Debian Configuration :: Periodic Disk Activity With System Being Idle
Jan 12, 2011
I keep noticing disk activity every roughly 1 to 3 seconds even though there is "nothing" going on. Of course, I run a number of "system" and "user" application packages - Apache2, MySQL, Browsers (Opera, IceWeasel), an SMB client and server, OpenOffice 3.0RC8 being the most prominent ones. I wonder what might be the cause for this constant disk activity which happens even when none of the applications do any noticeable work at all. Is there a way to determine the process that does those disk read/writes?

I have Karmic installed on three different computers (work, home and laptop), but on my home desktop there is a strange performance problem. During disk activity it sometimes becomes completely unresponsive. The mouse cursor doesn't even move. It actually seems fine when it first boots up, but it gradually gets worse as I use the computer for a while until it eventually becomes completely unusable. I'm only having trouble on the one system.The drive in the system is SATA, and I already checked to make sure DMA was on. It is a x86_64 kernel.I tried adding noapic to the kernel boot line after some googling, but it seemed to have no effect

GNU/linux kernel 2.6, Slackware 12.0
Every now and then, say with a period of one hour, the system begins accessing the hdd and doesn't stop accessing for at least 5 minutes. What can be the reason? Can it have something to do with the swap partition?

I can start/stop it with origami, but I need to know how to run the start/stop commands when the user becomes idle or active.Or, if I can tell if any user logged in with KDM (since I don't want ssh to stop f@h) is active from a script, I can write one that will do all I need.I can edit sudoers if the commands have to be run as the user. There's only one user I'm worried about making happy (it's the one everyone in the family shares)

I just installed Debian 6.0 IA64 on my HP zx6000 and it pegs the CPU's when doing absolutely nothing but sitting at the desktop. I searched around on Google and found that there is a bug report: 537572. I was just wondering what the status was on that. Is there currently a fix or workaround?
zx6000 specs: 2 x 1.50GHz Intel Itanium 2 (Madison 6MB), 8GB of PC2100 ECC, 73GB 10kRPM SCSI, NVIDIA Quadro4 900 XGL 128MB.

I had noticed that my workstation (running debian testing) is having a constant load of about 0.9 (+/-0.1), even while the system is completly idle.The system starts with a normal load and then goes up to about 0.9 within a few minutes and then will stay there forever (well it can get higher, but never lower). This is the load graph after the system runs some time: URL....
I have tried everything I know to find the cultprint but there is no cpu usage and no io usage. I even have disabled the desktop and still have this problem.Also I have tried booting an older Kernel (4.1 and 3.16) with no difference in the load.Here is some information about my system:
Code: Select all» uname -a
Linux localhorst 4.2.0-1-amd64 #1 SMP Debian 4.2.3-2 (2015-10-14) x86_64 GNU/Linux.

Is it possible to install GRUB in the MBR of the only bootable disk in the system, but load configuration and images from another disk?Basically I want to install GRUB on /dev/sda, but menu and images will be under /dev/sdb2.Note: /dev/sdb is not bootable.

I have just created a periodic maintenance schedule for friends using Windows XP, covering tasks needing to be done weekly, monthly, semi-annually and annually. That set me to wondering what maintenance my Kubuntu system needs. What periodic maintenance do you do?

I created a thread about a problem a I had with my hard disk clicking whilst idle little while ago and I may now have stumbled upon a possible solution. The strange thing with the problem is that Ubuntu/Kubuntu didn't cause this problem but Opensuse 11.2 does.
I installed Fedora 13 to have a glimpse of what all the fuss was about and noticed that I had the same problem (hard disk clicking whilst idle ~ every 20 secs or so). Now there's a wiki on this subject and a few bug reports: [url]
Problem Description
Some ATA harddrives perform very frequent head unloads under Linux significantly shortening their lifespans. Root cause
The inactivity timer for head unload is configured too aggressively either via ATA APM (Advanced Power Management) feature or other non-standard means. Such aggressive settings are very fragile to changes in IO pattern and under Linux many such drives unload their heads only to re-load them shortly. Note that this relentless unloading/reloading cycle can also be triggered under Windows by installing programs which can alter the IO pattern (e.g. certain vaccine programs which runs in background).
Now two of the listed models with this problem are basically identical to my model (Dell Inspiron 1520) and basically share the same hardware: Dell Vostro 1500 and XPS 1520.
The workaround listed is to:
set APM to 254
Furthermore, there is a script: Storage-Fixup which can also be downloaded from opensuse software search. Indeed there is a report of this for a Vostro 1500: Gmane Loom
The report suggests looking at: Disk Power Management - openSUSE which lists a method to create a configuration file to management disk power management:
My question is whether I could download the storage-fixup rpm [url] has a description of it and it can be found: Software.openSUSE.org) and install it to (hopefully) solve the issue or should I follow the method given in: Disk Power Management - openSUSE
to set APM to 254:

For months I've been experiencing periodic screen freezes in Debian Jessie. I've tried many ways to debug/fix it without any luck...
I'm running GNOME 3 in Debian Jessie...
Code: Select all$ gnome-shell --version
GNOME Shell 3.12.2
$ cat /etc/issue
Debian GNU/Linux 8
l
On a ThinkPad X60 with a SSD.
Code: Select all$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)
My screen freezes periodically.
By freeze, I mean that the mouse can still move, but everything else behind it is frozen entirelyI can switch to a terminal with CTRL+ALT+F1, it's ... I guess... X or gnome-shell or something that's frozen? Not the whole OS thoughThese freezes last anywhere between 5 or 10 seconds and 3-5 minutesI can't predict when they will occur, but often, after a suspend/resume, they will start occuring much more frequently. Also, they often happen after I enter my password and press ENTER on the lock screen after a resume from suspend. But not exclusively -- they can happen at any other time when I'm doing pretty much anything in GNOME...
Things I've Tried...
When frozen, I've tried to CTRL+ALT+F1, login, and run gnome-shell --replace... [*[When frozen, I can successfully CTRL+ALT+F1 and run `service gdm restart`... with the obvious downside of losing everything I have open. But the screen responds immediately and I can log back in to GNOMEI tried running `Xorg -configure` to generate an /etc/X11/xorg.conf file to edit, but received an error about not being able to generate configuration for multiple screens or something (I can retry and provide the exact error if this is a useful direction to try) is it the gnome-shell freezing? Is it X? Is it a problem with the X driver I'm using?

I have something that is poling my hard drive about every two seconds. It's really not necessary I don't think. I am not sure how to find out what process it is. My memory usage is pretty low and I am not using any swap.How do I go about tracking the culprit down?

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 followed the guideline 'How to use PreUpgrade' to upgrade F14 -> F15. What happened was that after reboot: 1. The screen was a mess ... no readable information 2. No reaction on pressing 'return' 3. The disk led showed no activity, so I reseted the computer after 5 minutes inactivity. The system came up but with F14. I repeated the 'preupgrade' and all messages are in [URL]... but still F14 comes up after reboot. Where have I missed ... eager to get F15

I recently switched to 64-bit Karmic after installing extra memory. I have everything working fine, but I am experiencing an annoying lag in keyboard and mouse response whenever any of the CPU cores briefly jumps to 100% usage, which tends to happen every 10 to 15 seconds, usually caused by firefox.
I'll be typing or scrolling, and there is fairly regularly a hesitation of a second or two in which nothing happens on-screen, and then everything catches up again, ie the keyboard buffer empties to screen or the page scrolls a lot.
I've tried changing the Nvidia driver and the disk iosched elevator, which were the only ideas I could find when searching on this issue.
It seems to me that (a) the CPU usage shouldn't be jumping up like that, and (b) even if it does, it shouldn't affect keyboard an mouse activity to such an extent. This only started happening after switching from 32-bit to 64-bit Karmic.

I understand that Ubuntu typically has some disk activity even when idle, but I believe that I have a problem that I am worried is affecting my disk drive - which has recently become quite loud. The system disk activity light flashes about twice per second, all the time, when idle. iostat shows a Blk_wrtn/s of between 10 and 40. I am running Lucid x64. The system disk uses ext4 for root and ext4 for /home. The disk activity starts before I even log in. There is no disk activity if I drop to the root shell in recovery mode - as seen by no flashing light and iostat writes = 0. I have tried killing my media server processes, Mediatomb and Squeezeboxserver. I have unmounted the ntfs data drive. There is nothing else running beyond the vanilla install to my recollection other the services above that I stopped. How can I determine which process is causing the constant writing? I do not have this issue on my laptop which is running Karmic, and as I mentioned earlier, I think this non-stop activity is damaging my drive.

For about 15 minutes or so after login on my FreeBSD 8.1 (yes, I know its not Linux) the hard drive goes absolutely crazy with activity. So much so that it takes a while for the ls command to read the contents of the directory. But after the 15 minutes or so the disk activity calms down and returns to normal.
Im thinking it is some sort of fsck command, but I am unsure where or how to disable it. The hard drive is connected via sata to the mobo. Im not quite sure what other info I can post to find out what is going on. Just tell me what other info is needed and Ill post it up.

My system decided to crash on me, hard. It was humming along happily for about 2 months and now doesn't boot. If I boot from hard-disk, I get grub. Launching the first kernel choice hangs. I thought maybe the install was corrupt, so I booted from usb install disk. The usb hdd didn't boot; something about an error trying to access /dev/sda . Unplugging the internal disk and plugging in the usb install disk does result in the system booting. Plugging in the internal disk in a running system usb-booted system does not result in the system detecting the disk.
How do I know if the disk is physically broken? This seems unlikely since it does manage to launch grub consistently. Or is this still possible? How can I try to mount whatever is left? The usb install disk doesn't even list the /dev/sd*. Any pointers on how to reformat the drive if it's not being mounted?

I am using Squessze and Gnome. When I try to use the gui System>Administration>Network or Users and Groups I get the error The configuration could not be loaded. You are not allowed to access the system configuration.Everything was working before. I read around a bit. In some cases,it was caused by mismatching group and password files after using the gui. I do not know how to check if they are matching. Of course I do not know for sure that is the problem in my case.

I attempted to do the upgrade from 11 to 12 with the Preupgrade Assistant. Unfortunatly something went terribly wrong. Everything went well, excluding the size of partition error, untill the reboot. I did have to remove two previous installs. Now grub gives me an option to upgrade to Fedora 12. When I select this the screen runs code quickly and the screen goes blank with alot of disk activity. Then nothing. Is there a method of recovering this install? I am fairly new to Linux Administration and I am just knowledgable enough to mess things up.

As i understand, after autofs unmounts disk (network or otherwise) it keeps spinning. It costs energy, so i wonder is there any way to put hard disk to idle state after autofs timeout kicks in?

How can I load packages from the cd? I installed from cd1 which I burned on a desktop, then installed Lenny onto a laptop. Works great, no problems except I have no way of connecting the laptop other than wireless.
I've found the network manager package on the cd, but don't have a clue how to install it. I really need to get the wireless working so I can install package manager, wi-fi radar and some other things. I tried putting the disk back in and thought rescue mode might bring me back to where I could select the individual packages I need, but that didn't work, it just wanted to go through another install. Thought there was a way to select individual packages and add them to the installation.

I have Debian 6 (squeeze), I have also seen this under Ubuntu (can not remember how I fixed it). (has worked in ubuntu 10.10)I can hibernate, but when I switch on the system cold boots (it does not restore previous session).Note suspend works fine. Have looked in /var/log/pm-suspend.log Shows for each block of suspend suspend a block of resume suspend, but hibernate hibernate is not followed by resume hibernate ( I assume that is what is expected.)

We had a server failure this morning because grub was throwing error 15 (file not found). We discovered that the disk had changed names from hd0,0 to hd1,0. Making the appropriate replacements in menu.lst fixed the problem, but I'm still wondering what could have caused the spontaneous name change.
here are some other possibly related tidbits: * the server had been down because of a power loss, but it is behind a UPS so i doubt there is any electrical damage * eth0 also temporarily failed but the system failed over to eth1
My current theory is that when the bios was configuring the hardware the loss of eth0 shuffled around the addresses of the remaining hardware on the pci bus, which somehow caused the hd0/hd1 confusion. The problem is that everything i've read [URL] says that the drive assignment should be based on the way the disk is connected to the motherboard (which in this case didn't change)

I've bought a new notebook. The hard drive won't stop spinning down and then spinning up again during load. I don't want HD power saving, so I disabled it within
1. /etc/hdparm.conf
Code: Select all# -B apm setting
apm = 255
# -B apm setting when on battery
apm_battery = 255
It didn't work. I can still hear the HD spin up. It's annoying in a video game because things just suddenly stop for a second.
2. /etc/udev/rules.d/50-hdparm.rules
Code: Select allACTION=="add", SUBSYSTEM=="block", KERNEL=="sda", RUN+="/usr/bin/hdparm -B 255 -S 0 /dev/sda"
This was also every tip I could find during RTFM.
Other specs:
Acer Aspire E5-521G-88A8 Notebook
AMD A8-6410 APU
4 GB RAM
AMD Radeon R5 2 GB VRAM

A few days ago I upgraded from debian 7 to 8. First I update, upgrade and dist upgrade - change source list and again update, upgrade and dist upgrade.When inserting a USB disk on key, it works okay. When plugging my WD "My passport" backup USB disk it does not work. The automatic mount works, but the disk can be accessed.I tried to do it manually in a format that worked on debian 7..Manual mount fails too.
umount My passport
fdisk -l (to see device name)
mount -t vfat -o rw /dev/sdb1 /media/kuku/usb_mp4
dmesg | tail
