An NFS file system. To allow access to a file system, add it to an export set and associate the export set with a mount target. The same file system can be in multiple export sets and associated with multiple mount targets.
To use any of the API operations, you must be authorized in an IAM policy. If you’re not authorized, talk to an administrator. If you’re an administrator who needs to write policies to give users access, see Getting Started with Policies.
