similar to: Really bad KVM disk performance

Hello all, I am new to this list and hope that my mail is not OFF TOPIC. After looking around for 2 months now, to find a solution, I will try it here now. Now the scenario: I bought a new cool dell laptop: INSPIRON 8100, 512MB RAM, NVIDEA GeForce2Go 32MB, 30GB Hitachi hard disk and a DVD. I bought it with WinME preinstalled, because it wasn't possible to get it with linux nor without an

Hi... I have a Dell Latitute with an ATA/ATAPI-5 T13 1321D and it would seem that my disk access is extremely slow. I have the latest updated kernel from RedHat 8.0 kernel 2.4.18-27.8.0. Somehow I think it is related to the UDMA stuff (shows my level of understanding). I have run hdparm and although I think I should at least udma level 5, I have at most udma2 listed. Is this a kernel

I upgraded my Centos 4.7 server last night. Switched from a cheaper 50$ asus motherboard to a Supermicro motherboard. I also, using dd, copied entire 500g SATA seagate drive to new 500g SATA seagate drive so as to have two copies in case something went wrong. Anyway, now I keep getting this error: Nov 21 06:08:33 server kernel: hda: status timeout: status=0xd0 { Busy } Nov 21 06:08:33 server

We run several RH7.2/7.3 servers & recently 2 of them, although still working fine, have started to show kjournald as generally using over 50% cpu% on 'top' - virtually continuously. Free cpu% generally less than 25% now! Both machines are also using software RAID5 EIDE ....... otherwise are standard server installs. Any info on what kjournald is & why it should have recently

Okay, I've been chasing performance for a while now. I have no idea if I should be trying to get better performance or if I'm getting all I can out of my hardware. Here is the information: /sbin/hdparm -I /dev/hdd /dev/hdd: ATA device, with non-removable media Model Number: ST328040A Serial Number: 7BY034XB Firmware Revision: 3.07 Standards:

Hello Folks, We have 2 (identical hardware) busy public 2U rack servers, both have several hundred users & peak email (for example) deliveries at 300/5min during the daytime. Both servers run RAID1 over 2 EIDE disk drives. One server is fine - it never has problems - it is running RH7.3 and CPU loads are normal. The other server has constant disk activity & kjournald at CPU load of

My apologies in advance for asking such an elementary question. I called myself searching the Installation Guide and Deployment Guide, with no success. The situation is that I bought a Lite-On ATAPI iHAP122 that will not burn DVDs unless I use hdparm to turn dma off. I bought that drive because it was a rare beige drive. Until I can find a decent DVD burner and/or get a Windows machine put

I have a workstation with a Gigbyte board and an Intel Corporation 82801EB (ICH5) SATA Controller (rev 02) that's apparently getting bitten by https://bugzilla.redhat.com/show_bug.cgi?id=502499 It's running CentOS 5.4 32 bit, and the user is suffering from high load and sluggish response whenever a disk write of more than a few MB is made. iostat shows the disk at 100%.

I also experienced this problem and the first thing that really helped out was changing the timing in the span line of the zaptel.conf. Change it to look like this (see below) and see if it helps out. I got the error much less after doing this and eventually got rid of the error completely by removing my raid drives, installing an IDE drive, enabling DMA mode on the Hard Drive, enabling APCI in

Hi, Just thought I'd share some test results of mine in case anyone is interested. Basically the tests are siumulating what our product does with files - although the tests do it a lot quicker (not as many files though). The test is to create 1 million files (each containing the text of the file number) spread over a number of directories. The files are then removed in the same manner as

How do I check if the proper sata drivers are being loaded? If they are not what can I do other then rebuilding the kernel? Thank you in advance, Randy _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi All, A couple of days ago I posted a query here about the loss of performance on my backup server after I moved from Red Hat 7.3 to SuSE 8.1. It appears as though, with no hardware or script changes, that my backup process takes 4 hours longer with SuSE 8.1. I'm doing (what I think is) a very simple script that basically employs SMBMOUNT, CP, and DIFF. Like this:

I am running RH 7.3 with kernel 2.4.18-27.7.x. Recently I have added a new 60GB Quantum IDE hard drive to the server. I have set it up as a MASTER on a separate IDE channel. Two partitions on the /dev/hdc are /dev/hdc1, /dev/hdc2 - both using ext3. For more detailed HDD parameters, this is 'hdparm -i /dev/hdc': ----------------- /dev/hdc: Model=IC35L060AVV207-0, FwRev=V22OA66A,

Hi all! While I was having some fun, testing different filesystems at home and making some benchmarks, I hit a bug when running Postmark in an ext3 partition mounted with data=journal. I repeated this test twice and got the same results under Linux 2.5, also it was not found while mounting with data=writeback or data=ordered or under Linux 2.4. I don't know if it's a know problem or

While investigating erratic performance on one our our servers, I'm getting some very odd performance stats coming from vmstat. What initially appeared to be happening is the machine goes into a hard loop in some mod_perl webserver code. Now there still may be an issue with the code, but my code examinations show no possible way this could be happening, but what I'm writing to you

When I copy a file(13Megs) from /home/ to /tmp/, sync takes almost 2 minutes. When I copy the same file to /usr/local/, sync returns almost right away. Both filesystems are ext3 and are on the same harddrive. When sync is running, the harddrive light stays on but I don't hear it doing anything. dmesg doesn't show any errors either. Below is the `time` output for each command. If you

Hi, all, I think I''m missing a concept with import and export. I''m working on installing a Nexenta b134 system under Xen, and I have to run the installer under hvm mode, then I''m trying to get it back up under pv mode. In that process the controller names change, and that''s where I''m getting tripped up. I do a successful install, then I boot OK,

Hello all, this mail is related to a post by Axel Schöner that I found at http://article.gmane.org/gmane.comp.emulators.xen.user/40621 when I was searching the WEB about solutions to my problem. I would like to confirm that VT-d with XEN 3.3 kernel 2.6.18.8 on mainboard Intel DQ45CB seems to be broken.

Hello, I have a cluster with two nodes, with SLES10 as base system. First I powered on one node, and the system is working just fine. Then, when a second node was added, the performance came down pretty bad. Any hints or ideas about this behaviour?
