Great content! Professional video, music selection and volume kept it as a pleasant "fill", great B-roll and you're very easy to listen to. This makes your helpful knowledge and content pleasant to listen to over someone who has a grating voice, loud/inappropriate music etc. Love your work.
After watching this video through completely, I noticed the small number of subscribers and views. I was pretty surprised! High quality video, audio, graphics, cuts, and demos. Keep it up!
Wow, it really surprised me when you said this is your first video. This was super helpful and well produced. I think im sold on doing mergerfs and snapraid.
Man this is so amazing to have this kind of comment ! My video is my phone (Pixel 6), the lightning are the few colored light bulbs I found, and the ambient music was free. I have only a few subscribers because it is my only video yet. I have tons of topics to share about, from servers, to development, project management etc... But free time to make them has been spread thin recently with the future arrival of my first baby. I had to move to another flat and all. But promise soon I will make some more on regular basis.
I like how it uses vanilla filesystem and JBOD (just a bunch of disks) ethos. I plan to use mergerfs (plus snapraid) for my primary music library, with syncthing updating a mirror one to a second computer / jukebox. Syncthing is good on this second machine as it also propagates deletes to help me maintain and prune the library.
great video, gave me confidence to go with this solution for my NAS. You’re great and breaking down complex topics and making them approachable and understandable. Thank you 🙏
Great video! Very informative and straightforward with the explanation and setup. Forked the script and got it working in a discord channel rather than slack.
Perfect guide, thank you so much. Since I'm picky about what data goes on which drive I was going to skip MergerFS, but now I see it'd be handy to have it running as a read only drive to share out to media servers and such.
Glad it helped ! Merger Fs still let you decide where to put what somehow. I am not sure but I think you can put a rule that say that if a folder is in a drive, all the subfolders and files has also to be in this drive. Have a look on the doc !
Great video. Hope you make more at some point. A minor point not covered is Snapraid supports as many parity levels as one likes. There's also split parity although the documentation for it is poor. Any reason you chose xfs over ext4 or another filesystem?
Yes. XFS is supposed to be better for large files than ext4. But honnestly the difference is very small. ext4 would have been perfect as well. And yes I will make more videos, just got a baby that came in the middle :D
Thanks for the video, very informative. Was there a reason you installed the packages on the cmd line instead of the omv plugins? both snapraid and mergerfs are available and presnt UI options to manage? (asking as a relatively new user, not a pro!) - only thing I think you missed, when you stated what mergerfs policy you chose, you did not show how you set that? Many thanks!
Hello ! I didn't installed OMV plugins because I don't use Open Media Vault ! I run ubuntu server LTS ! For the policies, I invite you to have a look here as it can depend of your usecase : github.com/trapexit/mergerfs#policies. I used the pfrd policy on creation, for this you need to add category.create=pfrd to your options in your /etc/fstab file. Mine is now looking like : #MergerFS /mnt/data* /mnt/pool fuse.mergerfs allow_other,use_ino,cache.files=partial,dropcacheonclose=true,category.create=pfrd 0 0
@@thenomadcode oops I hadn’t even noticed as i was researching omv and came across your vid, my apologies! Still a good vid though, many thanks for the reply!
Interesting Video. And I did it a one year ago. Bu how to recover from a situation where now the Rpi crashed and need to be replaced by a complete new fresh installation? (I don't have a copy of the old OS SSD.) What is the fasted and correct procedure tin that case ?
Hey ! You might have notice that my data and OS are on separated drives. I have a OS SSD, for the OS and the rest of my data, is on the HDD drives. What I do is very basic, I just regularly save the configuration files present in /etc, in my data disks with a cron task. All the software running on this server are docker images running on a stack, and I have the definition of this stack hosted on a github repo. So long story short, the OS drive can be erased, reset with a fresh os, and then in like 30 minutes, I am able to put back the previous configuration and spin up the software that I use. But nowadays, you can do way better than this, with Ansible you are able to reconfigure all your machine automatically. Immutable distros like NixOS can be also very interesting in order to re-establish your system quickly.
Yes of course ! ZFS is made basically to be able to create logical volume RAID. As I don't need such functionality due to the use of SnapRAID and MergerFS. The 2 choices left where the classical ext4 and XFS. ext4 is very good for general usage purposes It works amazingly well for small files. XFS is better for large file transfers, or I/O operations, and is famous not perform amazingly with small files. This is why I choose ext4 for my system SSD drive, and XFS for my storage drives.
Awesome video this is going to help me a lot. Question that has nothing to do, what do you use to make your diagrams? Thanks for this content, continue that ways!
Hi ! Thank you, I am glad to hear it helped you. For my diagrams I just used Obsidian canvas feature. I take all my notes on Obsidian and their quite lite canvas feature was enough to do it those diagrams :) Otherwise, if I need something more complex I use draw.io or Figma's FigJam. I will try to make another video soon about how to backup your NAS for super cheap ;)
Absolutely not :D My server is here to store my medias, photos and video footage. If one day I can use ECC I will of course, but my current build was made with spare parts from my previous PC, and I was on a budget :D
Thanks for the informative video. But one aspect remains unclear - how to use SnapRAID to recover data when disks are damaged? I would be grateful for an explanation.
Hello ! It is quite easy with the "snapraid fix" command. I invite you to have a look on snapraid documentation for more details : www.snapraid.it/manual
Thank you ! Indeed I should. But as it is not just a test machine and I have a tons of data on it, it could be a bit complicated. Snapraid documentation is very exhaustive about it. You could for exemple, just delete files on a disk, and use snapraid to recover them.
Great informative video. And nice to have an alternative to the raid standard. However, even if this should prove to be more robust than raid, you must still not consider your critical data safe. It sounds like your real problem was lack of backup. Raid (even this version) is NOT backup. Please, Google 3-2-1 backup, to keep your critical data safe. It is not a software, or brand name. It is a mindset
Hey man! I followed your tutorial and it worked but when I reboot my server the mergerfs pool basically unmounts, the hdd is still detected and partitioned, but the pool is gone.
I've particularly dumped raid 5 for mergerfs , Raid 5 gave far more headaches when the drive failed and replacement became a logistical nightmare at times Then i realized the integrity of all the data was no longer important since its just a media server , and only store important data on SSDs in the server instead
But you can have the same problem you had with your previous raid. if you lost one disk, you dont know it and make the sync, the parity will delete the content of that disk, making it unrecovereable, isn't it?
This is a good point, this could be avoid easily by checking that your disks are correctly mounted and a test file accessible before making the parity. Example : On disk 1 you create a test1 file, on disk 2 you create a test 2 file. You check that these files are here before runing the parity and raise an alert if they don't !
This is a very good question ! Technically, I don't see any issue with encrypting on the file level. As long as the file list is visible by MergerFS. As this one is not checking any content, it should not be any issue. For SnapRaid, as it is a parity software, it will treat the files the same way, encrypted or not. As encrypting on the drive level with LUKS or other, this should not be any issue neither ! If you try it, keep me in touch, I'm curious !
174 / 5.000 Hello, I really liked your article about MergerFS + SnapRAID, I would like to know if it is possible to place some cache using an m2 mvme disk? Could you do a little about that?

I've watched 75-100 videos on every conceivable filesystem and non-RAID NAS/drive setup out there. And every single time the answer seems to be "just use Unraid instead."
. I don't know how fast it is to be honest, because it does not really matter. As I do the parity only once every 4 hours, it does not have any impact on system writes speed.
snapraid is not live parity it is snapshot, whereas unraid is live. unraid has major performance issues in terms of their SHFS implementation which cause significant IO wait times and bring your computer to a crawl. Not an issue if you go all flash but if you go all flash, why even use unraid in the first place. Unraid also has major data integrity issues in that it has no method of checksumming. So you can end up in the scenario where a file silently corrupts and the parity implementation they use will never know. checksumming is important because the parity could be wrong or the filesystem could be wrong and the checksummed file acts as the arbiter between the two. When you run a 'check' with unraid if the parity has had any flipped bits / bitrot then it'll report back that its found errors but you have no means of assessing whether the bitrot occurred in the parity, or in the file - with checksumming you could do that. (which snapraid provides)
@@mrpops2ko The IO wait issue can come up with mergerfs as well. More investigation is needed but may be a disconnect between the storage performance and rest of the system. Too much concurrency. In mergerfs I've added thread pinning and ability to change general priority as a work around for now.
Because it is expensive ! You need the mother board that support it ( my case is Mini ITX form factor). Merger fs and snapraid are enough for me ! But as I said, in production server environment, go for raid !
@@hamisgulyas I mean if you want a bitrot from a raid that does not actually check parity, you do you. I'll stick with BTRFS or ZFS. this is not even counting the other advantages like a filesystem that actually knows what space is in use it just scans the in-use block, not the whole storage. Also, it doesn't require server-grade stuff, and server-grade stuff is quite cheap anyway these days. 256 GB DDR4 RAM is quite cheap now. just get the last-generation server equipment and run software raid on it.

I'm absolutely not afraid of "bit rot" as you say, if something deteriorating data wise than you have a bigger problem than your RAID controller. When you buy the latest server grade stuff is not cheap WHEN it's a server. The power consumption is over the roof and keep in mind: most servers come with hardware RAID, so why double the hassle? Software RAID is also using memory & CPU, so why add yet another level of complexity just for the sake of file storage? The more complexity you introduce to your storage stack you have a better chance you screw up something. Seen that, wouldn't do that. TLDR; It's dull to say that HW RAID is a bad solution because you are a ZFS aficionado. RAID technology exists since 1987, ZFS does since 2001. Also, I trust more HW than SW.
Personally, I store photos and videos, but also private files ( Nextcloud), could be text files or other. I like to have the parity check, I just don't need it real time. My homemade Nas has been made by scrapping some parts here and there and was not having HW raid.
If you're losing data with a RAID. That means you're not backing up. I always try to go with the idea of "Two is One and One is none". If I'm building a Raid 5 with 5 drives. Rest assure the plan is to acquire 10 drives in another Raid 5 configuration or a Raid 10 with 4 drives for backup.
