OpenMediaVault VS yunohost

You might want to consider the previously mentioned MergerFS and SnapRAID, or MDADM and LVM for your setup. OpenMediaVault [https://www.openmediavault.org/ is a solid choice in this regard. Additionally, if you're planning to run something like Proxmox, you could look into deploying Starwind CVM on top of it. Pretty much like in this guide: https://www.starwindsoftware.com/resource-library/starwind-virtual-san-vsan-configuration-guide-for-proxmox-vsan-deployed-as-a-controller-virtual-machine-cvm/ .

So I'm working on a similar setup with an ancient desktop my in-laws were getting rid of. I installed OpenMediaVault directly to the hard drive (it's so old that I assume it wouldn't work too well as a hypervisor), with a 4TB external HDD attached. OMV supports Docker by means of a plug-in and I'm running a Jellyfin container with no issues at all. I'm still manually downloading everything to the HDD but *arr containers are my next step, as well as setting up a gluetun container to route all that through a VPN.

The second is storage. If you need any of the storage sharing, deploy NAS OS as the VM in proxmox, like Starwinds SAN and NAS (https://www.starwindsoftware.com/san-and-nas) or OMV (https://www.openmediavault.org/), or TrueNAS (https://www.truenas.com/). As you mentioned, you need to cross-flash the perc into IT mode and pass through the controller into VM, but you need a separate from the controller drive for proxmox to be able to PCI-E passthrough the card into VM. Then, configure software RAID and reshare the storage to the proxmox via NFS/iSCSI (that will improve your skills in storage stack and storage protocols).

If you want all that in one, I would go with Proxmox and everything else as VMs or containers on it. NAS can also be run as a VM. For example, Starwinds NAS: https://www.starwindsoftware.com/san-and-nas or openmediavault: https://www.openmediavault.org/. I would try to add more RAM for sure though.

I have Open Media Vault installed on a Raspberry PI. I choose that because also wanted to run some docker images and wanted something cheap. However, if you’re not tech savvy I recommend Synology.

Open Media Vault

To build a NAS, you can set up a Linux VM with LVM, ZFS, Btrfs or deploy a pre-built solution like Openmediavault https://www.openmediavault.org/, EasyNAS https://easynas.org/, Starwinds SAN&NAS https://www.starwindsoftware.com/san-and-nas-free to passthrough the direct-attached storage to NAS VM, create a pool, and expose it to your network as SMB or NFS file shares, or iSCSI storage.

1) VMs are out of the question. Your CPU is too old to run VMs. 2) This could be a very powerful firewall, router, and privacy cleanser. Check out OPNsense or pfSense 3) Could definitely run as a NAS! Not a powerful one. An easy one to get started with is Open Media Vault.

Unless you've got another project in mind for your Pi4 (and who doesn't?), I enjoyed (mostly) my time running an OpenMediaVault machine (I was running Plex and a couple of minecraft servers on it). Here's a guide for installing pihole on an OMV machine, and this guy has a TON of useful tutorial videos around all kinds of neat stuff you can do with OMV (as well as initial setup/config vids).

YunoHost, although not Docker-based, is still nice and quite mature.

If you want something like that, then CasaOS is pretty great and i can recommend it, especially for a beginner. There is also Cosmos and Tipi. Yunuhost too but a bit different approach. Oh and Umbrel is a thing...

However you quickly reach the limits of what Umbrel can do, its very basic in its abilities. Of course it depends all on what you (or anyone else) wants to do with it. There is also CasaOS which is very similar to Umbrel but last i compared, Casa offered a bit more features like for example adding your own docker projects easily. There is also Tipi which i must admit i havent taken a closer look at yet. And there is Yunohost which i guess aims at a similar audience but achieves these things differently, still worth mentioning tho.

This looks exciting and definitely something to look out for as an option fkr self-hosting.

Similiar and a little bit more mature is also YunoHost, https://yunohost.org/, or for professional environments, UCS https://www.univention.com/.

I use https://yunohost.org on my Pi, mostly for monitoring other stuff but you can get Nextcloud running just fine with it!

Just FYI it's Very easy to host with https://cloudron.io or https://yunohost.org

Will this app ever get some love from yunohost.org?

I know it's not Docker, but Yunohost is pretty good for ease of use.
