# Mount NAS

Available in Classic

You can add a large-scale NAS storage to Cloud Hadoop cluster nodes. For more information about NAS, see the [NAS user guide](/docs/en/ko/nas-start-classic).

To mount NAS on the cluster server:

- [1. Create NAS volume](/docs/en/hadoop-chadoop-3-11#1-nas-%EB%B3%BC%EB%A5%A8-%EC%83%9D%EC%84%B1)
- [2. Register NAS Volume ACL](/docs/en/hadoop-chadoop-3-11#2-nas-%EB%B3%BC%EB%A5%A8-acl-%EB%93%B1%EB%A1%9D)
- [3. Mount NAS](/docs/en/hadoop-chadoop-3-11#3-nas-%EB%A7%88%EC%9A%B4%ED%8A%B8)

## 1. Create NAS volume

To create a NAS volume:

1. In the Classic environment on the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Storage** > **NAS** > **NAS Volume**.
2. Click the **[Create NAS volume]**.
3. Configure the NAS volume settings and create the NAS volume.
  - For more information on creating NAS volumes, see the [Create NAS volume (Classic)](/docs/en/ko/nas-use-nasvolume-classic) guide.
  - You can set ACL (Network Access Control) during the NFS access control configuration step when creating a NAS Volume.
4. In the settings popup, select a cluster server and use the < > buttons to move it. To add a server from another NAVER Cloud Platform account to a NAS volume, enter a private IP address in the **Custom Server IP** field and click **[Next]**.

## 2. Register NAS Volume ACL

Before mounting a NAS Volume, you must first add ACL settings for the relevant cluster. ACL can be set when creating a NAS Volume or through the **NFS access control** menu in the console after creating the NAS.

- When creating a NAS volume  

select a cluster server in the NFS access control settings and move it using the < > buttons, or enter a private IP address to complete the ACL (network access control) configuration. See [1. Create NAS volume](/docs/en/hadoop-chadoop-3-11#1-nas-%EB%B3%BC%EB%A5%A8-%EC%83%9D%EC%84%B1).

For more information on creating NAS volumes, see the [Create NAS volume (Classic)](/docs/en/ko/nas-use-nasvolume-classic) guide.

- If you already have a NAS Volume  

To set up ACL if the NAS Volume has already been created:

1. In the Classic environment on the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Storage** > **NAS** > **NAS Volume**.
2. From the NAS Volume list, select the NAS Volume for which you want to set ACL, then click **[Volume settings]**.
3. Click **NFS access control**.
4. In the settings popup, select the cluster server, move it with the < > buttons, and then click **[OK]**.
  - To add a server from another NAVER Cloud Platform account to a NAS volume, enter a private IP address in the **Custom Server IP** field at the bottom and click **[OK]**.

## 3. Mount NAS

This guide applies to the basic environment of Cloud Hadoop. (CentOS 6.x or later) For more information about NAS, see the [NAS user guide](/docs/en/ko/nas-start-classic).

1. After launching PuTTY, use SSH to access the cluster server where you want to mount the NAS. (See the [Connect cluster nodes via SSH](/docs/en/ko/hadoop-chadoop-3-2) guide.)
2. Use the `sudo su -` command to convert to the root account.

```
$ sudo su -
```
3. Refer to the following example to install NFS-related packages, run the RPC daemon, and create a mount point.

```
$ yum -y install nfs-utils
$ systemctl start rpcbind.service
$ mkdir /mnt/nfs_dir
```
  - `yum -y install nfs-utils`: Installs NFS-related packages (basic).
  - `systemctl start rpcbind.service`: Runs the RPC daemon.
  - `mkdir /mnt/nfs_dir`: Creates a mount point (directory) called `/mnt/nfs_dir` using the mkdir command.
4. Mount using the volume name received from the NAS console and the mount point created.

```
$ mount -t nfs {Mount info} {Mount point}
$ mount -t nfs 10.250.53.85:/n2536315_test /mnt/nfs_dir
```
5. Use the `df` command to check that the NAS has been mounted correctly.

```
$ df
```

              Note

              

To automatically mount the NAS when the server boots, add the volume information to `/etc/fstab`.
