Amazon EFS must have an associated tag

Tags are key-value pairs that you attach to AWS resources to better organize them. They are particularly useful when you have many resources of the same type. By using tags, customers with multiple Amazon EFS can easily access and analyze a specific set by filtering on those that contain the same tag. Two of the key advantages of tagging your Amazon EFS are: Grouping and Filtering and Cost allocation.

Amazon Elastic File System (EFS)

Amazon Elastic File System (Amazon EFS) provides simple, scalable, elastic file storage for use with AWS Cloud services and on-premises resources. It is easy to use and offers a simple interface that allows you to create and configure file systems quickly and easily. Amazon EFS is built to elastically scale on demand without disrupting applications, growing and shrinking automatically as you add and remove files, so your applications have the storage they need, when they need it.
