gaikokujinkyofusho Posted May 2, 2015 Share Posted May 2, 2015 I have heard quite often how slow unRAID is when writing to the server but exactly how slow and this changing over time is something I haven't seen so much on the forum? I have copied about 7TB onto my server, it has been a pretty arduous process but at least the larger files were copying at around 40-50mb/s (not great but ok) until now... now even the large files are crawling along at 8-12mb/s write rates and its unclear to me why? I am still copying through a USB3.0 dock -> laptop -> gigabit network to my unraid server (with 8tb free space, about at the 50% mark) Any thoughts? Quote Link to comment
trurl Posted May 2, 2015 Share Posted May 2, 2015 Sounds like your network may have degraded to 100mb. What do you get with ? ethtool eth0 Quote Link to comment
gaikokujinkyofusho Posted May 2, 2015 Author Share Posted May 2, 2015 Thanks for asking, I meant to mention that I tried copying from the same computer to a new unRAID box an identical large file and it started copying fine, and at a sustained rate of around 50mb/s. I also tried copying from the usb3.0 dock directly to the laptop it was connected to, also a ~50mb/s rate so not the dock I don't think. Regardless, the output of ethtool eth0 was: Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: No Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: pg Wake-on: d Current message level: 0x000000ff (255) drv probe link timer ifdown ifup rx_err tx_err Link detected: yes You seem to be right about the 100mb/s but I don't know how it happened, nor how to change it, any guidance how to chance it back (and what I might have done to make it do this in the first place?) would be appreciated!

trurl Posted May 2, 2015 Share Posted May 2, 2015 Check ethernet cables and ports, both ends. GB ethernet requires good connection of 8 conductors. Quote Link to comment
gaikokujinkyofusho Posted May 3, 2015 Author Share Posted May 3, 2015 Thanks for the help! I had a heck of a time figuring out where the issue was, I would not have thought it was the cable but apparently it was (and glad it was as opposed to my server which, to me at least, seemed the more likely culprit).
