July 7, 201114 yr The gigabit connection from my unraid box seems to have dropped out. syslog: http://pastebin.com/hbWYbbPQ Ethtool output: Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: MII PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) Link detected: yes Which to me seems fine? My Netgear WNDR700 has an amber light for that port and I can only get 10MB/s throughput. I've tried swapping out the cable, the cable that's connecting the unraid box to the router works fine with my PC also. I have this mobo with built in gigabit NIC: http://www.zotac.com/pdbrochures/mb/NM10-F-E_NM10-DTX-WiFi(D525)_v1.pdf It was working fine previously, is there anything else I can check? Thanks.
July 7, 201114 yr What if you do a ethtool -s eth0 speed 1000 Does that change the link speed? Can you check with a different router (perhaps borrow one from a friend?)
July 7, 201114 yr Author Tried that already. Just retried for good measure but its still the same. Gigabit is working on my router for other devices, just not unraid.
July 7, 201114 yr Can we see stats for the nic? ethtool -S eth0 While moving things around did you try a different port on the switch?
July 7, 201114 yr Author root@unraid:~# ethtool -S eth0 NIC statistics: tx_packets: 1269478865 rx_packets: 2234096424 tx_errors: 0 rx_errors: 13 rx_missed: 31252 align_errors: 1413 tx_single_collisions: 0 tx_multi_collisions: 0 unicast: 2233968810 broadcast: 127614 multicast: 0 tx_aborted: 0 tx_underrun: 0 And yeh, I've tried different ports on the router.
July 7, 201114 yr The missed and alignment errors suggest it isn't happy. How about: Make sure unRAID and a client are connected using Gb. At the unRAID console, tail -f /var/log/syslog. Write a big file to the server from the client system while watching the console. Any errors?
July 7, 201114 yr Find out which Ethernet chipset is used. Atheros is known not to work and Realtek 8111E has given a lot of trouble. You may need a PCI Gig-Ethernet card.
July 7, 201114 yr Author Its RTL8169sc/8110sc = Realtek 8169 which is on the supported hardware list. Anyway I powerdown my box and router whilst I went to the gym, come back and I have a green light on my router Getting 50MB/s copying from it again!
July 7, 201114 yr Ouch. There are too many fragile routers & switches littering offices these days. Had one myself last week that would intermittently trash connections on four ports, and of course it started right when I upgraded a system. "Known-good" has become a much less useful concept. Anyway, glad you made some progress.
