July 5, 201610 yr Unraid Version: 6.1.9 Running Dockers: Plex Installed Plugins: Preclear Disks, Powerdown Package, Dynamix System Statistics, Community Applications, Nerd Tools Hardware: ASUS P9A-I/C2550/SAS/4L Mini ITX (Marvell 88SE9485 SAS controller) Problem: When I attempt to copy files to the share mounted on a Windows host, I get abnormally low performance (~8 MB/s). It continues transferring at this slow rate for approximately one minute, after which point the transfer stalls and I get the error: "Error 0x8007003B: An unexpected netowrk error occurred". At this point, all mounts become inaccessible, and the webui will fail to load. Glancing at the system log in the webui, I see the following: Jul 4 21:24:50 Tower kernel: igb 0000:00:14.0 eth0: igb: eth0 NIC Link is Down Jul 4 21:24:50 Tower kernel: igb 0000:00:14.0 eth0: Reset adapter Jul 4 21:24:50 Tower dhcpcd[1423]: eth0: deleting IP address 192.168.0.101/24 This symptom is persistent. I have attempted powering the system off and on, as well as attempting the transfer from a different system with the same result. Originally the share was setup to use a cache drive and I tried to remove that from the equation by disabling caching for the share. The symptom still occurred. Copying files from the unraid system is incredibly slow as well (~11 MB/s), but these copies eventually complete. The plex docker I use can still play all content from the share on a remote system. Logging into the unraid system via putty, I can transfer files using MC between the different drives/shares without issue (the performance here is normal), and parity checks do not have any abnormal results. This behavior began one day when I came home to find the unraid system inaccessible. Connecting a monitor to it did not have any display, so I was forced to cut power to the system to get back into it. Attached the diagnostic report as tower-diagnostics-20160704-2127.zip Any insight would be greatly appreciated as I have been using unraid on this system for 8 months without issue. Thanks in advance.
July 7, 20169 yr Can't be sure, but it sounds like the onboard NIC has gone bad (they do that!). You might try adding a PCIe NIC, Intel ones are most recommended here. And when you get it, disable the onboard one in the BIOS.
July 8, 20169 yr Author Thanks for the point in the right direction. I looked around for how I could confirm the NIC getting mucked up, and on a random forum I saw the suggestion to try clearing CMOS. That appears to have done the trick for me (not sure how, but I'll take it!)
