General :: Disk Operations Freeze Debian
Jan 28, 2010
I have just installed Debian testing on my new desktop and I am not very happy with performance - when I perform a disk intensive operation, e.g. upgrade packages in the system, everything seems to freeze, e.g. changing tabs in Iceweasel takes 3 seconds. I run the Debian on my 3 year old Thinkpad X60 ultra-portable, and I don't have these issues. (every single parameter of the laptop is much worse than the desktop).
I am using the default packaged kernel and scripts.
I run
hdparm -t /dev/sda1
And I got around 96GB/s, which is expected. What else can I try to make it work better?
rzes:/home/ga# hdparm -i /dev/sda
/dev/sda:
Model=WDC WD15EARS-00Z5B1, FwRev=80.00A80, SerialNo=WD-WMAVU1362357
Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }

When I do some copying of files, or any background disk activity with file reading (transcoding a movie, uploading a big file to FTP, virus scanning) all computer becomes so slow, that I hardly can move my mouse, not to mention any productive use. I have SATA HDD, and Intel Quad CPU. I took measures to be sure it is not CPU or memory resource problem. Gentoo, Fedora, Windows don't freese that much on file reading. It is not a filesystem problem, or HDD, cuse I tried exactly this partition with other OSes.
Nice has a minor effect, but is is not enough, and I can't always start Nautilus with another nice level when I want to copy a file. What can I do to lower the priority of disk operations globally, and make apps to share disk thoughtput equally, not the one to occupie the disk until it finishes?

I have a problem with getting my Linux distribution (Debian amd64-bit) to install. Everything works the way it should - from booting a live CD/DVD (any distro) to running the text-based or gui installation right after bootup. Up until the Linux installation gets to the step for detecting my SATA hard disk drive(s), but before (or at the same time as) initiating the partitioning step, it'll freeze/hang my screen and my CD/DVD drives instantaneously - and the only fix is a forced shutdown and/or hard reboot.
I don't know what causes this, but I tried googling online and all that I really found out was that it might be an issue with running 32-bit vs 64-bit installations - but this is not the case; from running Gparted on Knoppix 32-bit or the partitioning step during a Debian 64-bit installation. Also, I read a random post online related to running kernel commands / parameters alongside the installation (e.g. acpi=off or something similar) stating that it might help?
Anyone got any ideas or solutions? I'm a real newbie when it comes to Linux (though, I'm quite knowledgeable when it comes to computers and technology, and Windows) - else I wouldn't be posting in this forum sub-section, hehe. I can't quite get my head around this one - despite trying my best to find a solution online beforehand.

Well, let's suppose the file is very large, say 10 GB of disk space it is consuming. We perform the above steps. Which operations: cp (copying) or mv (moving) will be more efficient and less time consuming? The inode number 1566966 which was pointing to the file in my home directory is now pointing to the same file which is in some other directry, i.e. /tmp/. Isn't the inode value getting modified in some ways to point to the correct location / beginning of the data block on the hard disk? If the the physical location of the data would not change then we would not be able to free up space in our home directory. That means the mv operation is copying the file into some other location. In other words, it is also performing the cp operation first and then deleting the file from its original location, my home directory in the case above. However, when a file is copied it's inode value changes. But the mv operation is retaining the same indoe value. So, how to determine which operation - mv or cp - is more CPU-friendly or more efficient in terms of performance and time taken to perform the action?

I've developed a tiny webserver for home automation out of an ALIX 1D, and based on a debian lenny. It runs very smoothly and is now able to operate quite a lot of different equipment from a webapp. But i'm not sure how I should handle the compact flash, regarding read/write limitations. From what I've read the partitioning should be ext2, which would disallow the journalisation of the system. A utility to 'flatten' the repartition of write cycles exists, would it be relevant to use if the partition is ext2 ?
I will also disable all logging in execution mode (a debug mode will provide the logs). Is there any other parameters I have to take into account for maximum reliability (i.e. does the system randomly write in some files for various and potentially turned off purposes)? As for the mysql database, it's not important data, and it's actually reconstructed every time the server boots. Given this, is there a way to store the db in RAM rather than in a file? I'm not sure it's the right place to ask, but I sometimes see redirection to here from stack overflow.

I have a Ubuntu 10.04 fresh installation on my HP laptop. Installation successful and boot OK. But the desktop randomly freeze. During freeze(about 15s each time), all programs are not responsive. Sometimes I can switch program by click, but program seems locked. How can I know which module cause the freeze?

I received the following error when I got home from work today. If this was a windows environment, my first inclination would be to boot off my dvd and then run a chkdsk on the drive to flag any bad sectors that might exist. But there's a complication for me.

I did a bit of reading and it seems that most people suggest using badblocks to first get a list of badblocks from the drive and save it to a file. Then use e2fsck to then mark the blocks listed in the badblocks file as bad on the hard drive. My problem here is that this drive is part of a RAID5 array that hosts my OS. I wanted to confirm if this was still the correct process.I boot to my Live Debian disk, stop the raid array if it's active. Then run badblocks + e2fsck commands on the drive in question and then reboot.

I installed Debian on my PC with a Acer Stock motherboard (xc600) with amd64 and after the installation finished it told me to remove my installation media and reboot. After reboot I was returned this message ' ERROR: No boot disk has been detected or the disk has failed.'. I have verified with gparted using mint live OS that I have Debian installed on my system.
I got believes that this may have be caused by a broken grub or I need to configure something I don't know how in BIOS.
I will update the topic later..
My installation media was a USB 2.0 flashdrive with a Debian 8.2 Jessie Installer and 9 different Linux distros. I have installed Debian multiple times before on my laptop and never had this problem so I know how to go through the installation process and set the partitions.

I have debian squeeze server at work, acting as gateway, and home computer with debian sid (amd64). OpenVPN is working on server ecure connections from internet. So my home computer is connected to work server via openvpn almost 24/7. Some days ago i faced strange problem - when i make ssh session from home to work, via openvpn connection, i can login to work server, but after any command on remote console i have blank screen and nothing happening on it. Only exit is pressing Enter ~ . In server's auth log are messages about session opening and closing only.When i ssh to server from local network at workplace - via putty or native ssh - it works without any problems. I can do anything.But from home I can only login.

I'm experiencing some weird short freezing issues in Squeeze and / or unstable. Everything works as usual, then the system will freeze for some seconds if I don't do anything, or resume faster if I move the mouse or hit a key on the keyboard. I thought it was a wifi related problem, as I have an intel iwl4965 , here is what I often see in dmesg:
[ 2608.910307] iwl4965 0000:06:00.0: Queue 4 stuck for 2000 ms.
[ 2608.910317] iwl4965 0000:06:00.0: On demand firmware reload
[ 2608.912832] ieee80211 phy0: Hardware restart was requested

I have been searching the forum regarding info about the debian testing going into freeze, but cannot find specific info regarding some of the facts. I understand that after some time the testing version (squeeze currently) goes into "freeze" before it becomes the new stable. Now, what does freeze actually mean? Currently I'm running Squeeze, and updating as the update software suggests, and since first install, I got a new kernel image, some updates to applications I use etc etc. So, when testing goes into freeze, all updates are stopped and only bugfixes are released, am I right? But I'm curious about one thing, for example I have gnome DE with let's say network manager applet 0.8.
So when testing is done with freeze and becomes the new stable - does it include current versions of kernel and programs that were actual during freeze? Will I have network manager applet 0.8 after freeze is gone to stable, or will it revert to... dunnno 0.7.6 version? At this time I have kernel version 2.6.32-5-686 , when I first installed it was 2.6.32-3-686 , so when going into freeze then stable kernel won't be downgraded, right? Btw I'm not using Sid's repositories. Well I least I think I'm not, the sources.list doesn't include sid's repos... Well sid non-free is there.

i'm running debian on a custom-built (no brand) box, which has been up and running for, maybe, 3-4 years with no issues whatsoever. all good parts... asus mbo, athlon, wd hd, etc. lately, every once in a while - like, say, every couple of days - i hear a "beep" from the box and the system freezes... lose the keyboard and mouse, and the display stays up but also freezes (for example, if a videos vid was playing, it would just freeze). have to physically reboot to get the system back. i assume this has nothing to do with the os or any app (although i'm usually browsing with chrome or ff when it happens). not being a hardware guy... can anybody clue me in as to how to figure out what's causing the problem?

My notebook seems to just freeze once in a while sometimes once a week, sometimes once in two weeks, sometimes once in two consecutive days. I cannot for the love of it narrow it down to anything. Granted, I have not followed the logs, but doing so for the first time gave no real results either.

Since I've installed Debian Squeeze, it freezes 2-3 times a day.
Usually the mouse pointer stops working and the screen remains unchanged, but sometimes it become white or distorted and the system halts.
Video is an older Ati 200m chipset (x300) with radeon driver and shared memory.
OS is Debian Squeeze x64
I've tried to modify xorg's settings. I've tried with and without KMS and compositing, different kernel, UXA/EXA/XAA acceleration, etc.
Maybe it was better with XAA, so the freezes reduced to an average of one per a day.
The version number of xserver-radeon-video-ati is 1:6.13.1-2-squeeze1.
The experimental repository has a little bit newer version of the radeon driver, but it depends on other xorg components, so it isn't simple to install and I don't know how to revert to testing/squeeze if I try to install it.

After installation of debian, using the squeeze net-installer, on a HP elitebook 6930P, i get the following error. "non-system disk or disk error"
It is right after boot process, and just when it should load grub. Grub is installed in the MBR. Windows7, is installed as well, and is not an option to remove. (Should not be the problem though).
/ is set with the bootable flag.
The installation went without any issues, and I have actually tried to install twice with the exact same thing.

I'm experiencing constant system freezes, and was wondering which log file to view in order to determine what is causing it. I switched over from linux mint as it was giving me the same issues now being experience on my debian setup.
When my system does freeze, the keyboard is unresponsive (caps lock won't even turn on) and I have to use the power button to get out of it. The only thing that does work is my wireless mouse which I can still move around.

I am Debian Sid user and have some issues with my keyboard. I installed Debian some months ago and my laptop was always plugged on the external screen with external keyboard and mouse. For the fist time I took my pc at school and notice that when I close the lid (hibernate) then open it, I can't use my keyboard because of freeze. The screen turn on but the keyboard is dead. I have to close the lid few time and suddenly it work. Never face this problem before because with the external keyboard there is no issue.
I installed on the another HDD, Fedora, Mint, openSuse and the problem is the same.
I found some tuts like
- Open gksu gedit /etc/default/grub
- Find the line : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
- Change it like this : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash atkbd.reset"

To be more exactly, debian freeze after i come to the loggin scean, I cant move the mouse and i cant wright.
You may say that this is hardwear error but its not, cus i can run grubs singel-user-mode and do whatever i want in the shell.
so my question is, how do i fix this from shell. I think maby I shld change something in xorg.conf but not sure what, and how.

When I try to shut my PC down (press the shutdown button in KDE 4.3.4), the desktop quits, but the console screen does not appear (the CTRL+ALT+F1 screen). Well, technically speaking it appears but only a still (not blinking) cursor is shown, otherwise the whole screen is blank. This means that not only the X freezes but whole system, because the keyboard is unresponsive too. It happend multiple times now, and every time I reboot after such event, some kde rc files (amarokrc, kmailrc, etc...) get deleted due to the automated filesystem check (unclean umount), which means that I have to reconfigure these apps again.
My home partition is on a separate EXT2 partition (this way I have full r/w access from winxp) and every time this is the only one which gets corrupted. The system partition (which is EXT3) is always intact (no fsck starts on boot). I'm using Debian Squeeze by the way.

I newly installed debian squeeze with software raid. The way I did was, as also given in this thread.
- I have 2 HDD with 500 GB each. For each of them, I created 3 partitions (/boot, / and swap)
- I selected the hard drive and created a new partition table
- I created a new partition that was 1GB. I then specified to use the partition as a Physical Volume for RAID. and used for /boot and enabled bootable.
- Created another partition, which is of 480 GB, and then specified to use the partition as a Physical Volume for RAID. and used for /.
- Created another partion and used for swap
Then RAID configuration:
Through Configure RAID menu -> create MD device ->
(2 for the number of drives, 0 for spare devices)
Next select the partitions you want to be members of /dev/MD0. I selected /dev/sda1 and /dev/sdb1 (for /boot)
Next select the partitions you want to be members of /dev/MD1. I selected /dev/sda6 and /dev/sdb6 (for /)
And no RAID for swap partitions
'Finish Partitioning and write changes to disk' --> Finish the rest of the install like normal. Everything is ok now, except I am not sure how to test my raid config. When I pull the power of the HDD, it only boots from one disk. I read in some forum that I may have to install GRUB manually on the other. In Debian Squeeze, there is no grub command. Not sure how to make my software raid bootable from both disk. I configured /boot partitions of both disks to be boot=yes. Not sure whether that is ok.

Has just bought an old Teac CD-C68E cd changer for 2$ and I would like to use all the six drives but debian can't see all just the first. After searching I only found a page of a suse article in which a suse package named "cdload" solved the problem. After that I searched the debian repo but they don't have that package. Tried to search globally, yet no luck. I'm not only interested in that package but everything that makes that oldie working. Here's a spec page of that cd-r.

I scored a Dell poweredge 6300 from a local pawn shop. It has the capability to boot from cd-rom, but apparently not with isolinux, which is what the debian installer cd uses. I was able to boot to UBCD411 (Ultimate Boot CD, which uses syslinux), but didn't see any option to boot to a CD (maybe I'm missing something here?). I tried using the boot floppy from this site. I didn't expect it to work (it's from the Woody era), and it did not. I got a message that says SYSLINUX ver.XXXX CBIOS boot failed. I went to [URL].. and looked for a boot floppy image for Lenny, but apparently it doesn't exist. I did however find the boot floppy image for Etch.
To be honest, even if I did find the Lenny floppy boot image, I'm not sure how to use it to point the system to the installer CD. So, I have two questions:
1) Does anyone know of a boot floppy image for Lenny, or if I could use the Etch boot floppy image?
2) How would one boot from floppy, then point the system to the installer CD?
System info:
(4) Xeon Pentium 2 processors 500 Mhz
(6) UltraSCSI hard drives
(1) SCSI cd-rom drive
(1) SCSI dvd-rom drive
(1) Floppy drive
(1) 10/100 NIC
I'm open to any other suggestions as to how I could install Debian Lenny on this machine.

I just installed Debian (Stable, 5.0.6) for the first time. I had some troubles related to the installation of network and nvidia drivers, but now the system seems to work pretty well. The only problem i'm having is that when I try to use tools like the graphic update or the graphic packet manager, or the graphic tool for adding/removing software, after I write the password they ask me, they freeze, but still seem keeping loading something, as the cursor usually keeps turning, and, on the lower bar of Gnome, something like "Granting rights..." appears (i've the italian version so i don't know if i'm translating well or not). Sometime they freeze before the request of authentication and then nothing happens, sometime they simply don't start. Also, sometime the update manager starts but freezes when i click on the button that checks for new updates.Maybe it could be useful for you to know that I installed the 2.6.32-bpo.5-amd64 kernel because my network had problems with the 2.6.26-2-amd64, could this be a problem? i also installed the last Nvidia drivers, and i think nothing more, just the system updates from the stable repositories.
