• 6.9.1 network card instability

    • Solved Urgent

    Since upgrading from beta 25 to 6.9.0 (now 6.9.1) I have had my hp nc523sfp network card continually drop out. Initially it appeared there was no rhyme or reason but now its consistently doing it approximately 30 minutes after restarting my server. Card works fine in the mean time. Unfortunately it has rendered my server useless at its primary role. It appears that the card is timing out for some reason and is unable to be restarted.  Any ideas?

    Is anyone able to tell if the new Linux kernel has deprecated support for my card? I have seen a number of issues as a result of upgrading to rc2 is this when the kernel was updated? I'm literally at a loss with this and the only solution appears to be replacing my card with a newer mellanox model. I have had to revert my network to the onboard 1gbit as its the only way I can reliably maintain functionality of my plex server. Its been rock solid since.

    I don't know if you still have your issue at the moment, but I basically encountered a similar issue on 6.8.x with my R720 onboard NIC, it would just drop the eth link and no amout of pounding internet cables in RJ45 ports would fix it.
    I would have to restart the server several time to have what I would call a "good boot" where it doesn't loose connection in the 30minutes-1hour of uptime frametime.

     

    I ended up splurging on a PCIe Base-T NIC, that held flawlessly since.
    Then since 6.8.3, and worse since 6.9, it's my OTHER PCIe NIC, an SFP+ one that started to have this issue.

     

    And know what? NO one, in 10 months, cared enough to take a look at it.

     

    A deal breaking issue, for a server, to randomly loose connection, and no one gives a foo about it.

    SO my call would be for you to take a loss on a PCIe express slot and half a hundred quid+ for a PCIe NIC, or to switch to an other server distro than unraid 6.9, because at this rate it aint gonna be fixed before Unraid 42.0

    You may want to check the HP site if there are known issues with this specific driver version.

    I think I may have stumbled on something whilst playing about with my new cpu. whilst looking through the system temp plugin I noticed that my qlc nic temp was 104 deg C. I have never seen this in system temp before although I have never looked but I'm sure that for some reason the update has now made that a thing and is disabling the card after a while due to over temp. I have read that this will only reset on restart which also lines up with what I have. I have made no hardware changes with the update from beta to stable so I can only deduce its a driver update within the kernel causing this. Anyways I have a 40mm fan on the way to go directly on the nic, In addition to the 2 80mm fans I have cooling the general pcie slots area of my server. I will keep you posted on my results

    update. the new fan is zip tied to my nic. temp has dropped from 104 deg C at idle to a very acceptable 64 deg C under load. no dropped connections as yet with about an hour and a half uptime. looks promising. one small observation though, I'm maxing out at about 900MB/s whereas prior to the update I was running a full 1.04GB/s.  a win is a win though.
