  • [OMV8] Error on cpupower.service

    Hi votdev ,


    I am in nearly the same situation. But my machine is not virtualized, I want to use cpupower on a bare metal machine (Lenovo ThinkCentre M90q Gen 5) to reduce power consumption.


    My omv is up-to-date: 8.0.8-1 (Synchrony)

    Code
    root@omv:~# systemctl start cpupower
Job for cpupower.service failed because the control process exited with error code.
See "systemctl status cpupower.service" and "journalctl -xeu cpupower.service" for details.

    So, I had a look at the cpupower.service file:

    and after that I looked at the Environment file "/etc/cpupower-service.conf":

    I do not want a 'conservative' governor, I want a 'powersave' governor. After changing it in the config file manually, the service started immediately.

    But, I see the warning in the file, that its autogenerated by openmediavault and I should not edit this file, because my changes will get lost.


    As soon as I reconfigure the 'conservative' governor, the service doesn't start anymore. So, I was under the opinion that my cpu doesn't support the 'conservative' governor. With the following command it's possible to determine the supported governors of your cpu:

    By the way, I disabled all Boost and Performance modes in the BIOS. So, my assumption was right:

    Code
    available cpufreq governors: performance powersave

    Where do I configure the governor the right way? I do not see any option in the openmediavault webui under 'System > Power Management > Settings'? Do we any other place to configure this option?


    Thanks Hoppel

  • Bridge and VLAN

    ShamanRU If I understand you right, it is possible to create VLANs on a single bridge with your workaround, as long as you do not need untagged traffic to be passed:

    Quote from Krisbee

    hoppel118 AFAIK the way netplan works means your have to create a bridge per VLAN and not VLANS on a single bridge. See this thread: OMV + KVM + VLAN not working

    Is this true?


    Thanks

    sudo ./mac.sh VMNAME

    OK, that looks better:


    What do think about these two messages:


    Code
    qemu: module block-block-dmg-bz2 not found, do you want to install qemu-block-extra package?
qemu: module block-block-dmg-lzfse not found, do you want to install qemu-block-extra package?

    qemu-block-extra is already the latest package:

    Code
    apt install qemu-block-extra

    So I tried to start the new macos vm and saw the following red message block:


    Code
    500 - Internal Server Error
Unable to - poweronKonnte Schnittstellen-MTU auf 'virbr0' nicht erhalten: Kein passendes Gerät gefunden


    After removing the network interface and adding my own network bridge, I see the macos setup guide. ^^


    You are my hero of the day! :)


    So, it installs big-sur. but I would like to install ventura.

    Code
    1. High Sierra (10.13)
2. Mojave (10.14)
3. Catalina (10.15)
4. Big Sur (11.7) - RECOMMENDED
5. Monterey (12.6)
6. Ventura (13)
Big Sur (11.7) - RECOMMENDED

    What do you think about ventura with kvm? Why is big-sur recommended?


    EDIT: I changed the variable from svers="big-sur" to svers="ventura" and now try my luck. But I am still interested in your opinion for Ventura in KVM. ;)


    EDIT 2: Ventura doesn't work:


    Any idea?


    EDIT 3: OK, my server doesn't support AVX2.0 natively. Maybe its solvable with this fix:

    I am unsure...


    Next try "monterey". Looks better:



    OK, had to activate a macvtap network. Until now I only used omv network bridges with my vms. macOS doesn't recognize these omv bridges. macvtap to to omv bridge works.


    Now, it needs two hours:




    Thank you so much!

    It takes the vm name as an input parameter but you might need to adjust some of the variables at the top of the script

    upps... I didn't read your message completely. How does input parameter thing work? Your script didn't as for me the vm name. 'Do I have to hard code it into your script?

    You should run my script. It takes the vm name as an input parameter but you might need to adjust some of the variables at the top of the script - https://github.com/ryecoaaron/scripts/blob/main/mac.sh

    Wow! Is there anything you don't have already done? :)


    Sadly the script didn't work:



    There are 2 error messages:


    Code
    Error: Error when defining a domain from .xml

    and there is also a warning:

  • OMV 6 System | Kernel plugin

    Quote from macom

    You could run HA in a VM using the KVM plugin.

    This is my new setup. It’s perfect! My Server UseCase is mainly NAS and home automation.


    With the KVM plugin it was really easy to build the Home Assistant OS VM. Thanks again ryecoaaron for this plugin! 😉


    Here I described what to do to get HAOS working with KVM on OMV6:

    RE: New openmediavault-kvm plugin
    Hi @STUKguy

    I did this yesterday. I decided to setup Home Assistant Operating System in KVM.

    Here is a good general KVM HowTo: [How-To] Use the Openmediavault-KVM plugin

    • install openmediavault-kvm
    • create two folders (pool and isos) -> chapter 3.1
    • configure pool and isos as storage group -> chapter 3.2
    • network configuration -> chapter 3.3 (If you want to do it right, you want a bridge interface in OMV)
    […]

    …
    hoppel118


    This way I do not need Proxmox anymore. Even LXC is possible with the KVM plugin. Docker runs directly on the OMV host and not in the OMV VM. Even though it’s not an issue, I like to have it that way.


    And the best thing is, that I can use the Proxmox kernel on OMV for my ZFS Raid-Z2. Thank you so much ryecoaaron 😉

  • Auto-Spindown of hdd's does not work on OMV6

    henoobis How did you configure your SMART settings?


    „Power mode: Standby“ in combination with hd-idle is what stopped my disks to spin up:

    • "SMART Check Intervall" is 30 min (1800 sec)
    • "Power mode: Standby" -> Check the device unless it is in SLEEP or STANDBY mode. In these modes most disks are not spinning, so if you want to prevent a disk from spinning up each poll, this is probably what you want.


    These are the default settings:



    The following settings seem to be related to hdparm, so decided to use the following settings:


    • APM: 128 - Minimum power usage without standby (no spindown)
    • AAM: Disabled
    • Spindown time: Disabled



    hd-idle is configured the following way:

    [How-To] Spin-down hard drives with hd-idle

    INTRODUCTION

    If you like to spin-down your hard drives but you’re having trouble in doing so, you’re not alone.

    Not all hard drives like hdparm, the utility used by Debian and OpenMediaVault. There’s an alternative called hd-idle which does the job but introduces another issue: it will eventually fail if you use standby/hibernation on your server, plus other inconveniences.

    Hd-idle has been abandoned many years ago and was left in a buggy state, but we finally have a solution: a…

    My disks spin down after 20 min (1200 sec). My /etc/default/hd-idle looks as follows:

  • New openmediavault-kvm plugin

    Yes, you are right! It was possible to create the container. This issue is solved now. Big thanks!


    But... How is it possible to connect to that container? :)



    I determined the ip address of that container on my router.


    It is not possible to log into the container via SSH or to create/establish a console connection via the omv web interface.

    Why are you trying export -i? What is the output of: dpkg -l | grep awk

    Yes, I was a bit quick with my post. I already recognized that it should be an awk option. I edited my last post and installed gawk. Please look at the result: RE: New openmediavault-kvm plugin


    But here is the output:


    Code
    dpkg -l | grep awk
ii  gawk                                 1:5.1.0-1                      amd64        GNU awk, a pattern scanning and processing language

    Hi ryecoaaron,


    thanks for your help. I really appreciate it. Here is the result:


    Code
    export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export LANGUAGE=; awk -i inplace -F":" 'BEGIN{OFS = ":"} /root/{$2="$y$j9T$P4RwUIsVHEID3k9KZSs6J1$eHurABPnULY5g.BnxlWBAce1lKnUQJzE9HtX8QUuyN5"}{ print }' /data/lxc/vbus//etc/shadow

awk: not an option: -i

    The option "-i" doesn't exist.


    awk version and gawk installation:



    Next try:


    Code
    export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export LANGUAGE=; awk -i inplace -F":" 'BEGIN{OFS = ":"} /root/{$2="$y$j9T$P4RwUIsVHEID3k9KZSs6J1$eHurABPnULY5g.BnxlWBAce1lKnUQJzE9HtX8QUuyN5"}{ print }' /data/lxc/vbus//etc/shadow

awk: inplace:59: warning: inplace::begin: Cannot stat `/data/lxc/vbus//etc/shadow' (No such file or directory)
awk: inplace:59: fatal: cannot open file `/data/lxc/vbus//etc/shadow' for reading: No such file or directory


    Now I did the following and the export command worked:


    Code
    > mkdir /data/lxc/vbus
> mkdir /data/lxc/vbus/etc/
> touch /data/lxc/vbus/etc/shadow

    When I now try to create the lxc container via the omv web interface, I get the following message:


    Code
    500 - Internal Server Error
Directory is not empty!


    Any further idea? ;)

    /data/lxc/vbus is on my ext4 root filesystem for the moment. So, it shouldn't be zfs related.


    When I click on "Save" the folder structure is created.


    But I can't finish the setup procedure because of error 500. What can be done? Where is my issue?
