October 22, 200817 yr I am still toying with the free version. The main use for this is going to be video storage so I am testing specifically for stuttering. When I use the onboard 100mb NIC of my A7N8X mobo I can write to "disk2" while watching a movie from "disk1" without stutter. I had a 1000mb realtec NIC I swapped in and I can't do the same. The movie stutters. I then bought an Intel NIC thinking it was a driver issue but have the same results. Any ideas?
October 22, 200817 yr How much data, and how fast are you writing to the disk while reading from the other disk. There is only so much buffering that can be done before one has an impact over the other. How much ram do you have on your machine? You may need to post a syslog so people can get a picture of the hardware installed.
October 22, 200817 yr Sounds like a transport issue ... not a server issue. Do you have all Cat5+/Cat6 and good switches? What is your latency? You need to post actual throughput numbers in order to know where to look. Install bwm-ng.
October 22, 200817 yr Author syslog attached Switch should be OK. In windows I can transfer about a gig a minute? I am linux/unix retarded. I will have to find out what bwm-ng is and how to install. Thanks.
October 23, 200817 yr Author OK I got the bwm-ng but haven't been able to figure out how to run it. I tried to use installpkg and I think it told me it doesn't end in .tgz Directions for dummys?
October 23, 200817 yr Download it from here: http://linuxpackages.cs.utah.edu//Slackware-12.0/Console/bwm-ng/bwm-ng-0.6-i486-1tfn.tgz and run installpkg
October 23, 200817 yr Author OK more stupid questions. Should the file be located on the flash or on the hard drives? Can I do it from a telnet session? Do I need to get to a certain directory first? Sorry......all new to me.
October 23, 200817 yr Author OK...found one of your other posts with a screen shot. I have it running now I think. Just start transferring and tell you what I get? I have eth0 which bounces all over the place when I transfer a file. There are three columns. Just tell me what to do and what to report thanks.
October 23, 200817 yr press the "t" key 3 times, so the type of display is (30s) meaning a 30 second average. Then report the Rx and Tx for eth0 when writing to unRAID, and again when reading from it. Then press q to end bwm-ng. Then start your reads and writes, and while they are running, run: vmstat 5 10 and look at the last column, "wa" in particular. A high value here means your CPU/LAN is waiting for on a slow disk.
October 23, 200817 yr Author on writing the three numbers were around 13000, 270, 813000 on reading the three numbers were around 120, 11700, and 811000 wa on writing went up to 34 once wa on reading stayed at zero.
October 23, 200817 yr Please include the units on the numbers.... without units, there is no way to know what they are. Also, please only report the Rx and Tx for eth0.... not the totals and not the loopback (lo) device.
October 24, 200817 yr Author writing max around 10000 KB/s, 400 KB/ss reading max around 175 KB/s, 17400 KB/ss That help any?
October 24, 200817 yr Good. 10MB/sec writing and 17MB/sec reading. Was the vmstat output the same as before?.... wa=0 while the reads and writes are ongoing?
October 27, 200817 yr Author No wa while writing to UNRAID bounced around all over the place. It peaked at 49, hit 44 once. A couple times in thirties...etc. wa while reading from UNRAID hovered around 50. Not sure why it was different this time.
October 29, 200817 yr Author This what you want? Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on Supports Wake-on: umbg Wake-on: g Current message level: 0x00000007 (7) Link detected: yes
November 3, 200817 yr You said you had good transfer between Windows PCs... was that using SMB or something else? Have you swapped out the patch cable to the unRAID box? Changed ports on the switch?
