Mounting File Systems From Windows Instances

Users of Windows Server 2008 R2, 2012 R2, or 2016 can mount a file system to any available drive letter using the mount target IP address and the file system export path.

On the instance from which you want to mount the file system, you need to install the Windows NFS client.

Warning

Installing the Windows NFS client may require a restart of your system.

Access to NFS file systems requires UNIX-style user and group identities, which are not the same as Windows user and group identities. To enable users to access NFS shared resources, Windows client for NFS accesses file systems anonymously, using 'AnonymousGid' and 'AnonymousUid'. On brand new file systems, write permissions are only granted to the root user. The 'AnonymousGid' and 'AnonymousUid' identity values must be changed to allow write access.

Warning

Updating the 'AnonymousGid' and 'AnonymousUid' values require registry changes to your system.

After you have installed the NFS client and correctly mapped user identities, you can mount the file system using the command line or Map network drive dialog to any available drive letter. You can access your file system through the chosen drive letter to write files.

Prerequisites

  • The file system must be associated with a mount target. File systems are generally associated with a mount target when they're created. However, they can be associated to more than one mount target, or detached from all mount targets. See Managing File Systems for more information.
  • Correctly configured security list rules in the VCN subnet where the file system's associated mount target resides. See Security Lists for information about how security lists work in Oracle Cloud Infrastructure. Use the instructions in Configuring VCN Security List Rules for File Storage to set up security lists for your file systems.

Warning

When mounting file systems, don't use mount options such as nolock, rsize, or wsize. These options cause issues with performance and file locking.
