ZFS is extremely powerful, and since it’s natively supported in TrueNAS, setting up snapshots and scrub tasks is nothing more than a few clicks. Where these operating systems start to differ is with data protection. This is the most important function of any NAS, and while the setup process is different depending on the operating system that you’ll be using, the functionality and end-user experience will be similar. With both operating systems, you’ll create shared folders that can be accessed through your network (SMB, NFS, etc). OpenMediaVault and TrueNAS are very similar when it comes to adding and removing data from your NAS. There are so many benefits of ZFS that I can’t list them all here, but I’d definitely suggest you check out this article to learn about some of them. RAIDZ1 allows one hard drive to fail without data loss (similar to RAID 5), and RAIDZ2 allows two hard drives to fail without data loss (similar to RAID 6). When you set up a storage pool in TrueNAS, most people will use RAIDZ1 or RAIDZ2. You can install OMV-Extras to get it working, but generally, I’d just rather use TrueNAS if ZFS is a requirement. I also shy away from using ZFS on OpenMediaVault, but that’s not to say that it doesn’t work. If you’re using BTRFS, you want to ensure that you configure data scrubbing, so OpenMediaVault’s ease of use falls a little short in this category. The biggest downside of OpenMediaVault (at least at this point in time) is that many of the benefits of BTRFS (data scrubbing, for example) must be completed through the CLI. OpenMediaVault File SystemĪfter you create your RAID array in OpenMediaVault, you will be able to create a file system. There are also somewhat strict hardware requirements which we’ll take a look at below. As an example, if you’d like to install a NAS operating system on a Raspberry Pi, TrueNAS isn’t an option. However, you must keep in mind that the device you’re using must support TrueNAS. If you do and you want native ZFS support (meaning that you don’t need additional plugins), you won’t be able to use OpenMediaVault and will be forced to use TrueNAS. OpenMediaVault ZFS PluginĪll of the filesystems that can be set up on OpenMediaVault are extremely different and the one question you’ll need to answer is if you want to use ZFS. OpenMediaVault technically supports ZFS, but you must install a plugin, where TrueNAS supports ZFS natively. OpenMediaVault gives users the ability to set up a volume as various different types of filesystems, with the main being Ext4, XFS, and BTRFS. The first, and the biggest difference between OpenMediaVault and TrueNAS is the file systems that they use. Regardless of the version that you use (TrueNAS Core or Scale), TrueNAS is free and open-source. They both have similarities and differences, so I urge you to read about their differences if you decide to use TrueNAS as you’ll be able to make an informed decision on which version is best for you. TrueNAS Scale was created in 2022 and is built on Debian Linux. TrueNAS Core was created in 2005 (formerly known as FreeNAS) and is built on FreeBSD. TrueNAS is different in the fact that there are two different versions: TrueNAS Core and TrueNAS Scale. TrueNAS is an operating system developed on the OpenZFS file system. Overall, that hits the majority of systems out there and makes OpenMediaVault a consideration for most people as their hardware will almost certainly work with the OS. To expand on OpenMediaVault’s compatibility, it can be installed on bare metal, as a virtual machine, or even on a Raspberry Pi (which means that you can technically turn a Raspberry Pi into a NAS). Due to how easy it is to use OpenMediaVault, it’s a great NAS operating system to learn on. OpenMediaVault has all of the features you’d expect from a NAS operating system, but my favorite feature of OpenMediaVault is how user-friendly it is and its compatibility with different types of hardware. OpenMediaVault is an open-source network-attached storage (NAS) operating system based on Debian Linux.
