  • Proxmox Spin down HDD

    Professionals have to save costs - e.g. costs for unnecessarily wasted electric power, for unnecessarily worn out hdds, for unnecessarily installed servers and for wasted time while thinking about how to spin down hdds in a server system ;-).

  • Proxmox Spin down HDD

    Well, to be honest: you are obviousy miles away from the needs of a DC - and we were not talking about energy consumption for cooling. For two short backups a week you don't need a server with hdds in standby - just plug in an external disk or a hotplugable disktray and remove it after backup...

  • Proxmox Spin down HDD

    Just my 5 cents:
    Proxmox is a professional system - and no pro would ever seriously think about frequently spinning down hdds in a server system. It doesn't save energy and costs, because the drives will die much earlier when you spin them up and down often. If you don't need a server just don't build and run one, and play with other less power consuming toys.

  • OMV5 in Virtual Box as Production system

    Hi John,
    install pve from their ISO and then install OMV in a vm on the pve host, not on the host itself. I'm just migrating my OMV4-NAS server (that also runs a few Virtualbox vms) to vms in Proxmox - it's fun...

    PS: OMV5 is still beta - better use OMV4 on a production system...;-)

  • WD MyCloud

    Quote from amix

    Having read this thread I am not sure, whether I understood correctly, since I am totally new to WD MyBook: It is possible to run OMV3 on the cheap, low-spec WD MyBooks?

    It doesn't seem to me, that you really read this thread.Reading the threads title should already answer your question.

  • WD MYCloud mit OMV verbinden

    Ich weiß zwar nicht, ob das für OMV auf Raspi verfügbar ist, aber falls ja wäre die Remote Mount Erweiterung aus den OMV-Extras das elegantere Mittel der Wahl.

  • Rsync Jobs Problem

    Quote from votdev

    I assume this too because the error message is exactly the result of that.

    Shame on me guys - you were right: i didn't only delete the jobs, but accidently also the <jobs></jobs> tags.


    Please excuse...

  • Rsync Jobs Problem

    Quote from subzero79

    I am guessing here, I don't have my server to test. But I think you deleted the jobs xml tags editing the config.xml file.

    I deleted everything between <jobs> and </jobs> in the rsync section like Volker wrote in another thread with this error topic.

  • Rsync Jobs Problem

    I get a similar error message, when i try to create a new rsync job:

    Code
    Failed to execute XPath query '//services/rsync/jobs'.
Fehler #0:
exception 'OMV\Config\DatabaseException' with message 'Failed to execute XPath query '//services/rsync/jobs'.' in /usr/share/php/openmediavault/config/database.inc:244

    Deleting the rsync jobs in omv config file didn't help. I found actual jobs in /var/lib/openmediavault/cron.d, and could start them, but they don't appear in the GUI.


    I couldn't find the string '//services/rsync/jobs' in '/usr/share/php/openmediavault/config/database.inc'.


    Any ideas?

    Hi Humbert,


    booting from USB will not necessarily crash the system from time to time - this port in the Microserver G8 is meant for booting a system. But it is very slow. The best way for your purpose is installing the system on a hdd or ssd on SATA5 (the ODD-port) and installing a modified bootloader (GRUB) on a USB-thumbdrive or a SD-card in the internal ports, that makes the box boot from the system disk on SATA5, even when there are (data-)disks on SATA1-4. You'll find descriptions of this method in the web, e.g. https://www.bastelbunker.de/hp…-booten-von-den-odd-port/ (german) or https://www.aroundmyroom.com/2…10t-booting-with-usb-odd/ (english)

    Quote from Heinz Lindemann

    Obwohl die Platten da sind unter Reale Festplatten, ist unter der RAID Verwaltung fehlen sie , RAID Verband kann daher nicht angelegt werden....

    Hat das System die (vorformatierten?) Platten möglicherweise schon unter "Dateisysteme" eingebunden, wo man sie erst wieder aushängen müsste, um sie zu einem RAID machen zu können?


    Wie hast du von 2.x. auf 3.x upgegradet, via apt-get oder per Neuinstallation?

    Hi qkzk,


    have you possibly written the line numbers from "my" source window into your interfaces file?
    Its content should solely be:


    # The loopback network interface
    auto lo
    iface lo inet loopback


    # br0 network interface bridge
    auto br0
    allow-hotplug br0
    iface br0 inet static
    address 192.168.1.5 #example, IP of your server
    netmask 255.255.255.0
    gateway 192.168.1.1 #example, IP of your router.
    dns-nameservers 192.168.1.1 #example, IP of your router and/or an external DNS e.g. 8.8.8.8 for Googles
    pre-down ethtool -s $IFACE wol g
    bridge_ports eth0 eth1
    bridge_fd 5
    bridge_stp off
    bridge_waitport 0
    iface br0 inet6 manual
    pre-down ip -6 addr flush dev $IFACE

    Edit: I made a mistake: there was missing a cr/lf in "my" source window between the last two lines. Please excuse - and try again to reanimate the cat! ;)

    Except it doesn't work as expected for you. You can make any assumptions you like about me, is not going to change or improve your situation. I actually find it hilarious that you think I don't know what's up lol.
    Go get yourself a real switch and stop trying to prove something you are not. You shouldn't be using enterprise equipment if you can't make heads or tails from the info I gave you. If you want to save 3 watts of power on a switch, you are doing it wrong. You are contradicting yourself by using an enterprise solution that has a monitoring SoC that is powered 24x7.


    Now let's stop this right here and move on to do something productive. There are more people that will truly appreciate any help they can get and you are on the way.

    You can make any assumptions you like about me and my setup, it is not going to change or improve your situation. I actually find it hilarious that you think I don't recognize your poor concealment of the fact, that you are not willing or not able to answer my question (lol is for kids).


    Go get yourself real knowledge and stop trying to prove something you are not. You didn't gave me any information, that i didn't already had for years. I actually save (more than) 3 Watts on an unnecessary switch, while i spend them on iLO, what is a benefit for me.


    Now let's stop this right here and move on to do something productive. There are more people that will truly appreciate any help they can get - sometimes fortunately even from you :D .

    Quote from ryecoaaron

    Not everyone (especially those in the enterprise environment) think about saving a few dollars and a few watts. You can buy a energy efficient gigabit switch for $20 and it will consume 3 watts. That isn't a big cost and is a supported config for OMV unlike a bridge.

    Especially those in the enterprise environment should think more about saving a few watts, because they waste power on my cost since private consumers pay much more for power to support the "poor" economy. Wasting power without thinking and without valuable benefit brought us nuclear power plants and unsolveable problems for tenthousands of years...

    Quote from Spy Alelo

    Obviously you don't know how iLO works to prevent the issue, but I'll leave it at that since you seem to be so knowledgeable and capable of resolving it yourself. And thanks for the lesson on a useless bridge config.

    Except for the described little issue my "useless bridge config" works perfectly as expected, even when you negate its use. Because i don't know how and why iLO and/or its port sharing generates this issue i asked you as the HPE-expert. Obviously you also don't know it. That is no serious problem - i can live without an answer. How about you?


    Imagine you ask your mechanic, why your e.g. Chrysler doesn't run in fourth gear although it has five gears, and he answers that he doesn't understand, why you want to use the "useless" fifth gear instead of buying a Dodge with a much more comfortable automatic gearbox, that he would prefer. I have a feeling that you wouldn't sense that as helpful.
    I sensed your answers as unkind, arrogant and not helpful.

    Quote from Spy Alelo

    I don't know why you have bridged the interfaces, but if they are both on the same switch you will have some major issues passing traffic for certain things and iLO would be one of them. You have to realize that the fact that iLO shares a port with the system's NIC doesn't mean it makes the port a switch. I have a feeling that the iLO ARP record may not be passed along or the wrong record is presented to the VMs.
    ...I have a feeling that you may have to explain better why you have created that bridge, but this is the best I could come up with the little information you gave me.

    Because the question was not how you would connect devices, i gave you all necessary information - except the matter of course, that only NIC-port 1 is connected to the external switch. I have the feeling, that you should better just answer "i don't know" in case you don't know an answer.


    BTW: A bridge makes the host with the bridged NICs work as a switch - and another NIC or another external switch and also the additional consumed power are not free of cost...

    A technical question Spy Alelo:
    I run two Windows-7-Virtualbox-VMs on my ML10v2 under OMV3. The VMs with IPs in the same network as the host and iLo are set up to use a bridged network connected to br0, a bridge between eth0 (NIC-port 1) and eth1 (NIC-port 2).
    Why is iLo (on shared NIC-port 1 with own IP) not reachable for the VMs, but for every other machine in my network?
