Mounting on Amazon EC2 Linux instances using the EFS mount helper

This procedure requires the following:

• You have installed the amazon-efs-utils package on the EC2 instance. For more information, see Manually installing the Amazon EFS client.

• You have created mount targets for the file system. For more information, see Managing mount targets.

To mount your Amazon EFS file system using the mount helper on EC2 Linux instances

1. Open a terminal window on your EC2 instance through Secure Shell (SSH), and log in with the appropriate user name. For more information, see Connect to your EC2 instance in the Amazon EC2 User Guide.

2. Create a directory efs that you will use as the file system mount point using the following command:

   sudo mkdir efs

3. Run one of the following commands to mount your file system.

   Note

   If the EC2 instance and the file system you are mounting are located in different AWS Regions, see Mounting EFS file systems from a different AWS Region to edit the region property in the efs-utils.conf file.

   • To mount using the file system id:

     sudo mount -t efs file-system-id efs-mount-point/

     Use the ID of the file system you are mounting in place file-system-id and efs in place of efs-mount-point.

     sudo mount -t efs fs-abcd123456789ef0 efs/

     Alternatively, if you want to use encryption of data in transit, you can mount your file system with the following command.

     sudo mount -t efs -o tls fs-abcd123456789ef0:/ efs/

   • To mount using the file system DNS name:

     sudo mount -t efs -o tls file-system-dns-name efs-mount-point/

     sudo mount -t efs -o tls fs-abcd123456789ef0.efs.us-east-2.amazonaws.com efs/

   • To mount using the mount target IP address:

     sudo mount -t efs -o tls,mounttargetip=mount-target-ip file-system-id efs-mount-point/

     sudo mount -t efs -o tls,mounttargetip=192.0.2.0 fs-abcd123456789ef0 efs/

   You can view and copy the exact commands to mount your file system in the Attach dialog box.

   1. In the Amazon EFS console, choose the file system that you want to mount to display its details page.

   2. To display the mount commands to use for this file system, choose Attach in the upper right.

      The Attach screen displays the exact commands to use for mounting the file system in the following ways:

      • (Mount via DNS) Using the file system's DNS name with the EFS mount helper or an NFS client.

      • (Mount via IP) Using the mount target IP address in the selected Availability Zone with an NFS client.
