On nas:

apt update
apt install nfs-kernel-server
systemctl enable nfs-server
systemctl start nfs-server

Export datasets via nfs in /etc/exports:

/dpool/media    192.168.1.0/24(rw,async,no_subtree_check,no_root_squash)

# The config on lab needed an FSID
/mnt/storage        192.168.1.0/24(rw,sync,crossmnt,fsid=0)

Apply config:

exportfs -ra
systemctl reload nfs-server

Verify shares:

exportfs -v
showmount -e localhost

On client node:

apt install nfs-common
mkdir -p /mnt/nas/media
mount -t nfs <NAS_IP>:/dpool/media  /mnt/nas/media

Mounting manually worked fine for me but when I tried mounting from etc/fstab, I was getting mount errors saying the folder/file didn’t exist. I’ll sort out the errors later.

<NAS_IP>:/dpool/media /mnt/nas/media nfs4 rw,_netdev,noatime,hard,intr 0 0
