC2 instance. This allows the instance to access the file system securely.

  3. Retrieve the file system's DNS name: Get the DNS name of the EFS file system you want to mount. You can find this information in the Amazon EFS console or by using the AWS Command Line Interface (CLI).

  4. Mount the file system: Use the mount command to mount the EFS file system on the EC2 instance. The command should include the file system's DNS name and the mount point directory on the instance.

For example, if the file system's DNS name is fs-12345678.efs.us-west-2.amazonaws.com and you want to mount it at the directory /mnt/efs, you can use the following command:

sudo mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2 fs-12345678.efs.us-west-2.amazonaws.com:/ /mnt/efs

This command mounts the file system using NFSv4.1 and sets some options for performance and reliability.

  1. Verify the mount: After mounting the file system, you can verify that it is accessible from the EC2 instance by listing the files and directories in the mount point directory.

ls /mnt/efs

If the command lists the files and directories in the EFS file system, it means the mount was successful.

That's it! You have now mounted an Amazon EFS file system on an EC2 instance. You can work with the files and directories in the file system just like you would with a local file system [1].
