Adding an NFS file system

Before mounting the NFS clients to the exports exposed by a NAS Bridge node, you must add one or more NFS file systems.

Before you begin

You should be familiar with the prerequisites and limitations when adding file systems.

In addition, the following administrative entities must be defined to the NAS Bridge node:

StorageGRID Webscale API Gateway Node (defined as part of initial configuration)
Cache device that is available to the file system

About this task

When adding an NFS file system, you must type or select all of the parameter values displayed on the page. You can also include a permission for the file system. Regarding permissions, you should be aware of the following:

An NFS file system without permissions is read-only.
Adding a permission is required for write access.
You can add a permission when the file system is being defined or after it is defined.

Steps

Click Configuration at the top of the web page.
Click NFS Filesystems.
Click Add.
Type or select all of the configuration values as appropriate for your deployment plan and storage environment:
- Storage Grid – Select the IP address of the StorageGRID Webscale API Gateway Node.
- Bucket – If the named bucket does not exist in your StorageGRID Webscale system, NAS Bridge creates it.
- Cache device – Select the cache device you want to use for this file system.
- Export – The export name must begin with a slash. The export is exposed under the /mnt directory.
Click Add Permission, and type or select the permission values to allow write access to the NFS export:
1. Type the IP address or domain name of the clients.
  A wild card name is supported.
2. Click Readwrite.
3. Select the Squash value and anonymous IDs as needed.
4. Click Add.
Click Save to create the file system.
When the operation completes, the new file system is displayed with a unique ID and a status of READY.
When you are done making changes, export the configuration file.
1. Click Maintenance > Configuration Exports .
2. Click Generate Export.
3. Click the download icon to download the file to your local workstation.
4. Save the configuration file to a safe location.
  You will need this file to recover the NAS Bridge configuration in case of a failure.
After adding the NFS client in NAS Bridge, you can mount that client to the export exposed at a NAS Bridge node.
When mounting an NFS client, NetApp recommends that you use the rsize and wsize parameters to specify the block sizes for read and write operations. Otherwise, these operations might be slow. For example:
```
sudo mount {IP or Hostname}:/mnt/{export} {local folder} -o rsize=1048576,wsize=1048576
```
