Software :: Disk Accessed When The System Is Idle?

Jun 18, 2010

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?

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?

OpenSUSE Hardware :: Hard Disk Frequent Head Unloads - Disk Clicking Whilst Idle?

Jun 2, 2010

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:

Ubuntu :: Internal Disk In A Running System Usb-booted System Does Not Result In The System Detecting The Disk

Feb 27, 2011

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?

Ubuntu Networking :: Mounting File System Accessed By SSH Tunnel?

Apr 23, 2011

I really like being able to mount remote file systems using the Places > Connect to Server ... tool on Ubuntu 10.10 -- it makes transferring files a breeze.

Unfortunately, the only way to access a particular server at work (call it Server A), is by first SSHing into an intermediate (Server B), which is the only one with a public ip.

My process for transferring files from Server A is currently:

myComputer $ ssh serverB
serverB $ ssh serverA
serverA $ scp file to serverB; exit
serverB $ scp file to myComputer

Needless to say, this gets tiring, and multiple transfers are slow.

Is there a way to mount serverA directly on my computer (by tunnelling through serverB in the background)? Failing that, how about using sftp?

Debian :: Load On Idle System

Nov 2, 2015

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 allĀ» uname -a
Linux localhorst 4.2.0-1-amd64 #1 SMP Debian 4.2.3-2 (2015-10-14) x86_64 GNU/Linux.

Ubuntu :: Run A Program On System-idle?

Ubuntu :: Running Scripts When System Idle?

I'm trying to write a script to run motion when the computer is idle but for some reason the script I found online doesn't work. I tried to write a simple command to put some echo in a file when the screen server starts and stops but this doesn't work also. this is the script I'm using -

Code:

#!/usr/bin/perl
#open (IN, "$cmd |");
my $cmd = "dbus-monitor --session "type='signal',interface='org.gnome.ScreenSaver',member='SessionIdleChanged'"";

General :: CPUs Keep Toggling Between 100%idle And 0% Idle

Mar 22, 2011

When I run top d 0.5 on my machine and I press 1 to enable the SMP View, I notice that all of the CPUs keep toggling between 100%idle and 0% idle.

The odd part is that when a CPU goes to 0.0% idle, I would expect to see one or more of the other columns peek, but they are not.

What is causing this?

Software :: Gnome Screen-saver Does Not Turn On When System Is Idle - FC-11

Dec 1, 2009

My Gnome screensaver doesn't work, although it once did.

I have searched for a solution to this problem but no luck. I am running FC 11 and out-of-the-box gnome. At first the screensaver worked normally, shutting off the screen after 5 mins. Now it does not do so. I found the following command line suggestion in the forums, and it looks like it may point to a problem -- the screensaver is inactive, but how to make it active? I may be misunderstanding the term inactive, of course. Logically, the screensaver would have to be inactive if I am typing a command.

In any case, the query command shows:

Just in case the screensaver really was not running, I tried this command (which I found in another post):

But the query returns the same thing as before.

The only thing I can think of that might be an issue is that using the "appearances" background facility I added a couple dozen pictures that I thought I might use as screen background. Not long after that I discovered that my screen did not go black after 5 mins as expected. Not sure this correlation has any causal meaning, however. I then tried various things, finally returning to the plain (blue) default. That seemed to fix it for a short while, then after a couple of days, the bad or non-behavior returned -- the screensaver does not work.

(update -- I removed all the extra background pics and it makes no difference.)

My system runs all the time, but I don't want the screen to be on all the time.

Ubuntu :: How To Make System Boot Faster By Removing Idle Time

How to make the system boot faster by removing the idle time between 5s to 10s? bootchart attached. It is Ubuntu10.04LTS by the way. One more hint, the screen black out for ~4s after "Begin: Running /scripts/init-bottom... Done." I don't know what is going on during that 4s, but my best guess is there is a way we can get rid of it.

Ubuntu Installation :: 9.10 - Non-system Disk Or Disk Error With Manual Partitions

Apr 9, 2010

This is the third 9.10 install to do this on two different laptops, so wondering what's up...

In both cases, the goal was to leave a large chunk of unpartitioned disk after the Ubuntu partitions, for a second OS install or a filesystem Ubuntu cannot create like NTFS.

When I install with manual partitions, the system can't boot and asks for me to insert a system disk and press any key. When I reinstall telling Ubuntu to "use the entire disk" it then works.

First laptop, first try:

Remainder of the 500GB disk is free space.

Fails to boot, "insert system disk".

First laptop, second try without the /boot partition:

Remainder of the 500GB disk is free space.

Fails to boot, "insert system disk".

"use entire disk" works perfectly.

Second laptop, first try:

Same thing, non-system disk or disk error, insert system disk.

Second try "use entire disk" is currently in progress but I expect the same to happen.

Ubuntu Installation :: Migrate Working Single Disk System To Existing RAID Array Using Disk UUIDs

Aug 1, 2010

I had done a new lucid install to a 1 TB RAID 1 array using the alternate CD a few weeks back. I messed up that system trying to some hardware working that lucid doesn't have drivers for yet, so I gave up on it and reinstalled to a single 80 GB disk that I now want to move over to the RAID array.

I moved all of the existing files on the array to a single folder, then copied all of the folders from the 80 GB disk over to the array with permissions and symlinks (minus the contents of /proc and /sys, which I created empty).

These are the commands I used:

Quote:

p -a -d -R -v -t /media/raid_array /b*
cp -a -d -R -v -t /media/raid_array /d*
cp -a -d -R -v -t /media/raid_array /e*
cp -a -d -R -v -t /media/raid_array /h*

[Code]....

I tried to change fstab to use the 689a... for root, but when I try to boot, it's still trying to open /dev/disk/by-uuid/412d...

So then I booted from the single disk again and chrooted into the array, then ran update-initramfs -u. I got 3 "grep: /proc/modules: No such file or directory" errors, and "cat: /proc/cmdline: No such file or directory"- so I created directory /proc/modules, created an empty file /proc/cmdline, and ran the initramfs update again. Then I tried to shut down, which hung (probably because I was doing all of this from a terminal window in Gnome), so I killed the power after a couple of minutes.

It's still trying to use /dev/disk/by-uuid/412d... to boot.

What am I missing? I assume I just have to change the UUID to mount as root, but I don't know how.

Debian Installation :: Non-system Disk Or Disk Error ?

Jan 22, 2011

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.

OpenSUSE Install :: No Disk Seen When Booting The Disk In Another System?

Jan 2, 2010

My dual proc, dual core Opteron MSI Master2FAR motherboard failed, and I try to boot a disk, used on this board as boot disk, on an Intel based Gigabyte GA-965-DS3. Both systems are x86_64 architecture.

The OS is on both systems is openSUSE 11.1.

On booting the disk on the Gigabyte, the disk is seen correctly by the BIOS, but not by the OS, and there is no /dev/sdX; no /dev/disk/... either. I am taken to a login shell from the ramdisk.

When I just mount this disk on the Gigabyte (booted with the Gigabyte's original boot disk) everything seems fine. No suprise to me, since the disk was fine, and was unmounted gracefully and physically taken off the MSI before the board failed.

I think that the cause lies in the fact that the harddisk controller on the Gigabyte is different from the MSI, and the driver for that controller is not available at boot time.

I have two questions:

- is my assumption correct, or is something else going on?

- if I am right, is there a way to get this disk booting on the Gigabyte (or on another system, for that matter)?

You might want to ask why I want to boot this disk on the Gigabyte in the first place, since I can mount it and see all data on it. I have a reason for that, but telling that story would make this topic too long, and it's too off-topic. Most certainly I will get to that in another topic.

She tried for a couple of times and could not see my website, which the address is accurate.

Are there specific things I need to do to allow users to see my site? Yet, why does she not get messages saying that "failed to access" or something like that?
