  • Windows Laptop to OMV via Wlan - Speed to expect?


    Thanks for all the input.


    During the last days I discovered faster speeds if I am at a specific spot in the house...so the wlan connection needs to be optimized ;-)


    @draddy, thanks for the tip. I managed to install iperf3. But how do I start it on the server? I tried just "iperf3 -s" on the commandline - but I get "command not found". Do I need to restart the server?
    Thanks for more ideas.
    But overall it seems that the speeds are OK for a not really optimized system :-)
    Thanks.
    Best.

  • Windows Laptop to OMV via Wlan - Speed to expect?

    Hi,


    in the times of USB3 and hight internet bandwith I am asking myself what speed I can expect from my OMV-NAS.


    for transfering files from and to my laptop I get this:
    Laptop to OMV: 8,66 MByte/s
    OMV to laptop: 16,8 MByte/s


    Is this OK? To slow?


    My laptop is Windows 10. I installed my omv as a networkdrive - so I use it as a normal drive in the system. I use Wlan to the router. Wired connection to the server.


    You find my specs of the server below.


    Where is room for improvement?


    Thanks for some feddback.
    Best.

  • How to come back to a "running" shell?

    Hi,


    thanks again for the help here.
    I am just thinking if there is something similar to the screen command (I use this often) for the GUI? Sometimes I do some longer things in the GUI and have to switch of my PC. How can I come back to the showing process (a snapraid fix started in the GUI for example)? Is there a chance?
    Thanks.
    Best.

  • Snapraid + Union. Want to ad new drive. Question

    Hi together,
    I am running OMV 4 with 3 drives in a snapraid+union setup.


    My setup is like this:
    1 HDD 3 TB Data01
    1 HDD 3 TB Data02
    1 HDD 4 TB Parity


    HDD setup omv.PNG


    As you see I am running out of space.
    What is the best way to ad more space - and only get one new drive?
    If I get another 4TB and ad it as Data drive, will my parity-HDD will be to small?
    Should I get a 6 TB and ad it as a Parity, than I get the space of my old Parity as a Data-HDD - right?


    Where do I find an howto for the procedure?


    I would do it like this:
    - MAKE A BACKUP!
    - ad the new drive via storage -> discs
    - whipe the drive
    - ad the drive to snapraid via services -> snapraid -> drives -> chose new drive and chose to put parity and content on it.
    - take out the old parity drive via services -> snapraid -> drives -> Edit -> uncheck everything for the old parity drive.
    - rename and swipe the old parity drive via storage -> discs


    - ad the old Parity-HDD with new name (now Data03) in my union setup via storage -> Union -> Add
    - tell snapraid that it got a new Data-HDD via services -> snapraid -> drives -> Add and check only content and data.
    - resync my setup


    Would this work?


    Thanks for any input.


    Bet.

  • Standby HDD.

    Yes, it is the official OMV - download.
    I just installed it - and now it is working. This is a great help.


    My NAS is somewhere in a closet - and mostly my children are so loud that I can not listen if the drives are spinning ;-)


    So thanks for you info.


    Any idea if I did something bad with this:


    Thanks for you big help.
    Best.

  • Standby HDD.

    Quote from tkaiser

    On Linux and Unix systems there's something called a manual and often more modern info pages. So you simply do man hdparm and info hdparm.

    Ok.
    For man hdparm I get this:
    -bash: man: Kommando nicht gefunden
    Same for info hdparm.
    If I only enter hdparm I get a list with all options.
    Thanks.
    Fabian


    EDIT:
    I tried hdparm -c before...see above... ?(
    So I now figured out that the small "c" means: get/set IDE 32-bit IO setting.


    Did I now set some value?
    I got back this:
    IO_support = 1 (32-bit)


    Is this a problem - should I redo something?
    Thanks

  • Standby HDD.

    Quote from macom

    From cli:
    hdparm -C /dev/sdb


    you need to adjust sdb. Could be sba or sdc or something else.


    Might not work on your system. What platform are you using and how did you connect the drive?

    What is hdparm -c doing?
    Thanks.

  • MergerFS folders not mounted in /sharedfolders

    Ok, here we go.
    I start with post #10.
    The wait script should be like this

    Bash
    #!/bin/bash

    #/usr/bin/wait-for-mergerfs

    for i in {1..5}; do

      if [[ -e "/srv/e7f4be7f-ade2-4e06-a819-58883b226cc3/media" ]]; then

        exit 0

      fi

      sleep 1

    done


    As far as I know everything behind the # is a comment. So I do not care the mergerfs. I use unionFS. I am not sure how similar they are.
    So this one is clear. great!


    After this I go to the wait service

    Here I am totally lost...in general I have no idea what is happening here...just to point out a few:
    In line 3 it is mergerfs again...is this a problem for me? I use unionFS. Ore is it just the name/a variable?
    In line 5 zfs is mentioned. I do not use zfs as a filesystem.


    I stop here...
    I am just afraid to just do what is mentioned in post 10 without knowing what is happening.
    If you say it is safe to just try, I go for it. I have no idea what might happen to my system.
    So the only solution for me right now after a reboot is to add a new share and delete it afterwards again. Than all shares are active and can be accessed normally.
    Still looking for a simpler solution like this:
    Delay docker service start till specific HD is mounted
    Maybe there is something like "restart share"?
    Thank for all the help.

  • MergerFS folders not mounted in /sharedfolders

    Quote from Revers62

    I do not find your message very nice for developers who spend certainly much more time working on OMV than you have to fix a bug.

    I am really sorry for this. I totally did not want to disrespect all the work which went into the plugin or the whole OMV-Project. I am really enjoying it. And I have to say I am happy that I finally find the reason for my problem in this thread. I spend some hours to find a solution myself and tried to find some help in the forum...I just could not nail it down (was not thinking about) mergerFS/UnionFS.
    I will try to understand the solution in post 10 + 27.
    I hate to just type in some things without really knowing what to do...lets see.
    I have the impression that it is getting over my skill...I will report back.
    Thanks for all the input.
    Best.

  • MergerFS folders not mounted in /sharedfolders

    I still do not really know what to do as a permanent fix. The information in this thread is not really straight forward...but maybe I just have to read it all again.


    Is this a known problem?
    Why do people recommend snapraid/unionFS in OMV...this is running into trouble especially with novice users...


    Except of this issue I am really impressed by this system. I am sure I will solve it ;-)
    Hints still welcome.

  • Recommendation for small USV / UPS to work with OMV

    Quote from ryecoaaron

    Power outages don't happen often around me either but plenty of other things can happen. Twice in the last year, electricians have accidentally turned off the wrong circuit breaker. Luckily, we did have a ups in the middle. And at least once, a datacenter tech has accidentally turned off both PDUs in a rack.
    While a UPS wouldn't help the second problem, I would gamble having a UPS than not having one. I wouldn't want to see a datacenter gamble without them either. If you are worried about UPS communications, don't use them. Let the UPS just be the buffer for short outages. At home, I have 8 systems plugged into my UPS. Not all of them have a way to receive the shutdown signal but at least they don't get incorrectly shutdown every time there is a small blip in power.


    Having the UPS is also handy if you want to move your server or rearrange cords. I can unplug my ups for a few minutes to move cables.


    Not really a fair comparison. The bigger the UPS, the more consumption it is going to have (especially APC because they do self tests a lot). If you have a 10 watt system, you probably don't need a 950 VA UPS.

    I think I skipped the idea of an UPS. But if not, which UPS would you recommend for a small system like mine?
    Thanks.
