NFS¶
Only operating systems from the Unix family - Linux, MacOS - will be accessing this NAS and the environment is relatively secure, so we can use NFS instead of Samba for better performance.
sudo apt install nfs-kernel-server
We link the various datasets through a folder so we don’t have to export the actual datasets. This is experimental.
mkdir /exports
ln -s /tank/pictures/ /exports/pictures
ln -s /tank/coldstore/ /exports/coldstore
ln -s /tank/media/ /exports/media
ln -s /tank/storage/ /exports/storage
ln -s /tank/texts/ /exports/texts
In /etc/exports, add the following lines:
Note
We leave the addresses as 192.168.0.0 instead of 192.168.13.0 as might be expected because we’ll be putting the high-speed SFP+ network on a different subnet at some point.
/exports *(ro,fsid=0,no_subtree_check)
/exports/pictures 192.168.0.0/255.255.0.0(rw,no_subtree_check)
/exports/coldstore 192.168.0.0/255.255.0.0(rw,no_subtree_check)
/exports/media 192.168.0.0/255.255.0.0(rw,no_subtree_check)
/exports/storage 192.168.0.0/255.255.0.0(rw,no_subtree_check)
/exports/texts 192.168.0.0/255.255.0.0(rw,no_subtree_check)
On the target machine, we need the setup in /etc/fstab:
home.local:/exports/coldstore /mnt/coldstore nfs noatime,noauto 0 0
home.local:/exports/storage /mnt/storage nfs noatime,auto 0 0
home.local:/exports/media /mnt/media nfs noatime,auto 0 0
home.local:/exports/pictures /mnt/pictures nfs noatime,auto 0 0
Then run sudo exportfs -a to make sure we know about this. Finally, just to be sure, try
sudo systemctl restart nfs-kernel-server
