Updating the mount target configuration - Amazon Elastic File System

Updating the mount target configuration

After you create a mount target for your file system, you might want to update security groups that are in effect. You can't change the IP address of an existing mount target. To change an IP address, delete the mount target and create a new one with the new address. Deleting a mount target breaks any existing file system mounts.

Note

Before deleting a mount target, first unmount the file system.

Modifying a security group

Security groups define inbound and outbound access. When you change security groups associated with a mount target, make sure that you authorize necessary inbound and outbound access. Doing so enables your EC2 instance to communicate with the file system.

For more information about security groups, see Amazon EC2 Security Groups in the Amazon EC2 User Guide for Linux Instances.

To modify a mount target's security group using the AWS Management Console, see Managing mount targets using the Amazon EFS console.

To modify a mount target's security group using the AWS CLI, see Managing mount targets using the AWS CLI.
