• Custom docker network - container fails to start

    Hey all,

    I created a docker network directly on the server via SSH:
     

    $ docker network create vpn

    Then I created a docker entry in the UI, and selected this network from the dropdown successfully.

     

    However, when trying to start this container from the UI it fails to start, but no errors displayed.

     

    Trying to start it via SSH instead shows:


     

    root@Tower:~# docker ps -a
    CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS
    NAMES
    26e0054002b3 azinchen/nordvpn "/init" 5 minutes ago Created
    nordvpn
    
    root@Tower:~# docker logs 26
    
    root@Tower:~# docker start 26
    Error response from daemon: failed to create endpoint nordvpn on network vpn: failed to add the host (vethae07446) <=> s
    andbox (vethc725125) pair interfaces: operation not supported
    Error: failed to start containers: 26

     

    A quick check on the internet suggests this can be an issue with the "veth" module in the kernel:

    root@Tower:~# modinfo veth
    filename: /lib/modules/4.19.88-Unraid/kernel/drivers/net/veth.ko.xz
    modinfo: ERROR: could not get modinfo from 'veth': Exec format error

     

    Thoughts?

    Hold fire on this one, because it's dawned on me that i've installed the unraid nvidia plugin, but have not rebooted yet, which might have left the kernel modules in a non-compatible state with the currently running kernel.

     

    I'll reboot, retry, and then failing that, revert to the normal build, and retry again.

    Will report back (just waiting on array parity to sort itself out before rebooting :) ).

    For future reference, the nvidia and dvb modifications are not supported by limetech. Before filing a bug report, please be sure to revert back to the limetech release and duplicate the issue there. If the issue only occurs with 3rd party modifications you need to bring that up the the folks doing the modifications.

    of course :) it only dawned on me afterwards; my apologies.

    I'll update here once i've confirmed whether there's an issue or not, either way.
