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?
View 9 RepliesI have been enjoying Fedora 11 for sometime, and decided to try Fedora 12. All in all it is working, but the boot sequence seemed much slower. I decided to use bootchart to examine the boot process on my old F11 and new F12 installations. The result show F11 booting in ~34 seconds, and F12 booting in ~57 seconds. Interestingly, the first 30 seconds show that only kthreadd, khelper, and ata/0 are running. CPU and disk utilization are both zero during this 30 seconds span, then all of a sudden everything starts loading, CPU and Disk utilization spike up, and ~23 seconds later I get to the login screen. I sent an email to Harald Hoyer about this, and to my surprise he was kind enough to respond. He suggested I check the BIOS to make sure I had disabled the floppy drive, which I did. The problem persists, so I was wondering if anyone here was having a similar issue and if so how they have dealt with it. I have blacklisted the floppy module (just to make sure)
View 5 Replies View RelatedI 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
View 4 Replies View RelatedI 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
View 4 Replies View RelatedI 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.

View 3 Replies View RelatedFor 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.
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?
View 6 Replies View RelatedI 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.
View 1 Replies View RelatedI'm running Lucid and have an annoying problem with Rhythmbox: while playing, it constantly accesses the disk, every 2-3 seconds drrrrd drrrrd. Listening to some silent music is horrible - the output of the speakers is lower than the noise of the local disk.
Maybe relevant settings in Edit->Preferences:
Playback -> Network Buffer Size: 1024 kB
Music -> Watch my library for new files: off
Is there anything else one can change? It can't be that difficult to read a <10MB file into memory right from the start and not touch the disk drrrrd every few seconds?! P.S. I verified by turning off the speakers and start/stop playback - the noise there on playback and not if turned off. Reliably.
I've been having this issue since at least 9.10. I'm randomly encountering disk thrashing and application freezing which lasts around 30 seconds. Some applications seem to encounter this more often than others. Firefox and Picasa are pretty reliable at reproducing the issue. It also happens often when I'm using Transmission. CPU usage is not unusually high during the 'thrashing' sessions. Running iotop hasn't shed any light on the problem either. I was wondering if anyone else has encountered this or maybe someone could give me some clues. I'm running a dell inspiron 530 with ubuntu 10.04 64bit. I have 4gb of ram. Here is my 'df -h' if that is helpful.

My Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.
I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.
Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?
Just the last day or so, I've noticed a long pause when I boot my laptop, with lots of disk activity. dmesg says:
[Code]...
Why would there be a 15-second pause (during which the disk is slammed) between mounting root and mounting swap? During this time I see nothing but a blank purple screen, there are no cycling dots or text scroll. Is this normal and I'm just freaking out over nothing because there's no indicator of progress? GRUB default boot options: quiet splash nomodeset video=uvesafb:mode_option=1920x1200-24,mtrr=3,scroll=ywrap vt.handoff=7
During my last boot something installed itself that is very annoying and I would like to remove it. The upper right side of my desktop has a tab called New Activity and there is a translucent bar across the top. Now when I right click an item on my bottom task bar the menu appears at the very top of the desktop instead of opening just above the icon. This is an improvement? How do I remove this feature?

View 9 Replies View RelatedI just installed OpenSUSE 11.4 - fresh install (no upgrade). However with 11.4 there is a very annoying bug (actually, two of them, but I'll post the other one to a different thread): every few seconds (10 or 15) the system 'freezes' for a split second. anything that is going on (visible) freezes for half a second or so. If you're in the process of moving the mouse, the pointer will stop dead in its tracks for that half second, and then when it resumes (a half-second later) it picks up from where "it would have been" had there not been a freeze (it will jump from one position on the screen to the next, as per the actual movement of the mouse. If I have a window (a terminal window for example) that is scrolling output, the scrolling will stop for the same half-second. I did a quick monitor with 'top' refreshing every tenth of a second, and when this freezing occurs is *seems* to coincide with spikes in the kernel thread 'kworker'. I have a hunch that this *may* be due to new built-in NVIDIA drivers that are in 11.4 that I wasn't using in 11.2 (where I compiled the driver from scratch) as I have seen a few posts about issues with this and the 'nouveau' driver - this is just a hunch. Not that dmesg also reports this log quite frequently:

This is a FAST system (3 GHz and four cores) that is otherwise running IDLE, other than logging into KDE. So it's not a case of high CPU usage or I/O usage. The video card is: VGA compatible controller: nVidia Corporation GT216 [GeForce GT 220] (rev a2). I have installed a basic KDE 64-bit distribution, using NO proprietary repositories - it's essentially and "out-of-the-box" install.
Running openSUSE11.4 KDE I have this problem:
starting vlc gives only 3 seconds sounds, then quits. Message from system: linuxbox kernel: [ 786.386363] ALSA clock.c:233: current rate 0 is different from the runtime rate 44100 All other players like Smplayer
Movie and translation are 32 seconds out of sync. There are 2 ways to resolve:
1. edit all zillion lines of translation (daunting, I couldnt find tool)
2. add 32 seconds of nothing or whatever to the beginning of a video file
No2 may be quicker, but I do not know how.. I am not good with ffmpeg... also, if I want to join some 32 seconds, lets say of my XVid recording, I need to prepare it to be the same as film, so it is also complicated. how to add 32 sec? I tried openShot (couldnt find option). Cinellera is giving me strange errors, about audio codec and something I dont understand... I am confused in using both tools
Sometimes when I type something to run apps on krunner (alt + f2) it gets freeze for about 10 seconds. I say sometimes but sure it happens most of times I use krunner. Other times I write it on but then the app doesn't come up until about 10 seconds...Does someone else have this issue on krunner? KDE 4.4.1, openSUSE 11.2.

We have a weird problem with two PC's running SUSE 11.3. The built in PC speaker beeps every 2 seconds when you are typing.
One of the PC's (an old celeron with intel graphics, 32 bit suse 11.3) has had this problem for at least a year but we don't use the keyboard much. The other one is a Core i5 with nvidia graphics (suse 11.3 64 bit). This machine was fine until it was upgraded from suse 11.2 (with zypper dup).
It is like a torture and is driving us nuts. It only does this in X11 - text mode is fine. It's probably something obvious but we are stumped.
Firefox, pidgin, thunderbird, intelliJ, even emacs!!!, or perhaps it's gnome in general will periodically stop responding. All named except emacs tend to gray out while this freeze is happening.

I recently downloaded openSUSE (gnome) from the main site. I used ImgBurner to put it on a cd and boot it. After I double click the installation on the desktop, it opens then closes after like 30 seconds. I dont know if the ImgBurner did not burn it on the disk properly, or if my computer is just retarded.
