If you don't set up that child for sharing, the client will see the dataset folder, but not be able to access it. This is great from a security point-of-view, but I realize it can be a bit annoying. For example, if you have a dataset that is the parent of another, you would still have to set up sharing on that child if you wanted it to be shared, even if you have already set up sharing on the parent. Each dataset is treated like its own filesystem, with its own rules and settings, which means with regards to sharing over NFS, that you can share more securely as client's will not be able to reach out of the bounds of that dataset/filesystem that you decided to share.Īn important thing to bear in mind is that you will need to run the steps below for sharing on every pool/dataset that you wish to share, no matter the hierarchy. The great thing about ZFS is that it is very easy to split your "pool" into as many datasets as you like. It is important to use one or the other for sharing your ZFS datasets, but never both. This is because we will be using ZFS to manage the ZFS shares, and not /etc/exports. ![]() When it comes to sharing ZFS datasets over NFS, I suggest you use this tutorial as a replacement to the server-side tutorial. On my NFS server, which is running Ubuntu 18.04 LTS server, I first install OpenZFS.You might have seen my previous tutorials on setting up an NFS server and a client. If you already have a zpool up and running, skip this step. Lastly, the commands being run on the NFS server have the prompt, server $ and the commands to be run on the client side have the prompt client $ Creating OpenZFS pool and Dataset 1. I wouldn’t recommend running NFS over public internet without additional security measure. If you have an ‘open Wifi’ setup or if the security on your router’s endpoint is dubious, this would not guarantee any security. This would ensure that only devices which have connected to my LAN are accessing my files and the outside world can’t access it. The NFS server will be configured to allow only devices with only the aforementioned IP address to be have access to the NFS server. In plain English, this means that all the devices connected to my home network (WiFi and Ethernet, et al) will have IP addresses ranging from 192.168.0.2 through 192.168.0.254. The NFS is supposed to be available only on my LAN which has the subnet mask of 255.255.255.0 and 192.168.0.1 as its default gateway. My reason for using Ubuntu 18.04 is that it is quite popular and would considerably reduce the barrier of entry. You can use your favorite Linux distro or FreeBSD, or any other OS that supports OpenZFS. My NFS server is going to be based on Ubuntu 18.04 LTS. For now let’s focus on an Ubuntu server offering NFS storage and a Ubuntu client trying to connect to it. I will detail the creation of NFS mount point on a Windows 10 client in the Part 2 of this series. This way you can have the reliability and robustness of ZFS with the user friendliness of your favorite Desktop OS, since NFS is available across all platforms. ![]() ![]() This NFS device can then be mounted on your desktop workstation. Well in this blog post, I will discuss how you can create a Network File System, or NFS, running in a seperate server. Maybe, you are using Windows 10, which doesn’t support OpenZFS, yet. Maybe you also want it on your desktop, but you don’t want to reformat your existing disks and partitions. If you are familiar with OpenZFS, you know all about its feature rich interface, flexible architecture, reliable checksums and COW mechanisms.
