3. Create a directory you want to share over the network:
3. Create and Attach an Empty Volume to the NFS Server:

3.1. [Create an Empty Volume](../../openstack/persistent-storage/create-an-empty-volume.md#using-horizon-dashboard).

3.2. [Attach the Volume to the NFS Server](../../openstack/persistent-storage/attach-the-volume-to-an-instance.md#using-horizon-dashboard).

Verify the 100GiB (**adjust based on your Storage requirements**) attached
volume is available on the NFS server VM:

```sh
lsblk
...
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
vda 253:0 0 20G 0 disk
├─vda1 253:1 0 19G 0 part /
├─vda14 253:14 0 4M 0 part
├─vda15 253:15 0 106M 0 part /boot/efi
└─vda16 259:0 0 913M 0 part /boot
vdb 253:16 0 100G 0 disk
```

3.3. [Format And Mount The Volume](../../openstack/persistent-storage/format-and-mount-the-volume.md#for-linux-based-virtual-machine).

Create a filesystem on the volume. In this example, we will create an `ext4`
filesystem:

```sh
sudo mkfs.ext4 /dev/vdb
```

3.4. Create a directory you want to share over the network:

```sh
sudo mkdir -p /mnt/nfs_share
```

4. Set the ownership and permissions to allow access (adjust based on requirements):
3.5. Mount it:

```sh
sudo mount /dev/vdb /mnt/nfs_share
```

Verify the mount path is set correctly:

```sh
df -H
...
Filesystem Size Used Avail Use% Mounted on
tmpfs 411M 1.1M 410M 1% /run
/dev/vda1 20G 2.0G 18G 10% /
tmpfs 2.1G 0 2.1G 0% /dev/shm
tmpfs 5.3M 0 5.3M 0% /run/lock
/dev/vda16 924M 65M 795M 8% /boot
/dev/vda15 110M 6.4M 104M 6% /boot/efi
tmpfs 411M 13k 411M 1% /run/user/1000
/dev/vdb 106G 29k 100G 0% /mnt/nfs_share
```

4. Set the ownership and permissions to allow access (**adjust based on requirements**):

Since we want all the client machines to access the shared directory, remove
any restrictions in the directory permissions.
