Create ext4 lvm partition with required space to be shared with clients. Mount created lvm partition on /export via UUID using /etc/fstab

Create home folder under /export
```
mkdir -p /export/home
```
Install NFS packages
```
apt install -y nfs-kernel-server
```
Enter the mount point in /etc/exports file and insert
```
/export <private-subnet>(rw,sync,no_subtree_check)
```
For example
/export 172.16.1.0/24(rw,sync,no_subtree_check)
Note that we are exporting entire /export from master and not just /export/home. Later we can create /export/apps for apps and other sub-folders for other purposes.

In case of infiniband use <infiniband-subnet> to export NFS instead of <private-subnet>
Export the new path
```
exportfs -a
```
Restart NFS server
```
systemctl restart nfs-kernel-server
```
