Creating File Systems

You can create a shared file system in the cloud using the File Storage service. Network access to your file system is provided through a mount target. Exports control how NFS clients access file systems when they connect to a mount target. File systems must have at least one export in one mount target for any instance to mount and use the file system. Typically, you create your first mount target when you create your first file system.


Avoid entering confidential information when assigning descriptions, tags, or friendly names to your cloud resources through the Oracle Cloud Infrastructure Console, API, or CLI.

Required IAM Service Policy

To use Oracle Cloud Infrastructure, you must be given the required type of access in a policy  written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which compartment  you should work in.

For administrators: The policy in Let users create, manage, and delete file systems allows users to create file systems. Since mount targets are network endpoints, users must also have "use" permissions for VNICs, private IPs, private DNS zones, and subnets to create or delete a mount target. See the Policy Reference for more information.

If you're new to policies, see Getting Started with Policies and Common Policies.


Before you create a file system, you need:

  • At least one Virtual Cloud Network (VCN) in a compartment. For more information, see VCNs and Subnets.
  • Correctly configured security rules for the file system mount target. Security rules can be created in the security list for the mount target subnet, or in a Network Security Group (NSG) that you add the mount target to. See Security Rules for information about how security rules work in Oracle Cloud Infrastructure. Use the instructions in Configuring VCN Security Rules for File Storage to set up security rules correctly for your file systems
