RPi 5 OMV NAS - Not recognised by W11

  • Hi cubemin! The problem shared by all of us is that there is little helpful advice from approved channels. If there is, I have been unable to source it. I have an unusable OMV, for reasons I don't understand. So just about anything is worth trying, even if from unofficial guides.


    If you were able to point me to where I might find information which my help me to get my project functioning, I would appreciate it.

  • OMV is open source and free of charge—essentially a gift. Yet some people expect this gift to be handed to them on a silver platter. :-((( You probably think everything worked perfectly for me right from the start when I began using it four years ago. It takes a bit of perseverance and patience. The documentation is good, but you do have to learn the basics of networking and Debian yourself; the OMV documentation can't do that part for you. OMV 8 is based on Debian Trixie. If you're using a Raspberry Pi, you should use RaspiOS, which is also based on Debian Trixie. Perhaps you should spend some time getting familiar with RaspiOS/Debian. The fact that your Windows PC doesn't recognize the NAS could also be due to Windows 11 settings or your router configuration. After all, it works very well for a great many people, myself included. Maybe a pre-built NAS would be the best option for you.

    I think it's particularly important not to rely on unofficial sources when you're attempting to troubleshoot a system, as you risk inadvertently making things worse due to bad advice.


    With that said, I take it your Windows/Mac computers still don't see any shares from OMV? Or are you having other problems as well?


    You've already received a wealth of information and helpful steps in this thread. Help us to help you - by detailing what you've tried so far (step by step) and any errors or unexpected behaviors you see. After all, I don't even know if my and chente's guides to create and share a folder did the trick for you or not.

  • Another hint if you struggle with W11 SMB shares: Try a simple FTP access.
    It's a different protocol and gives you a lighter way to understand shares, user, rights, etc.

    Building OMV8 on an R-PI -> Here.

    Once the build is complete there's a link in the R-PI build guide that continues to the appropriate location in the -> New User Guide.

    If you create your shares in accordance with Creating a Network Share in the New Users Guide, from the server's perspective (OMV), permissions will be open to any user / PC client on the local LAN.

    However, the PC Client must be configured to accept local networking connections. That means your windows 11 firewall / network security needs to see the local network as a private network, NOT as a public network. (A Public network enforces higher security.) This can be configured in Control Panel, Network and Sharing Center, Advanced Network Settings.

    If you have trouble along these lines, where to go, what to do, settings, etc., might I recommend -> DuckDuckgo's AI. This particular AI is private and does not require a login. Ask it your questions in plain English and it will guide you to the right Client settings.


  • Gday crashtest and cubemin. Thank you both for your positive suggestions. I suspect that there is something that happened during the instalation process causing issues. As a reluctant Windows 11 admin in an office of 6 or so computers I am no stranger to getting W11 to see their peers. But my Mac OS laptop cant see the NAS either.


    From the OMV dashboard, the shared folder seems to be correctly depicted, so I'm not sure what is going on. I admit I have trouble in getting my head around how some terms are supposed to be interpreted in respect of brief instructions, but it doesn't stop me trying to learn as I go along.


    In case I have got some issue(s) with programming of the Rpi or something with the (secondhand) SSD, I am starting from scratch again with new OS SD card and new SSD sata card.


    And Misha, as a student you should appreciate that important part of learning is being hands on, and never giving up.

    I admit I have trouble in getting my head around how some terms are supposed to be interpreted in respect of brief instructions, but it doesn't stop me trying to learn as I go along.

    Regarding the doc's, I wrote a number of them. In the writing, some PC knowledge had be assumed. (Things like, "connect a power cord, keyboard," etc., were out of the question.) Excessive detail could have easily derailed the overall effort. The intent was to provide what was necessary, and no more, for the broadest cross section of likely OMV users, to get them started. As it was, in the first iteration, the User Guide was some 87 standard pages. Even among absolute beginners, encyclopedic style volumes would not be read. (On the unabridged side of writing, "TLDR" also applies.)

    In that case, I'll assume you know something about permissions. Again, if shares are configured as laid out in the Guide, permissions should not be a problem. However, OEM versions of Windows can be locked down by the PC OEM. To "help us" a number of OEM's only like to allow web browser connections.
    ________________

    Note that routers, other local network security devices / appliances and local DNS could be an issue.
    When it comes to security, SMB uses specific port numbers to establish client server connections.

    TCP 445 - SMB over TCP

    TCP 139 - SMB over NetBIOS

    Some users, with Linux and Mac clients prefer NFS. I've looked at NFS and decided not to cover it. It's another animal altogether that has varying issues among the distro's of Linux and versions of Mac OS. (Adding to that, I don't have a Mac.)

  • Hi Crashtest! Many thanks for directing me to the New Users Guide. I can already see a couple of areas where I may have caused issues. Until you mentioned it, I had no idea the guide was available. I will follow it closely when the new Sata SSD arrives. I also found the article on permissions interesting.


    For workgroups, Windows doesn't specifically require "permissions" for peer to peer computers. It will occasionally ask for an email address and a password, but generic inputs seem to be accepted. We have a list of settings which require modification for each particular computer to join the workgroup. But the term "permissions" does not seem to be appropriate.


    Again, thanks for the comprehensive advice.

  • Hi Crashtest,


    Reading further in the installation guide, is there any specific reason to use putty rather than just establishing an SSH session direct from the command prompt?

  • Hi Crashtest, Somewhere else in this forum, I got rubbished for saying that Debian Trixie was not supported. But reading the installation guide, I see


    Debian Trixie is not, currently, supported by OMV7. Use Debian Bookworm, in accordance with the install procedure following.That is for a SBC such as Rpi 4 that I plan on using.

  • It is not "somewhere else" but this thread and you don't get rubbished but corrected in a very straightforward manner because the statement is absurdly false. What you write is not in the document that people linked for you to work through. You are using the old document for OMV7 and not OMV8. Please just follow the link that people sent you multiple times and for your first install do what is being written. You will get a functioning system! The guides are brilliant and easy to follow.

    Installing OMV8 on a Raspberry PI


    Draft: 22 Dec 2025

    Revisions: N/A


    Introduction

    Installing OMV8 on Raspberry PI OS Lite Debian Trixie, using a scripted install, is a relatively easy task. This document is a guide for that process.

    Setting aside that the process and the screen shots use PuTTY, you can use anything SSH client you want, provided that all install steps are followed.


    Debian Trixie is not, currently, supported by OMV7. Use Debian Bookworm, in accordance with the install procedure following.That is for a SBC such as Rpi 4 that I plan on using.

    This is true.

    OMV7 is permanently married to Debian Bookworm. If you install Raspberry PI OS lite, Bookworm, you'll get OMV7. (I believe this may still be valid. However, note that SBC's are officially supported in the latest version which is, currently, OMV8.) OMV8, the current version, is permanently married to Debian Trixie.

    The Raspberry PI OS Lite distro you start with will determine the version of OMV that is installed.

  • Gday erbenzaeler. I couldn't find any reference in this thread to your name. But if I did read it, I would have moved on, as I don't know what omv-extras are, or why I might need them. So I would have moved on. What are "omv-extras" anyway?

    The third party plugin repo that I started that has almost 40 additional plugins including they very popular compose (docker), mergersfs, kvm, and zfs plugins.

    omv 8.5.11-1 synchrony | 7.0 proxmox kernel

    plugins:

    omvextrasorg 8.0.3 | kvm 8.3.4 | compose 8.2.2 | cterm 8.0.4 | borgbackup 8.2.1 | tempmon 8.0.5 |

    mergerfs 8.0.2 | scripts 8.0.6 | writecache 8.3.0 | backup 8.1 | kernel 8.1

    Please don't PM for support... Too many PMs!

  • Help! Anyone! I decided to start again with the same hardware, but a blank SSD for storage and a new newly flashed SD for the system. Carefully followed every instruction in the Install Guide. Booted and logged in with SSH. Followed the guide faithfully, but when I got to the PI OS updates and upgrades, the following line wouldn't copy and paste at the Pi command prompt in the SSH (and PuTTy) window. So I typed it in.

    wget -O - https://github.com/OpenMediaVa…ipt/raw/master/preinstall | sudo bash


    Got a wget: missing URL error. In the previous attempt No1 it must have worked because OMV did install albeit it with some erors.


    Can anyone suggest what I can do to proceed?

    PS: the O in the action line is obviously a capital O not zero.

    • Official Post

    The command line is:

    wget -O - https://github.com/OpenMediaVault-Plugin-Developers/installScript/raw/master/preinstall | sudo bash


    Got a wget: missing URL error. In the previous attempt No1 it must have worked because OMV did install albeit it with some erors.

    wget requires a network connection. "Missing" can happen for a number of reasons; net congestion, busy, etc. Try it again.

  • Thanks crashtest! I did eventually figure that out (my fault), so just in case I had screwed things up, I re-flashed the SD card and went through the official procedure again. This time I got as far as the Install OMV Section. This confused me, as the next command was to install OMV using the same git-hub command as in the section immediately prior.


    "Follow the official procedure" was the recommendation from previous advice, even when is says to repeat a completed procedure? I thought not, so I jumped over it and when to the First Time Login procedure. I re-checked the DHCP IP address, but when entered into the URL line of the browser, I got the URL not found.


    I just cannot see where I went wrong. Any ideas?
