May 13, 20197 yr You know how in windows you can configure the NIC to only use 1Gbit and set the duplex statically. Is there a way to do that with the NIC in Unraid?
May 13, 20197 yr 1 GE does not use half duplex (for a long time). The original spec did permit half-duplex with a hub. Hubs have not been produced in many years. Since the advent of switches, 1G-Base-T (Cat 5 twisted pair) interfaces use full duplex. I'm going to guess that most or perhaps even all available interfaces do not support half-duplex 1GE. -- Tom

So I disabled the on-board card and bought a nice Dell card and does the same thing. My house looks like a bomb went off since I started troubleshooting this issue. Test wires all over. Any thing anyone can think of why the Ethernet in my Unraid box would get stuck at 10Mbit and sometimes not even a reboot will bring it back to it maximum speed.
May 13, 20197 yr Author Take a look at this disk to disk copy. I'm just copying files off an old 2TB drive to a larger drive and will remove the older 2TB drive. But the copy just stops in midstream and picks up when it feels like it. Is this a normal reaction when copying files from disk to disk. Maybe I should have used MC in the terminal. frim disk to disk.mp4

Had it installed because I got tired of my expensive electronics getting "zapped" every now and then in thunderstorms and such. The odds of three Netgear hubs and one Blackbox switch bad all at once is pretty slim. Even power cycled once during the copy to see if that would change anything. I have a very funny feeling Unraid just doesn't like my Asus Sabertooth mainboard possibly. Not much else in the equation.
May 21, 20197 yr Author Do these settings have any affect on the issue described above? While copying files it will just drop to 0MB/sec for about 30 seconds then start up again. The only hardware I have not replaced is the motherboard and processor. I've ran extended tests on all my drives, all results came back ok. It is hard to tell when this started but was wondering if these settings have anything to do with copying speeds/processes? Tunable Poll Attributes Tunable NR Requests Tunable MD_Num_Stripes Tunable MD_Sync_Window Tunable MD_Sync_Thresh I could have sworn, a long time ago there was a utility or something you can run that would give you these optimum numbers. Like a terminal utility or something. I remember it taking a really long time to run. Is that utility still around?
