July 6, 20242 yr Long story short - I had some unfixable corruption of my btr file system (caused kernel panic under load; you can see my previous posts of the last couple of years) - I'm standing up a new server with xfs, moving everything over, and repurposing the old one. New server has 4x 10Gbe NIC but they are all auto-negotiating down to 100Mbps. I'm only expecting 1Gbps link-speed given the intervening hardware with a lower practical limit (~600Mbps) due to the temporary network topology. Firstly, is the X540-AT2 chipset supported in Unraid? Secondly, is there anything in my attached diagnostic file to suggest a correctable root cause? diagnostics-20240706-1241.zip
July 6, 20242 yr Community Expert Solution The syslog in the diagnostics show eth0 is only running at 100Mbps. Commonest cause of this is a LAN cable which does not have all 4 internal wire pairs making end-to-end contact (100Mbps only requires 2).

I had the same thought when I had the issue yesterday and I've already ordered some cat8 cables.
July 7, 20242 yr Author Whelp - that was it. Thanks. I'll mark this solved. Solution: Cat8 cable versus (damaged?) Cat6 cable.
