Hey again! I’ve progressed in my NAS project and I’ve chosen to go for a DIY NAS. I can’t wait for the parts to arrive!

Now I’m a bit struggling to choose an OS. I am starting with 2x10To HDD + 1To NVMe SSD. I plan to use 1 HDD for parity and to add more disks later.

I plan to use this server purely as a NAS because I will be getting a second more powerful server some time next year. But in the meantime, this NAS is a big upgrade over my rpi 4, so I will run some containers or VMs.

I don’t want to go with TrueNAS as I don’t want to use ZFS (my RAM is limited and I’m not sure I can add drives with different sizes). I’ve read btrfs is the second best for NAS, so I may use this.

Unraid seemed like the perfect fit. But the more I read about it, the more I wonder if I shouldn’t switch to Proxmox.

What I like about Unraid is the ability to add a disk without worrying about the size. I don’t care much about the applications Unraid provides and since docker-compose is not fully supported, I’m afraid I won’t be able to do things I could have done easily with a docker-compose.yml I also like that’s it’s easy to share a folder. What I don’t like about Unraid is the cache system and the mover. I understand why the system works this way but I’m not a fan.

I’ve asked myself if I needed instant parity for all my data and if I should put everything in the array.

The thing is that for some of my data I don’t care about parity. For instance, I’m good with only backing up my application data and to have parity for the backup. For my tv shows I don’t care about parity nor backup while I want both for my photos.

After some more research, I found mergerfs and snapraid. I feel that they are more flexible and fix the cache/mover issue from Unraid. Although I’m not sure if snapraid can run with only 2 disks.

If I go with Proxmox I think I would use OpenMediaVault to setup shares.

Is anyone using something like this? What are your recommendations?

Thanks!

    For a pure NAS purpose this is my go to. Serves drives, supports multiple file systems, and has a few extras like a basic web server and RSync built into a nice embedded system. The OS can run on a USB stick and manage the drives separately for the data.

    On the ZFS front, a common misconception is that it eats a ton of RAM. What it does actually is use idle RAM for the ‘arc’ which caches the most frequent and/or most recently used files to avoid pulling them from disk. That RAM though will get dumped and made available to the system on demand though if for whatever reason the OS needs it. Idle RAM is wasted RAM so it’s a nice thing to have available.
