June 9, 201115 yr I have a new unraid build with version 5.0b6a and the following specs: Processor: AMD Phenom II X4 Motherboard: Biostar A780LG3 Ram: Kingston 2 GB DDR3 1066 Power Supply: Corsair CX500 HDDs: 2x 2 TB Seagate LP(1 parity, 1 data) 1x 2 TB Samsung F4 (data) 1x 1 TB Hitachi Deskstar (cache) I have flashed the latest firmware for both the Samsung and Seagate HDDs. I did 2 preclears per drive. Everything started just fine. I assigned my drives and created my shares without an issue. I had no problem transferring files to the array at 90-100MB/s(prior to parity). With parity, I can still write to the cache at 80 MB/s or directly the array at 30+MB/s. My problem is with transferring from the Unraid server to my Windows machine. I can transfer from other places in my network just fine. I'm getting less than 1 MB/s from the Unraid server. I have attached the syslog, results of ethtool eth0 and the disk performance test from unmenu. root@Tower:~# ethtool eth0 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 pause frame use: No Advertised auto-negotiation: Yes Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Link partner advertised pause frame use: No Link partner 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 Result of disk speed test: /dev/sda: Timing cached reads: 3186 MB in 2.00 seconds = 1593.32 MB/sec Timing buffered disk reads: 338 MB in 3.01 seconds = 112.35 MB/sec /dev/sdb: Timing cached reads: 3182 MB in 2.00 seconds = 1590.70 MB/sec Timing buffered disk reads: 402 MB in 3.01 seconds = 133.55 MB/sec /dev/sdc: Timing cached reads: 3122 MB in 2.00 seconds = 1560.35 MB/sec Timing buffered disk reads: 340 MB in 3.00 seconds = 113.18 MB/sec /dev/sdd: Timing cached reads: 3096 MB in 2.00 seconds = 1548.24 MB/sec Timing buffered disk reads: 250 MB in 3.02 seconds = 82.82 MB/sec syslog-2011-06-08.txt
June 9, 201115 yr What about Ethernet errors? What do you get from ifconfig eth0 or ethtool -S eth0 after one of your tests?
June 9, 201115 yr Author I don't know what happened but suddenly it's working without changing anything, not even a restart. Those commands showed no errors. I'll check it regularly over the next couple of days to see if it comes back but for now, oddly, it's fine.
