17  Storage

We will use Network File System (NFS) storage to share data between servers.

17.1 Configure NFS server at 194.95.75.12

sudo apt update

sudo apt install -y nfs-server

Add

/ssd *(rw,sync,no_root_squash,no_subtree_check)

to /etc/exports.

Note

The format of /etc/exports is

<export> <host1>(<options>) <hostN>(<options>)...

sudo systemctl enable --now nfs-server

sudo exportfs -ar

17.2 Test NFS server

From 194.95.75.12, run

showmount -e 194.95.75.12

Export list for 194.95.75.12:
/ssd 192.168.12.8

Try to mount the NFS directory:

sudo mkdir /var/orc2_data/ssd

sudo mount -t nfs 192.168.12.8:/ssd /var/orc2_data/ssd

If successful, unmount the NFS directory:

sudo umount /var/orc2_data/ssd
