Ubuntu :: 10.10 - What Process Start Thrashing HD
Nov 20, 2010
ubuntu 10.10 At times something starts thrashing the HD. Often after the computer has been taken out of Suspension. The whole things slows down and stays slow. This can be fixed by logging off (which takes quite a while under this condition while the HD light stays on, solid) and logging back on. Then the system becomes responsive, with only HD light flickers. Anyway, I can't determine what process is doing the thrashing. System Monitor doesn't show any memory problems, and neither do top or htop. htop shows plenty of swap space available, and memory usage is on par with what it looks like when there is no thrashing. Is there some tool that can display what processes are running the HD so hard?

I'm trying to find how to schedule a process to start at a specific time (not on start up). How would I schedule a process/application to start at a specific time (if it matters, it will be a background process). For instance, have process abc start every weekday at 5am. I've done this for windows many times though have only been using linux regularly for a few months and haven't figured out the best way of doing this.
So far the best solution I have is to create a program that will start on boot and have it check the time and sleep until the required time and then start the required process(es) at the required time(s). But this seems more of a hack since I'd expect there to be a proper way of doing this.

Recently I have found myself getting terrible disk thrashing, to the point that my desktop is almost uncontrollable. I have found that killing the plug-in container task (I'm using 64-bit Firefox 4) brings the thrashing to an end. In other words it's a problem to do with Flash.

My ADSL router NAT's any computer behind it here at home. I have a PC or two a Sun ultra10 and ultra5 and E450 etc.
The problem is my PC reports via "tcpdump -i eth0" that
22:54:47.035683 IP icute.pelnet.net.50683 > 224.0.0.56.46144: UDP, length 1292
is going on 140 times every second.
How do I prevent this from continuing and why is it happening? If possible I don't want to invoke iptables as my NAT router does a fine firewall job.

I am running 64bit 10.10. For the last fortnight system has become very sluggish responding to input. Programs greyout and become completely unresponsive for long periods of time and cpu usage on one or both cores ramps up. As I type it is c.80% on both. System Monitor shows usage on the cores mirroring one another. top in terminal shows Xorg at 99%. I have attached a screenshot. I have rolled back and/or reloaded the Nvidia graphics drivers to no effect.

I have just build a new computer, and I want to install Ubuntu 10.10 on it. The problem is that when I run the Live cd and start the installation it cant find enough space to install. I have a 1TB WD Black Caviar disc installed and I can see that the BIOS detects it.

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.

Acer Travelmate laptop, 1.3GHz Pentium M, 12MB Ram.pensuse 11.4 (upgraded from 11.3)Vanilla install, not running anything special, always startup and shutdown from scratch, never sleepFor several minutes after KDE appears and I open an app (any app, e.g. Chrome) the hard disk is going nuts. WTF is it doing and how do I stop it? Also some programs take years to start, e.g. digicam took TEN minutes the other day even after waiting a while after booting, the disk thrashing the whole time. But in 11.3 it started almost instantly.

I'm dual booting Ubuntu 9.04 and 10.04 on an ASUS P5VD2-MX SE mobo with 3 hard drives, a couple of DVD writers and a multi memory card reader (USB).
The hard drives are:-
1 250Gb SATA MAXTOR STM325082
1 80Gb PATA HITACHI IC35L090AVV207-0
1 80Gb PATA MAXTOR 6Y080P0
9.04 lives on 2 ext3 partitions of the 250G SATA
10.04 on the 2 ext4 partitions of the 80G MAXTOR
The HITATCHI has 1 ext4 partition mounted as a common data area for each O/S
The 250G drive has GRUB Legacy in the MBR with its files in a small ext3 primary partition chainloading the 2 O/S's, GRUB Legacy for 9.04 and GRUB2 for 10.04. It also contains the common SWAP partition (primary)
When I boot into 9.04 everything works as expected with as far as I can see no unusual disk activity even when the ext4 data partition and the 2 10.04 ext4 partitions are mounted. When 10.04 is booted however, after about 5 minutes (irrespective of whether or not the other partitions are mounted) I see the hard drive activity light come on and stay permanently on. The system monitor shows nothing unusual. dstat doesn't give any clues either. I've tried running iotop but it fails with a missing CONFIG_TASK_DELAY_ACCT error.
Is this a known problem with ext4, should I rebuild 10.04 onto ext3 partitions? Are there some special ext4 mount parameters I should use? (I simply copied the fstab lines from 9.04 and just changed ext3 to ext4). I've read that the journaling process(es?) for ext4 by default commonly access the drive(s) every 2-3 secs but that should just cause a flicker surely.

I forced a quick restart with 'sudo shutdown -f now' and when logged back in gnome-panel doesn't start at all. I can right-click on the desktop & run terminal from there, so I'm running web browser from terminal. I tried 'sudo killall gnome-panel' & got 'no process found' I tried doing a full restart, still the same.
I tried running gnome-panel from the terminal.
'gnome-panel' gives me my panel after a 4 or 5 second delay. If I exit the terminal or Ctrl-C I lose the panel again.
'sudo gnome-panel' gives me what appears to be the panel for the root user.

Just loaded Squeeze (KDE) onto a partition on my desktop and am a bit alarmed by the disk thrashing thats going on? Damn light on constantly. if I didn't know better I'd think I was using Vista. Is this something to do with 'nepomukservices' that seems to be taking a fair amount of cpu time? Not used to KDE 4 so maybe this is normal.

I'm using the rhythmbox installation that ships with fedora for my music playback. Every time is start the darn thing up though I can hear my external disk (media library) being accessed really hard. I assume this is part of some sort of library self check and probably a check for new music(?). So this got me wondering on how rhythmbox keeps up with my media library and if there is a way to make it more! I assume that atm rhythmbox just checks every file it now in my library for 'something' and at that also checks for new files and folders in the library directory. So I guess It would be quite a boost in startup performance (disk thrashing) to just skip the existing files checks. Right? Well, I obviously don't know how rhythmbox ticks so be nice.

I've noticed tracker-store burning CPU and thrashing disk when I login to a KDE session. I'm tempted to disable it by modifying /etc/xdg/autostart/tracker-store.desktop. But before I do that, what added value does it bring to the party? It seems like it's mainly involved with desktop indexing, which I never use (does anyone?).

I've just installed subversion.I need to create a script /etc/init.d/svnserve that will start at boot time.I want to use start-stop-daemon --start so I can track my process and eventually kill it using start-stop-daemon --stop.My problem is that I can't get it to work and the documentation shows no exemple.
I've replaced $DAEMON by the whole line: svnserve -d -R -r $REPO_ROOT and got -d is not an option.I'm not quite sure what to do at that point. If someone has some experience with start-stop-daemon it would be great.

I downloaded Ubuntu 10.10 and made created a DVD. When I started installing it, I'm not able to do it. I think its hanging. This is what happening: First I found a screen saying 'ubuntu 10.10' and it loaded for some time then I got a screen with a black color task bar at the top of the screen, then after some time it turned into white color and after some time it disappeared. Nothing else happened. I didn't find any pop-up window to start installation of OS..
But when I tried this in my friends house, I found that instead of 'ubuntu 10.10' there came 'Ubuntu' LOGO and it was little bit slow but a pop-up window opened to start installation..
Why its not coming in my PC..
my computer configuration :
Windows XP, SP 2
256 MB RAM, 1.81 Ghz
AMD 64 Athlon Processor 1800+
I want to shift my OS to Ubuntu completely.

I have a ubuntu 11.04 LAMP server at home.
Its runnign a few small sites on a drupal CMS.
This morning I found none of the sites were responding. The server itself sounded like it was thrashing the hard drive.
It wasnt responding to the FTP client or SSH connections. Web pages just sat there like they were loading very slowly but never actually loaded.
How can I find out what went wrong. I dont have a massive amount of experience with linux, particularly the server variant.
Its worried me a little that the drupal report shows several page not found errors like someone (a bot maybe) was trying to see what php setup files they could access.

I had been having problems with every LiveCD after 8.04.1 I tried both xubuntu and ubuntu (same internals, same results)
I ended up installing xubuntu 10.4 using the text mode installer.
The system basically works, I can not get gdm running.
dbus fails as noted above. I found launchpad bug #446971 and tried some of the work arounds with no success.
The system is an old eMachines T1120
Code:
CPU: Intel Celeron Processor 1.20GHz (w/256KB)
Operating System: Genuine Microsoft Windows XP Home Edition
Chipset: Intel 810e chipset

So, I am looking to implement an FTP server with Isolated Client accounts/directories where a client can only access what's in their directory. I also need to provide my internal user's (content managers) the ability to upload, delete, etc from all of the Client accounts. The simple part is creating the secure client accounts. It's a matter of changing DIR_MODE in adduser.conf to 700 or 770, creating a user, having the FTP server chroot them to their home directory, revoke/restrict shell/ssh access and maybe even slap on some ACL to prevent botched permissions.The hard part is figuring out how to give my power users the ability to access all of their folders without thrashing security.
My first thought was to put all of the client user-groups in a parent group and having my internal users inherit group permissions..but you can't have groups inside of groups.My second thought was to put all of the client users in the same group and prey that the FTP chroot is enough to keep them from poking around but then I have the problem of how do my internal users access other user directories if they are chrooted. Do I create a second server without chroot.do I create some weird nested homedir structure..I honestly have no idea how to satisfy both requirements (secure client accounts and privileged user accounts). I need my privileged users to authenticate against Active Directory via Likewise open, LDAP, etc and I don't care how the clients authenticate. Though, I would prefer to have both file and FTP-server level protection just to make sure no one can see the other client's data.

We are having a Linux box with Tcpdump continuously running on it to monitor bunch of sources. Separate Tcpdump process runs in a background for each host for monitoring traffic. I use -w option with it to save the capture in the pcap format to analyze it later. Now what I need is, if the Linux machine gets rebooted amidst of its packet capturing activity, I want tcpdump to automatically start the process again for every host without overwriting previous captures.
Remember: Without overwriting previous captures . . .
Basically, I will be keeping all the tcpdump commands in the shell script and will load the script at startup during the linux boot. Is there any way to achieve this case, where by on rebooting, Tcpdump does not overwrite previous captures?

I need help adding a nohup command in this command line: su - rhx12 -c "/rhythx/rhythx/bin start /rhythx/rhyth" When I execute the script using root on the command line it works fine. But, when I reboot the server the process doesn't start. This script will go into the etc/init.d and rc2.d directory.

this is not specifically a slackware related question, but since done on 2 slackware boxes... the situation is, i have one box for browsing and other desktop activities and another box acting as router/local server. what i want to achieve is that the router box would look on a nfs mounted folder for new *.torrent files (which i put there from the desktop box) and if there is a new file, it would start downloading it automatically. also a good thing would be if it would notify me when finished.so how would you go about itwhat torrent client would you use and so on? maybe someone has already done something like this?
