Can Unraid use SMR hard drives? The SMR vs CMR debate.
Yours is likely different. More on that below. Before you get started, it might be good to familiarize yourself with the unRAID manual. Before you shutdown Windows Backup everything. This is a good time to remind yourself that RAID is not a backup strategy.
You should already have a Backup Strategy. Getting a good backup is really more important than this. I like Crashplan for cloud and on-site location backups. If you have Windows 10, this is really really important. The easiest way to keep the key is to create an Admin user that logs in using a Microsoft Account credentials. In my case, I had a 4TB drive that I could copy my 1. You can check what type of disk it is by looking in the Windows Disk Management console.
Do Not Remove the Mirror. Breaking it keeps the data in place on both disks. Removing it deletes the data from one of the disks. I used a program called TestDisk. For detailed instructions, this walk through here was really useful. Run a comparison. I used Beyond Compare utilizing the binary comparison option in the settings. Beyond Compare Settings That is.
You can now power down your Windows machine for the last time. Now would be a good time to do any drive swapping you intend to do. In my case, I actually pulled out one of the 1. Whatever disks you assign to your array will be deleted. Be sure you pick the right disks to add to the array. Assuming you copied your data to a temporary drive, go ahead and setup your array with your two data disks. And be sure the disk you assign to the array is the one you want to delete!
If you plan to copy your physical installation of Windows to a Virtual Machine so you can boot and use it later, be sure not to assign your OS SSD as the cache device at this point.
Once you get it all configured, start the array. Now that the Array is started, you can setup your shares. This plugin makes that easy. Find the disk that contains your source data. The mount location will be listed e. The main thing here is to make sure the copy is identical — that the dates and times of the files, folders, and relevant attributes get copied correctly. Use rsync to copy the data. The nice thing about rsync is that it will pick up where it left off it it gets interrupted.
There are some security basics that are not enabled by default that you should really do. Setup email notifications. Assuming you want to keep your Windows install, convert that physical boot disk to a virtual machine that unRAID can host. If it makes sense for your case, set up a hard drive temperature monitoring script to set your fan speed based on hard drive heat.
Here's how Unraid can super power your home NAS solution. But what makes it so special? In this article, we'll cover Unraid's unique way of storing data and why it's so efficient. We'll also cover some of the other core features that make it the best home NAS and media server. So even a single file could exist on more than one drive.
Because RAID uses more than one drive in the reading and writing of data, there is a performance benefit. RAID also offers a degree of safety.
RAID is still susceptible to catastrophic failure. If you were to lose two drives in a RAID5 array, you might not be able to get any of your data back. This is because the entirety of the data is dependent on the other disks.
If you took out a single drive from a RAID5 array and plugged it into a computer, you won't be able to see anything meaningful because the data is striped. Another consideration with RAID is that the smallest drive limits the size of the array. This can limit how you can upgrade the size of a RAID array. Additionally, it may not be possible to add a single drive and increase the size of the array.
Unraid can be configured to have up to two parity drives. Similar to traditional RAID this will prevent data loss if up to two drives die keeping your data safe. When you write a file to a share in Unraid, only a single disk spins up along with the parity disks to write the data.
So a single file will always only exist on a single drive. Because the data isn't striped across multiple drives, you can take a single drive that was in an Unraid array, plug it into a computer and see what was on that drive. There is a trade-off with storing the data in this method in that the performance for reading and writing data is limited to the speed of a single drive. However, Unraid mitigates against this by allowing you to use an SSD as a cache drive. In Unraid if one of your disks had to die, you could plug in another drive, and it will rebuild the data that was on that drive.
However, if you were to lose more than one drive, you could still plug the remaining drives into a computer to retrieve what's there. This gives Unraid the edge for keeping your data safe. There is a huge reduction in power consumption because all the drives aren't spinning to read and write data. Unraid is also efficient in how you can expand the size of the array. You can add a drive of any size, and it will increase the size of the array by that size, even if it doesn't match the size of the other disks.
As long as you make sure that your parity drive is equal to or larger than the biggest drive in your array, your data will be safe. Under regular usage, like a video playing and a file being written simultaneously, Unraid still barely bats an eye. This shows how efficient Unraid is at managing its resources.
Well, Unraid allows you to have your cake and eat it! Fortunately, Unraid has native support for virtualization so any remaining resources your computer has can be used to run a virtual machine. These allow you to give a virtual machine direct access to a device connected to Unraid such as a GPU. This means you could create a virtual machine used for hardcore gaming and have near bare-metal performance as if it were running directly on your hardware.
Unraid makes it possible to start your home lab or get into gaming using a single machine. In a nutshell, Docker is a container platform which allows applications to run in a secure environment of their own. It's currently the most widely adopted container platform by millions of developers globally, and it provides Unraid with access to thousands of apps. Fortunately, many vendors provide Docker versions for their apps. This is important because it means you won't have to rely on an independent developer to provide updates to future versions of the software as the companies themselves will maintain them.
Having Docker support also means you're not locked into any proprietary applications. Many popular apps are already available such as: Plex OpenVPN Owncloud You're able to turn your NAS into a powerful media server , private cloud-based storage, or file sharing downloader with just a few clicks. Docker on Unraid works seamlessly and provides an unparalleled level of versatility. This means that there's no limit to how powerful you'd like to make your build as long as you've got the budget to match.
If you require a NAS without virtualization or resource intensive apps, you may even be able to repurpose an older computer that you own. This is another advantage of using regular PC parts, as they're more widely available. You can even build a custom machine with used parts to squeeze a more powerful NAS out of your budget.
Just be sure to check Unraid's hardware requirements and compatibility before making your purchases. Not Sold on Unraid? But it is excellent value for money, and there is a day trial you can use to try it for yourself.
Unraid has an excellent community forum that you can use for both support and advice for your build.
How to set up Unraid – 2021 Guide
The USB Creator does all the heavy lifting for you. No CLI and manual disk management! Thus, we will be booting from the USB drive. Folks are using it directly dedicated NAS hardware, and more. Even better is it has an Intel i7 with virtualization support.
Tip: Try and use a USB 2. If you have multiple USB 3. Make sure the USB is plugged in see step 6 above and power on the machine. It suffers from similar problems as Unraid where the ease of use gets in the way of automation and configurability, and general adoption is still low.
How to pass through a drive to a UNRAID VM
It has a free and commercial support offering, with an active community, and is often cited by STHwhere I first heard about it. There is a pattern here with LXC natively supported, but Docker not, maybe old vs. I think of Docker Hub as the modern cloud equivalent of app stores, everybody publishes there, and everybody looks for apps there.
Virtio-FS may eventually change this, but for now I am installing Docker and Samba directly on the host. PVE gives me confidence and reliability in getting the OS installed, updated, and configured.
I will still use NetData for monitoring, Portainer for container configuration and monitoring, and Watchtower to keep the containers updated. I had two basic choices for data migration; copy the Unraid XFS disks to ZFS disks on the same server, or copy the data to the secondary server and then copy it back. For every 1 drive freed, I will need 2 drives for the ZFS mirror, this would mean I need more drives than I currently have.
The alternative is to provision enough for data I want to keep storage on a secondary server, rsync the data from Unraid to the secondary server, install PVE on the primary server old Unraid serverconfigure ZFS pools, and then rsync the data back. I know, a large RAIDZ1 using old disks is risky, but I do have OneDrive and Backblaze B2 cloud backups of my most valuable data, so I was willing to take the chance, and I saved money by not having to buy any new drives.
Copying the data over gigabit ethernet using rsync over SSH adds quite a bit of overhead, and I was maxing out at around 6MBps. Instead I deployd a rsyncd docker containerand rsyncd has no encryption overhead. Table of Contents So what is Unraid? Unraid is an operating system that you can set up on almost any computer and turn it into a robust network-attached storage server.
It also has support for Docker container and virtualization. Allowing you to set up different applications or operating systems like Home Assistant Plex, Ubuntu, and all from 1 single machine. For the Network-attached storage, you can set up multiple drives in an array, and the drive can vary in speed and size.
You can also add more drives to the array at any time without having to reconfigure everything and rebalance your existing data. It also has Parity protection. Allowing to use 1 or 2 drives as parity that can rebuild the data of a failed drive onto a replacement drive.
What hardware can we use with Unraid? That will pretty much depend on what you are going to use the Unraid server for. If you are going to use it as a NAS server, then the requirements are minimum.
You would concentrate more on the number of drives that you want to use for storage. How much is Unraid? Yes, Unraid is not free. It requires purchasing a license that varies in price depending on the number of drives attached to the server.
A Globally Unique Identifier. Premium flash drives from brands like Samsung, for example, will have a Globally Unique Identifier. There are 3 steps to follow. On the first one, you can select what version of the Unraid OS you want to install. You want to download the stable release and also the latest version.

Before moving to step two, you can click on Customize and set up a server name. The server should have an assigned IP address when it connects to your home network. You can set it up here if you would like or assign the IP to the server on your router settings. For step two, the creator automatically selects the USB flash drive that you inserted.
If not, you can choose it from the dropdown. Lastly, for step three, click on Write, and on the pop up that comes up, click on Erase and Write. When the process completes, inject the flash drive from the computer and connect it to the machine where you are setting up the Unraid server.
Build your own home media server
Configure BIOS, start Unraid, and access the web interface For the first part of the installation, you need to have a monitor and a keyboard connected to the server. Once that initial setup is completed, the server can be headless, and you can access the Unraid web interface from any computer. On the first boot, you want to access your BIOS settings and set the boot priority to boot from the flash drive. If you are going to set up virtual machines, you also want to enable virtualization in the BIOS.
Save the changes, and when the machine boots, it will start loading the Unraid OS automatically. When the OS is loaded, it will show you the IP address that you can use to access the web interface from any computer. If you set up a name for the server on the USB Flash Creator, you can also access the web interface using that name that was set up. Previous Next Start a free trial or purchase a license When you access Unraid from a browser for the first time, you are directed to the registration page.
After the registration, you are redirected to the main page to start adding all your drives to the array.
