Hi, I'm getting horrible performance on my samba server, and I am unsure of the cause after reading, benchmarking, and tuning. My server is a K6-500 with 43MB of RAM, standard x86 hardware. The OS is Slackware 10.0 w/ 2.6.7 kernel I've had similar problems with the 2.4.26 kernel. I use samba version 3.0.5. I've listed my partitions below, as well as the drive models. I have a

Hi, I was wanting to run the equivalent of "hdparm -Tt /dev/hda" except on a SATA hard disk. What is the equivalent command for an SATA drive? I was wanting to see what kind of speed I am getting on the SATA drive. thanks, Jerry

I''m trying to get picture from ethloop and gnuplot. But the output seems weird. I still do not know why and want some examples.

Hi there, I'm running a centos 5.2 (with a centos 5.3 kernel) on a box with a samsung 1To green edition, and this disk looks a bit slow to me and it's not recognized by hdparm : # hdparm -iI /dev/sda /dev/sda: HDIO_GET_IDENTITY failed: Invalid argument HDIO_DRIVE_CMD(identify) failed: Invalid argument # hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2252 MB in 2.00 seconds =

Hi folks, I have just installed a PCI SATA controller based on the SIL3112A chipset into my Centos-3 (latest kernel patches applied) system and moved an existing (not the boot disk) SATA drive from the onboard controller to the SIL-based one so I can setup software RAID with two 300GB drives. Kudzu/Linux found the controller and drives straight away and they've appeared as 'hda' and

I'm trying to rsync a 8TB data folder containing squillions of small files and it's taking forever (i.e. weeks) to get anywhere. I'm assuming the slow bit is check-summing everything with a single CPU (even though it's on a 12-core server ;-( ) Is it possible to do something simple like scp the whole dir in one go so they're duplicates in the first instance, then get rsync to

One of our summer interns has stayed on working part time on weekends during the school year.? This schedule presents an opportunity for technical investigations and some needed performance testing.? The last weekend assignment included data rate testing on one specific network pathway. Checking out previous network testing was the first assignment. Some five year old, archived SPARC/Solaris and

Hi all, Here is my setup: Host1 ---> Router ----> Host2 When i run ttcp -t on Host1 while ttcp -r in Host2, the bandwidth that i can get is about 860 Kbytes/s, which is less than 7Mbps. But i am using NIC 10Mbps for all machines. Why is that so? Currently, i am experimenting with the example efcbq. I am using MGEN (a UDP traffic generator) to send 2 flows of traffic (EF and

I have a Dell PowerEdge 2950 and am looking to add more storage. I know a lot of factors can go into the type of answer given, but for present and future technology planning, should I look for a rack of SATA, SCSI, or fibre channel drives? Maybe I'm dating myself with fibre channel, and possibly SCSI? I may be looking to add a few TB now, and possibly more later. What are people

Hi, im trying to install centos 4.4 server cd on a P5VDC-MX using an 80GB sata drive. centos can't detect the sata drive is there a way to make this work? -------------- next part -------------- An HTML attachment was scrubbed...

Hi, The CentOS 4.4 installation doesn't work on a Optiplex 745 because it doesn't support the sata controller. Is there a known work-around? (smaller prob: dvi video doesn't work at install time, vga only) If only we had CentOS 5 :-) Cheers, -- Henk van Lingen, Systems Administrator & DBA (o- -+ Dept. of Computer Science, Utrecht University.

I am trying to use CentOS 4 on this machine and it does not allow me to set DMA to 1, it just says that it is not possible. I have tried updating to the latest release and it still won't work. I have searched for it on Google and there is a thread mentioning the same machine and CentOS, but none of the solutions (-p, -X 12) seem to work at all and there is no "it works!!!!!"

Hi, I have run into the following I bonded 6 NICs on my Cent OS server into a 600MB pipe. I use bond method 4 = dynamic Link aggregation. My Cysco Switch supports this apparently. However I only get increased bandwidth from my MAC by connecting via AFP. However when I connect via SMB I don't. I was told to change the sockect options to the following on my smb.conf file on my fileserver:

Hi all, I need a little help, i am studing htb to control user bandwidth (download/upload) and I made a script as below to test. I am testing using ttcp tool from by linux box to other linux (192.168.200.51). my box <---- Linux = more than 128kbit mybot -----> Linux = get 128kbit But I want to control both ways, what am I missing? script: EXTIF=eth0 INTIF=eth1 TC=/sbin/tc DOWN=128

Last month Mark Williamson sent out a patch to unconditionally enable the trace buffer. I''d like to suggest that his patch be accepted and merged. I have performed some simple benchmarks to quantify the overhead associated with the trace buffer and calls, and found a negligable performance loss due to them. The actual number was .069%, and was gotten by timing a simple cpu-intensive

HI, I am trying to find out why an old slower machineis faster than a new faster machine. I have a RedHat 6.2 server installation, it runs samba and I have been very happy with it. Filesystem is:- [darryl@keg darryl]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/hda6 1.2G 735M 387M 66% / /dev/hda1 40M 3.0M 35M 8% /boot /dev/hdc1

Hi there: As suggested in the docs, I am forwarding a bug report. I have just converted two partitions to ext3 from ext2 without reformatting on my home box. All is not well, however.

we just purchase new I/O card and like to check I/O performance. for sequence I/O performance test we can use "hdparm -t /dev/xxx" bur for random I/O performance test which Linux command I can use? ** our environment does NOT allow install third party software.. Thanks

I need to disable the spin-down on an external USB drive because it spins down spontaneously while in use. The drive forgets the spindown-disable state across power outage so I need to reissue the hdparm command with each boot or hotplug. Where should I put the hdparm command to do this?

Hi there, I'm going mad at this: Asterisk with one HFC isdn card, using the zaptel driver "bristuff" All works ok, but voice coming in/out of the isdn card is out of sync, squelky and disrupted, UNTIL I PUT SOME LOAD TO THE PC, let say launching xwindows. I noticed this: Strong HDD activity = voice is good HDD doing nothing = voice is not good I suppose this could be an
