In this segment we are going to talk about NFS. How to deploy and configure it.

We are going to use apt to install NFS server.

root@node5:/home/ubuntu# apt install nfs-common

Need to get 381 kB of archives.
After this operation, 1,447 kB of additional disk space will be used.
Do you want to continue? [Y/n]

In this example I have a directory (/mnt/lviso) which I want to share out to a entire network.
Edit the file /etc/exports The exports directory provides the instructions which describe which parts of the system we are gong to export and to which network locations.

/mnt/lviso 192.168.160.0/24(rw,sync,no_subtree_check)

The following command instructs the NFS subsystem to rescan the “exports” and update accordingly.

$ sudo exportfs -a

Now it’s time to restart the NFS service. If this wasn’t already started.

$ sudo systemctl restart nfs-kernel-server

Manually mounting a NFS filesystem

$ sudo mount -t nfs 172.16.104.251:/lvnfs /mnt
