How to partition and use OMV system disk for user data

  • Hello Community,
    I found OMV before some days an it's nice.
    Debian with a web-based config engine.
    I hate using the Thecus own system on my Thecus because it's too restricted.


    During the installation of OMV I found some points I will later describe them all.


    But first here: Why you are not creating the partitions as you want before you install?
    For my system I wasn't able to boot after install, I think this is because of the system partition was more than 20GB.
    Why it's not possible to do the partitioning during installation?
    Because of the file "\install\preseed.cfg".
    I commented out the whole block after
    # This makes partman automatically partition without confirmation.
    and was able then to do the partman steps as I want:
    Device Size Used Free Use% Mountpoint
    /dev/sda1 479M 39M 415M 9% /boot
    /dev/sda2 6,1G 1,1G 4,7G 19% /
    /dev/sda3 23G 45M 22G 1% /home


    Yes, i have no swap, I think, 2 x 2GB of Ram should be enough for a NAS server.

  • You are right, the OMV ISO does not let you customize the install.
    But you can do an OMV on Debian set-up instead. Install debian with what ever disk set-up you wish than install OMV. Do a search here on the forum for instructions .
    Very easy and customizable . Work very well too.

  • Hello
    vl1969,
    yes you are right, it's possible to install OMV on a previously installed Debian.
    But if you unpack the OMV Iso to a Folder (line an USB Stick), then you can modify the file "\install\preseed.cfg" like I wrote :)

  • Sure, but why bother. I mean you have to unpack ISO, edit file and than pack it back into ISO or on a bootable USB.
    When you can simply do an OS install, and then run couple of command in cli.
    But to each is his/her own

  • Hi, I Just tried doing this 3 times without any success. I followed the directions, but now OMV does not boot. After I resize /dev/sda2 and re-position the linux-swap /dev/sda3 near it using GParted, OMV no longer boots.


    Also, maybe worth mentioning, Im installing this on a 2014 Mac Mini. But I had OMV running on it for months without any problems with installation and usage whatsoever. It's just that I No longer want to be wasting a 500GB SSD on a 2GB OMV install.


    So what am I missing


    Thanks in advance!

  • Hmm, I did the exact solution. Now I have:
    /dev/sda1 12GB
    /dev/sda2 1791MB
    /dev/sda5 1791MB Swap
    /dev/sda3 ..the rest..


    But now I can't boot. I get the following error message on boot. The FAQ in Gparted does not help me.. and not google ether... please help :) [SOLVED see below picture]





    [SOLVED]:
    - Reboot.

    - When the (initramfs) pops up, run "fsck /dev/sda1 -y" and it works like a charm. :)




    Yea, i think the swap-partition needs to be on an extended partition. If you follow the instructions that is what you get..

    Newbie on OMV... not so new on hardware/software in general, started on the "14.400 bps"-era. Windows-guy, eger to learn more linux.
    - pfSense and OMV is my next thing for small office usage.
