#snapraid — Public Fediverse posts

My experience with #OMV #NAS with #RaspberryPi, and using #SnapRAID + #MergerFS, is that while SnapRAID's really cool, it def could not beat real #RAID. My understanding is RAID works on a low/block level so it can achieve redundancy 'in real time' no matter what files you have, but since SnapRAID is in software, it's not only more involved but it also simply could not achieve full redundancy as you will def need to exclude a lot of files (which could render ur redundancy useless, depending on ur use case) and it's also more involved where you might need to e.g. stop a bunch of #Docker containers prior to it doing its thing.

I'm just not sure how to achieve 'real' RAID on an RPi 4 (of varying memory capacities). One benefit of SnapRAID (and MergerFS) is that you could easily implement it with USB-attached disks, which is the 'friendliest' choice for SBCs like the Pi which has no SATA connectivity built-in.

Because I had a conveersation about #backup yesterday at the pool.

trapexit, author of mergerfs, has a collection of IMHO , good and new user friendly howtos over here.

I think I might RMA that one SATA SSD - that SSD is currently setup as 1 of 2 #SnapRAID data drives (there's another identical parity drive), that is then part of a #MergerFS pool.

There are a ton of video guides on how to replace a disk part of a #RAID array for failure/upgrade reasons on #TrueNAS, but not found one for this SnapRAID-MergerFS setup on #OpenMediaVault.

From what I can tell, there doesn't seem to be a graphical option on #OMV to do this easily/intuitively. Might need to look up some written guides/docs to do this safely, so I can send the SSD back, and recover my data on the replacement drive once it arrived.

Hopefully, this written guide should suffice:

I've managed to get #OpenMediaVault working on my #RaspberryPi (running #Raspbian Lite) and the performance seems pretty impressive! Despite relying on USB storage for the SSDs.

This is my first time running a #NAS on the Pi, on #OMV, not using #ZFS or #RAID but rather an #Unraid like solution, 'cept, #FOSS called #SnapRAID in combination with #mergerfs (the drives themselves are simply #EXT4).

So far, honestly, so good. I got 2x 1TB SSDs for data, and another 1TB SSD for parity. Don't have a backup for the data themselves atm, but I do have a scheduled backup solution (#RaspiBackup) setup for the OS itself (SD card). It's also got #Timeshift for creating daily snapshots.

I'm not out of the woods yet though, cos after this comes the (somewhat) scary part - deploying #Immich on the Pi lol (using OMV's #Docker compose interface perhaps). I really could just deploy it in my #Proxmox #homelab, and I wouldn't have to worry about system resources or hardware transcoding, etc. but I really wanna experiment this 'everything hosted/contained in 1 Pi' concept.

Installing #OpenMediaVault on the #RaspberryPi so far... has been kind of a headache, despite how it always seemed 'simple' on other people's videos... Kinda wondering if I'm better off, just, setting up #SnapRAID, #mergerfs, and #Samba/#CIFS manually.

I don't think I need #OMV specifically, using the Pi as a simple #SMB share that I also happen to run some #Docker services on, I just thought it'd be neat to finally try out OMV, after having only used and been familiar with #TrueNAS all this while.

Well, while it was busy installing (which I initiated remotely, through SSH), for some fuckin' reason I got disconnected to it and I couldn't reconnect to it through SSH again. Why does this only happen when I'm a million miles away (exaggerating) and have no physical access to it but when I'm literally in the same building, doing the same type of thing thousands of times, everything just.. goes swell to the point that it deluded me into thinking #KVM 's a waste of money :')

After looking more into #TrueNAS Scale, I decided to just stick with #Snapraid + #MergerFS for my Plex Media. I like having the ability to mix and match drives and easily expand my storage.

I have never understood why RAID is so much more popular than SnapRaid.

Has anyone around the #Fediverse used a NAS with #MergerFS and #SnapRAID, rather than conventional RAID setups? I want to hear about its stability and usability in a real-world scenario.

The plan here is a file storage server with up to 14 disks of 16TB each. Other great ideas for this setup are welcome too, I have about 1 week left to orient on how I will configure it.

So I bought #Unraid and only then realized the booting-from-a-USB-stick thing isn't just for ease-of-use and optional, but actually an anti-piracy scheme.

I'm just not going to let my homemade NAS system be dependent on a flimsy USB stick. Guess I'll have to give #mergerfs + #snapraid another go, with #openMediaVault this time.
