How to export a volume over NFS outside of a project on 3Engines Cloud[🔗](#how-to-export-a-volume-over-nfs-outside-of-a-project-on-brand-name "Permalink to this headline")
=============================================================================================================================================================================

**Prerequisites**

Two Ubuntu servers in various projects (not in a private network) which all have a floating IP assigned.

```
Host: 64.225.128.1
Client: 64.225.128.2

```

On both servers we will create a directory /xdata, which will be shared.

**On the host**

```
eouser@host:~$ sudo apt-get update
eouser@host:~$ sudo apt-get install nfs-kernel-server
eouser@host:~$ sudo mkdir /xdata
eouser@host:~$ sudo chown nobody:nogroup /xdata
eouser@host:~$ sudo nano /etc/exports

```

Add the line:

```
/xdata 64.225.128.2(rw,sync,no_subtree_check)

```

Save the file.

Start the server:

```
eouser@host:~$ sudo systemctl restart nfs-kernel-server

```

For Ubuntu, start the server with this command:

```
eouser@host:~$ sudo service nfs-kernel-server start

```

Now go to <https://horizon.3Engines.com/project/security_groups/>

Create new security group.

Give it a name (eg. allow\_nfs) and save by clicking “Create security group” button.

Click “manage rules”.

Click “add rule”

Choose:

Rule: Custom TCP Rule

Direction: Ingress

Openport: Port

Port: 2049

Remote: CIDR

CIDR: 64.225.128.2

Click “Add”

Go to <https://horizon.3Engines.com/project/instances/>

From the drop-down menu on the right of the “Host” instance, choose “Edit Security Groups”.

Click on the “plus” sign on the “allow\_nfs” group.

This will move the group from “All Security Groups” to “Instance Security Groups”.

Click “Save”.

**On the Client**

```
eouser@client:~$ sudo apt-get update
eouser@client:~$ sudo apt-get install nfs-common
eouser@client:~$ sudo mkdir /xdata
eouser@client:~$ sudo mount 64.225.128.1:/xdata /xdata

```

You can check if the directory is mounted:

```
eouser@client:~$ df -h

```
