This procedure creates new volumes on an existing NFS-enabled storage VM. You can accept system defaults when configuring volumes or specify custom configurations.

You can create FlexVol volumes, or for large file systems with high performance requirements, you can create FlexGroup volumes. See also Provision NAS storage for large file systems using FlexGroup volumes.

If you want details about the range of ONTAP NFS protocol capabilities, consult the NFS reference overview.

Steps

Add a new volume in an NFS-enabled storage VM.
1. Click Storage > Volumes and then click Add.
2. Enter a name, select the storage VM, and enter a size.
  
  Only storage VMs configured with the NFS protocol are listed. If only one storage VM configured with the SMB protocol is available, the Storage VM field is not shown.
  - If you click Save at this point, ONTAP System Manager uses system defaults to create and add a FlexVol volume.
    
    The default export policy grants full access to all users.
  - You can click More options to customize the configuration of the volume to enable services such as authorization, quality of service, and data protection. Refer to Customize the volume configuration, then return here to complete the following steps.
On a Linux client, do the following to verify access.
1. Create and mount the volume using the network interface of the storage VM.
2. On the newly mounted volume, create a test file, write text to it, and then delete the file.
After verifying access, you can restrict client access with the volume’s export policy and set any desired UNIX ownership and permissions on the mounted volume.

Customize the volume configuration

You can customize the volume configuration when you add volumes instead of accepting the system defaults.

Procedure

After clicking More options, select the functionality you need and enter the required values.

Cache for remote volume.
Performance service level (quality of service, QoS).

Beginning with ONTAP 9.8, you can specify a custom QoS policy or disable QoS, in addition to the default Value selection.
- To disable QoS, select Custom, Existing, then none.
- If you select Custom and specify an existing service level, a local tier is automatically chosen.
- Beginning with ONTAP 9.9.1, if you choose to create a custom performance service level, you can use ONTAP System Manager to manually select the local tier (Manual placement) on which you want to place the volume you are creating.
  
  This option is not available if you select the remote cache or FlexGroup volume options.
FlexGroup volumes (select Distribute volume data across the cluster).

This option is not available if you previously selected Manual placement under Performance Service Level. Otherwise, the volume you are adding becomes a FlexVol volume by default.
Access permissions for the protocols for which the volume is configured.
Data protection with SnapMirror (local or remote), then specify the protection policy and settings for the destination cluster from the pull-down lists.
Select Save to create the volume and add it to the cluster and storage VM.

After you save the volume, return to Step 2 in the workflow to complete provisioning for Linux servers using NFS.
