  • TX network traffic when writing data to quantastor server

    Hi I saw some weird issue in the network behaviour of Quantastor and that maybe also causing bad performance.

    I have some nics in my server, eno1 is the 1Gbit Onboard Intel nic.
    enx - are USB connected nics with a realtek driver(2.5Gbe, drivers downloaded and installed correctly - did some time to check out how to correct install that driver).

    everytime when I send some traffic from a Windows client(well, that is virtualized with an ESXi server) to a SMB share, the data is received by an interface and is transceived by either the same or another interface...
    That is weird...

    And actually it does matter to which interface I send the data, the 905-Interface is always transceiving that data.

    When I send data from my laptop, that behaviour does not exist.

    Because of that traffic mess up the performance also is not really good...
    Meaning around 45MB/s from my virtual client and max 140MB/s from my laptop(laptop(with NVME) has 2.5Gbe NIC too).
    My ESXi servers have 5Gbe nic.
    And I have a RAID-Z1(aka Raid-5) Pool with 3 HDD's and some NVME as Write- and Read-Cache, but also another Raid-Z1 Pool with 3 SSD's where get exactly the same performance.

    Is somebody knowing what's going on here?

    Hello,

    Sorry for the delay in getting back to you. Do you have multiple gateways configured? This can cause issues with traffic routing.

    I would recommend using static routes to ensure that the traffic is passed through correctly.

    Kind regards,

      Hey Joshua,

      give me some time to check that... I have an issue that my OS disk seems to have issues, so currently I'm not able to manage my Quantastor.
      Fortunately at least my data share are still accessible.

        Hi Joshua,
        just checked it, I have no multiple gateways set for that system. So that is not an issue...
        How could we check, what's the reason for that?

          Hello,

          Can you upload some logs from the system in question? Any additional information will be helpful.

          Sometimes if routing is not set up correctly, that could lead traffic to go down a specific route, that may not be the route it is intended to go down.

          Kind regards,
          Joshua NB
