[Solved] KDE 4.5.1 constant disk i/o from /jbd2/sda4-8

I recently switched from Gnome to KDE 4.5, and have noticed one small problem, that this machine never had with Gnome.   I put conky on it (and have a disk io graph on my config) and last night I noticed that /dev/sda was being accessed every couple of seconds.   Using iotop I can see that very 2-3 seconds I get disk i/o access from a process called /jbd2/sda4-8.   I have read up on this, and it's got something to do with ext4 journaling.   I took a look at my fstab and noticed that two partitions on /dev/sda did not have the noatime flag, but adding that didn't correct this problem.   Some people say this can be caused by the HAL daemon, but in the Arch guide for KDE it says that HAL is necessary for KDE to automount drives.   One person suggested I try the command hal-disable-polling --device /sda, but when I tried that it just returns a message saying that /sda isn't removable media, and thus, polling wasn't running on it to begin with.   
The only other option I've seen would be to just remove HAL from the daemons entry in rc.conf, but then what would I do about KDE not showing the drives in Dolphin?
Looking over system logs revealed no errors either.   I'm just at a loss to see how to stop this.

ah ha!  I'm an idiot.   I didn't understand how conky could be the culprit, considering I never saw this activity in Gnome.   But just for the sake of troubleshooting, I tried iotop while conky was killed, and the problem was gone.   
Then it hit me.    To set up conky with KDE, and make transparency work, you have to use feh to take a snapshot of the desktop background.   Conky was set to 2 second updates, so therefore feh was refreshing as well!   
I'm just glad I know exactly what the issue was.    This teaches me to double check the simple things first, before thinking of way more complicated things.    Thanks guys.   Marking this as solved.

  • Constant disk activity; who is doing that?

    Hello there,
    I pimped my G5 with two new internal drives (WD 1TB Caviar Black) and copied onto them clones of other disks and volumes (with SuperDuper), including my old system. Seems to be quite succesful operation; nearly all works as usual again.
    Of course I expected mdimport to do some heavy indexing, with constant disk activity as a result.
    But, after a couple of days, there is still constant disk activity: every second or so some 5,99MB is being written to disk, according to Activity Monitor.
    I do not understand which app is doing this, for no one seems to be very busy at all.
    Any ideas out there?
    Appreciated,
    Marius

    I just dealt with this problem effectively on my Mac Pro (Snow Leopard 10.6.4), after considerable mucking around. Hard drive noise, flashing lights, system slow-downs, all driving me nuts (admittedly, a short drive).
    Turned out to be Spotlight. As it happens I have a WD Studio 1-terabyte Firewire drive that's always hooked up. I back up to it several times a day when I'm on a project, and it has clones of my application drive and three data drives, all visible on my desktop. I also have a separate Windows drive that's visible. Recently, for reasons known only to Apple, I'm sure, Spotlight began indexing and re-indexing the cloned logical drives on the WD Studio. Never stopped -- as soon as it finished, it would start again. I simply went into the Privacy tab of the Spotlight preference pane from System Preferences, made sure that all my drives appeared in the box, and then removed all four cloned drives and the Windows drive so that Spotlight would no longer index them.
    Problem solved. If you have extra physical or logical drives beyond those actually in your system (as opposed to Firewire or USB drives), try removing them and re-adding them in the Privacy tab of the Spotlight preference pane. Then wait for Spotlight to re-index the drives -- could take a bit of time, and the drives will keep accessing until re-indexing is complete. If that works, you're good. If it doesn't and the process just keeps going, you might have to remove permanently the external drives and clones from the list of drives to be indexed. That's what I ended up having to do.
    Hope this helps.

  • [SOLVED] KDE I/O not working

    Hello, all.
    I have a wonderful little laptop running Arch with openbox. Earlier today, I decided to install Kate. In usage, I tried to save my file, at which point Kate crashed. I then re-opened Kate, and tried to open a file, and Kate crashed.
    So, I figured it might be a problem with Openbox, so, I installed KDE, and tried to run it in KDE. Well, it turns out, the plasma desktop won't load. It simply loads a white background, starts my programs in the autostart directory, but no desktop.
    Here is a screenshot. I opened Firefox from the terminal (Guake is one of my autostart programs) to demonstrate what happens when I open a window.
    When I initially installed Arch (about a month ago), I first installed KDE, because it was the easiest to install. Everything worked fine.
    A week or so ago, I had customized openbox to my satisfaction, so I uninstalled KDE. Before I did that, KWrite worked just fine. I tried Kwrite today, and I had the same I/O problems.
    The KDE Settings manager also refuses to load properly.
    Here is a screenshot of my vain attempt to run the KDE settings manager in Openbox (It has worked before).
    I found a post on an openSUSE forum with a similar issue. The solution in question did not solve my problem.
    I found nothing searching the ArchWiki or the Arch Forums.
    Basically, I am having trouble even isolating the problem, let alone solving it. Any help would be appreciated greatly.
    Cheers, Metgz.

    Lone wolf: I just re-installed all of KDE, but to no avail.
    If I am not mistaken, the 's' will prevent needed packages from being removed, and, because it proceeds 'c', will override it.
    REMOVE OPTIONS
    -c, --cascade
    Remove all target packages, as well as all packages that depend on one or more target packages. This operation is recursive, and must be used with care since it
    can remove many potentially needed packages.
    -n, --nosave
    Instructs pacman to ignore file backup designations. Normally, when a file is removed from the system the database is checked to see if the file should be
    renamed with a .pacsave extension.
    -s, --recursive
    Remove each target specified including all of their dependencies, provided that (A) they are not required by other packages; and (B) they were not explicitly
    installed by the user. This operation is recursive and analogous to a backwards --sync operation, and helps keep a clean system without orphans. If you want to
    omit condition (B), pass this option twice.
    -u, --unneeded
    Removes targets that are not required by any other packages. This is mostly useful when removing a group without using the -c option, to avoid breaking any
    dependencies.
    hout orphans. If you want to
    omit condition (B), pass this option twice.
    Perhaps I should be using -Runs instead.
    As for more potentially helpful info: I decided to try out various KDE applications to see if they would work. The links go to screenshots.
    Dolphin - No (See a screenshot of Nemo for comparison).
    Konsole - Yes
    Konqueror No
    Kate - No
    KWrite - No
    Plasma desktop - No
    KDE system settings - No

  • Why is there now unusually high, constant disk activity on my Mac?

    Firefox 9.0.1 on Mac OS X 10.6.8 is churning my HD and then must be force quit. It seems to run but there's definately something new and unusual happening here.

    Thanks for taking the time to reply.
    You are right in that there are a lot of guides around to creating "fake" RAC clusters, however Hunter's guide appears to be one of the best and I found it while browsing around the Oracle website. Of course Oracle stress that it is entirely unsupported and for "education purposes" :)
    Well education is what I'm after and I accept that it would perform nowhere near a real cluster. Still the performance issues I'm having appear abnormal.
    The background to this is that one the applications I manage at work (Vmware) has a backend DB hosted on RAC. There is an entire database team who look after this area. For my own personal edification I'd like to learn a bit more about RAC (and Oracle in general) and get my hands dirty, though I currently have no long term aspirations to become a full fledged DBA. I'm working through a text on Safari and I thought it would be useful to create a "fake" as you put it cluster at home and play around a bit. Unfortunately the resources to create a "proper" environment are currently not within my means:(
    With regards to my problem I was hoping someone here has played around with a similar setup and could advise whether they had similar issues. The 3 days or so I spent labouring through the 60 page guide was far more educational than just reading a text.
    I've found that the excessive disk activity appears to be down to my server and Vmware ESXi rather than Oracle. I stopped all instances and CRS and the constant disk activity still continued. I had taken number of snapshots of each linux node during my installation and I'm currently deleting these to see whether this improves things. My hard disk could well be the bottleneck as ESXi is really meant for SCSI controllers and disks if using local datastores.
    I'll take your advice and have a trawl through Ebay. I will also install standalone oracle on a seperate box and have a play with that.

  • T520 Constant disk activity

    T520, 4 GB RAM, 500 GB hard drive, Win 7 Pro 64 bit, 
    Do any fellow T520 users see constant, about one flash per second, hard disk activity. I've turned off the usual suspects, including Windows Indexing Service and all the Intel security and management services and uninstalled Symantec Endpoint Protection 12, which has also been mentioned in certain articles about disk thrashing.
    The side effects of this constant disk activity is that the computer will not enter sleep or hibernate due to inactivity, although I can force it manually.I'm also worried about premature disk wear.
    Any hints would be gretly appreciated.

    HI mixz1,
    I can't answer your question directly, but on my T400 running Win7 Pro 64 I also see the HDD LED flash ~ once per second.  My guess it's monitoring drive status, not actually doing reads or writes.  Even so, the machine sleeps as expected.

  • ServiceLayer.exe and constant disk activity

    Hi
    I wondered what process was causing HD activity every 5 seconds on my system.
    File Monitor from Sysinternals reported that the servicelayer.exe performs a series of disk operations every 5 seconds, continuously. It tries to create a directory, fails because directory exists, opens PCCSConfig.dat, does an query on the file, performs three read operations, one query, one read etc ... until after 9 information queries and 32 reads the file is closed - and after 5 seconds the whole process is repeated. A File Monitor log file is attached showing the constant disk access.
    Is all that constant disk activity really necessary or is it a bug?

  • Constant disk activity on 2 node RAC 11g cluster - Can anyone help?

    Hi Folks,
    My first post on the forum so I hope you go easy with me.
    I'm new to Oracle, and thought that the best way to get into it would be to dive in and build an experimental RAC cluster on my home network. To this end I used Jeff Hunter's "Build Your Own Oracle RAC Cluster on Oracle Enterprise Linux and iSCSI" guide.
    My only departures from the guide is that I've modelled the architecture entirely within Vmware ESXi on a single quad core Opteron server (HP ML115 G5) with 8Gb RAM and a 1 Tb SATA hard disk. I've also used Openfiler 2.3 for the iSCSI storage rather than the deprecated 2.2. I therefore have 2 Virtual Machines running Oracle Enterprise Linux 5.1, and a 3rd VM running Openfiler 2.3. Each VM has a second virtual NIC connected to an isolated vswitch which functions as the RAC interconnect network.
    I've completed the configuration of the cluster and all the checks (as per the article) report that everything is a-OK.
    However I've noticed that there is a high rate of disk activity on my server, which continues constantly. I've left the server running overnight and the continuous disk activity is still there! :(
    I also noticed yesterday that I could not stop the first instance using either the instance specifc srvctl stop instance -d orcl -i orcl1
    or the global srvctl stop database -d orcl. In both cases the command appeared to hang. I had no problems stopping the second instance on the other node though. Not sure whether this is related.
    So - does anyone else run a similar "single box" setup, and if you do are you noticing similar constant disk activity? If not could you recommend any troublehooting steps I can take to determine the root cause? While the disk activity is contant, the "bursts" appear random, so it looks like something is going on. Not sure what though! :)
    Any replies would be much appreciated.
    Peter

  • [SOLVED] KDE Plasma doesn't load correctly sometimes

    Hi!
    I have strange problem, if i remember correctly since the last qt upgrade. Sometimes the plasma desktop just doesnt load fully, my desktop doesn't react on hotkeys, panels doesn't work on any click, superkaramba doesn't load. The only thing that works is the KDE menu, ant if I run an application from there, plasma starts to finish loading (superkaramba appeares, hotkeys start to work, so it finishes the initialization). It doesn't happen at every startup. This wasn't a too big problem, I thought it would be corrected with a new upgrade, but today my kde desktop froze. My computer didn't react to anything, sometimes  was able to move the cursor, but after a click, this only function also disappeared. I restarted my computer with the reset button, and I also had some strange things on my monitor at boot, and kdm didn't load correctly, I had only two input areas, with unrecognizable characters. So reset again, and I started windows (i have a dual-boot system), and it also had some stranges stripes at startup, and didn't load correctly. So I turned my computer off, and back again (so not with the reset button), and that time nothing strange happened at boot time, KDE started correctly, but I got a freeze again after some time.
    Has anybody had similar problems? Does anybody have an idea what could cause this? I'm not sure it's a software related problem, but it started like one.

    Even with the plugin disabled in chrome://plugins I still see the same ammount of IO.
    Any ideas why it's making so many writes?

    As long as you bought a decent SSD, I wouldn't worry about this too much.  In the early days, when the firmware was still you and it sucked, the wear levelling didn't work properly and disks would prematurely die.  But these days, with new disks, it has been found that the controller will likely die long before the flash wears out.
    I have a Samsung 840 250GiB, which as you may or may not know, is Triple Level Cell (TLC).  If you also know anything about SSD flash, the originals were Single Level Cell and the SLC these days can sometimes do 100,000 write cycles.  Multi-Level Cell (MLC) consumer disks are typically rated for 3000 to 5000 write cycles.  So as you can guess, this means my TLC is significnatly lower than the MLC.  But I have seen a couple tests with these 840s, where it was just constantly written to at a write amplification of 1 (you'll never actually see this low of a write amplification in real life), and it lasted for several months.  At that level, it was determined that under "normal use" it would last something like ~160 years.  Even with a rather high write amplification of 10, that would still be 16 years.  So don't worry about it.  Just use it.
    In any case, I also don't like how much chromium writes to the disk, but this would be the case whether I was using an SDD or an HDD.  So I use the /etc/chromium/default config to also add "--disk-cache-dir=/tmp".  This is also where those pappi switches can be found (the post_install function of the pappi package writes this for you).  That switch will make a directory /tmp/Cache, where chromium will store its cached web pages.  This would otherwise be in ~/.cache/chromium/Cache I believe.  Your normal profile, passwords, form info, bookmarks, etc. are all stored in ~/.config, so you don't be losing any of that.

  • In Lion, how would a user REPAIR disk without a disk to boot from?

    In Lion, how would a user REPAIR Disk without a disk to boot from?  It's cool to download Lion from App Store, but I think they need to solve how they will repair disk without optical disk to boot from.  I have had to repair disk in with the disk utility around 5-10 times in the past.

    Well it should be stupid, but people do it anyway not realizing it's importance later when something goes wrong.

    That does confuse the issue, a bootable DVD is for installing the operating system after a hard drive replacement, which also will include the recovery partition.
    Recovery parititions are a great idea for Windows as it fails often, but hard drives fail more often in Mac's than the operating system.

  • HT201250 My MacBook is slow.  I have a cleanup programme and I do not have many applications.  I would like to clean the disk and restore from Time Machine.  Will it still be slow?

    I am frustrated having paid for "Clean My Mac" which I run regularly and using tips like cleaning the cache in Terminal view.  It is still getting slower.  Can I clean off the disk and reinstall from my Time Machine, or will it re load the problem too?  How do I do this anyway?

    BS heißt "Bull___****". *lol* "Betriebssystem" heißt imemr noch "operating system". GoLive wirste wohl gar nicht zum laufen kriegen. ohnehin würde man es nicht mehr verwenden, weil es noch nicht mal CSS2 voll unterstützt geschweige denn HTML 5 und andere moderne Webstandards. Wenn überhaupt, dann findeste vielleicht noch 'ne OEM CD von Strato oder 1und1 bei eBay. Die haben das damals mit jedem neuen Hostingvertrag rausgehauen. Aber wie gesagt, es ist den Aufwand nicht wert. Illustrator sollte sich durchaus installieren lassen. Eventuell einfach nochmal die Installer im Win XP Kompatibilitätsmodus laufen lassen...

    Since you mention "commercial DVDs" I asume they use some kind of copy-protection.

  • HT4461 How to load a copy of Lion on to disk to boot from and install OS onto MacBook after replacing HD with SSD?

    Hello, All.
    I am replacing the Hard Drive (HD) in my MacBook with a Solid State Drive (SSD) to improve reliability and speed.  How do I go about getting the Lion OS, which only came as a web download, onto a disk to boot from and load onto the SSD?

  • I hear a lot of disk I/O from my iMac 1TB drive.  How can I see apps may be running in background?  Time Machine is not running.

    I hear a lot of disk I/O from my iMac 1TB drive.  How can I see apps may be running in background?  Time Machine is not running.

    If you wnat to see the applications that are running, open the Activity Monitor application (it's in /Applications/Utilities). After opening it, select "All Processes" above "Show" in the toolbar, and you will see all the processes that are running.
    I/O errors often happen on a damaged hard drive. If you are receiving that error, you should make a backup with Time Machine or Carbon Copy Cloner as soon as possible and take your Mac to an Apple Store or reseller to get another hard disk.
    If the warranty is void, you can try installing it yourself, but note that there are some iMacs which are very difficult to have the hard drive replaced. Search the steps in iFixit > http://www.ifixit.com
