I've just completed a fresh install on natty, and I'm seeing constant disk writes of around 1Mb every couple of seconds.
I looked at iotop to find the culprit, and it seems to be the journalling manager for the ext4 filesystems:
Code:
215 be/3 root 0.00 B/s 19.23 K/s 0.00 % 5.89 % [jbd2/sda1-8]
Is there something I can do to adjust this behaviour somehow? I'm a bit concerned about wearing the disk out before its time...
System:
Ubuntu 9.10
Gateway SX2802 (Core 2 Quad)
4GB RAM
750GB drive
Everything was fine for the first 6 months. Now in the past couple weeks, my disk drive is running nearly constantly. I can hear it rattling away in the background no matter what I am doing. Typically, I just have Firefox open, and that disk drive is sounding like it's writing the whole thing over and over.
I've opened the system monitor and looked for something obvious, but everything says, "sleeping". The computer seems to operate fine - no crashes, no odd behavior. What's this thing doing?
This is a curiosity of mine, and I expect a technical answer, if someone knows it. Why the systems become so irresponsive when doing hard-disk input and output? This happens even if writing is done to a secondary disk where neither the system or the swap are stored.

It frozen up occasionally, when that happens, usually the harddisk light lights up continuously. So I suspect some process is writing to the disk, which prevent other process to go on. how do I find out who's using a lot of IO?
View 3 Replies View RelatedI'm writing a script that among other things partitions and formats disks using SW RAID and LVM. I've read somewhere that for older versions of Linux it was a good idea to use the dd command to zero the first couple of blocks od a device before partitioning it (or formatting it?) Is this practice still recommended? To what end?
View 1 Replies View RelatedI've got a few linux boxes (fedora 13 and 11) with a common disk mounted. I'm trying to get them all to write files to that disk, however it seems that only the first to connect actually has permission to write.
I'm very new to this networking stuff and this is a bit of a hack. Is there anyway to give all computers write access to a disk (it's actually a managed back up disk, primarily for windows users but is the only shared disk in the building), or is this likely to be very very complicated?
Whenever I am busy reading or writing large files, or large sum of files, my computer is unresponsive. Screens are getting greyed-out and I just can sit there and wait until the reading/writing is done.
This is not caused by the CPU which is overstressed because it is not. Look at the attachments and you will see the CPU is used for about 20%. When these pictures were captured the computer was using hellanzb to unrar a long list of rar-files.
When you look at my signature you see the computer is not bad at all, just disk-access is slow. I can transfer files with a maximum speed of 30MB/s. Is that normal or is it very slow? I don't know the numbers. I have 2 SATA disks.
O.S. is Mint 9-Isadora, based on Ubuntu 10.04 and I use the 64-bits version.
I've got a Centos 5 machine running with a raid 1 SSD hard drive combo, as I don't know how or even if it's possible yet to wipe the free disk space clean I need to be careful to not fill all the free disk space. As I don't want to fill the free disk space too quickly and was wandering if it is possible to pipe the result of a mysqldump to a FTP client only writing it to the ram and not writing it to this disk.
I've done a bit of research on the subject and have found the two following commands:
Code: mysqldump < mysqldump options> | gzip > outputfile.sql.gz
Code: tar cf - / | ncftpput -c sonic.sega.co.jp /usr/local/backup.tar
I would like to combine the two to make something like this:
Code: mysqldump mysqldump_options > | ncftpput ncftpput_options -c SERVER_IP backup.sql
I haven't actually tried my code as it seems too easy and I'm sure I've got something wrong! If this command is even correct will it prevent the sql file from being written to the hard drive to my local machine?
For internal security reasons I need to prevent ourmcat logs from writing to the webserver local disk. We set up a separate logging server with rsyslog and need to pipe the log data to it.I am trying to work out how to configure tomcat to send all log data to the logging server via the rsyslog client (running locally) via a named pipe. We are on CentOS 5.6, Tomcat 6 and rsyslog 5.8.1. I need to know: 1) do we use the default logging library or log4j2) where is this configured in the tomcat config3) is there any code that would need to be written to achieve this
View 1 Replies View RelatedI've managed to install the 32bit version on my laptop with little issue, and I'm really liking the Unity interface. There's a few issues around customisation and minor usability quirks, but from my experience with things like KDE4, I'm guessing it's only time. Anyway, I've been having major problems getting the 64bit version running with my Desktop. I have 8Gb of RAM in that, so it's not really an option to use the 32bit version. The Installer crashes constantly, but I was able to upgrade from 10.10 using update manager, but unfortunately Natty is no more stable than it's installer.
While logging in, or shortly after, the machine will crash to a text console displaying a Kernel Panic message. There's also messages indicating a problem with the CPU MCE. I've tried setting various kernel parameters at boot, such as nomce and nomodeset, these have extended the time the machine is up before crashing out, and removed the Kernel panic message, but not the crashes. I'm guessing the MCE messages were unrelated or a symptom in this case.I've done a huge amount of searching, and found no suggestions that I haven't already tried. Running Ubuntu 10.10 64 bit the system is rock solid.
I think I have found the problem to my Ubuntu laptop locking up, and it is most likely overheating. Is there any way to keep the CPU fan spinning at 100% constantly? I tried setting it up in the BIOS but it is an old laptop and I can't control it from there.

Lasdt night I was busy installing WinXP when my computer suddenly turned off, and Ubuntu could not be started again. Only show a screen with black and white parts and no desktop.

I have also filed a bug about the same some 6-7 months month ago, but the ubuntu community seems busy with many other things.

My disks are constantly being remounted as read only. Even after I manually mount them and explicitly specify the rw option, after a while I find they have become read only. Needless to say, working like that is impossible. Fortunately the root partition is not affected, but every other partition is.
View 7 Replies View RelatedWe've had a very big problem with our computer chrashing for a while, and I'm not sure if it's Linux Ubuntu that's the problem or not be we'd like some feedback from the experts of this forum. I hope I'm posting this in the right place. So, a while back we had Windows XP on our machine, and it had been running well (as well as XP is capable anyway, ), but for some reason it wouldn't boot XP properly and would only allow us to open it in Safe Mode.
We opened up the computer to take the memory chips out and back in, just in case that would help, and the inside was terribly dusty. Also, we have a loose heatsink, and the chip underneath is filled with dust. Not sure what the chip is I'll try to get some picture of it pretty soon. Anyway, the inside of the machine obviously wasn't too good.
So, we installed Linux Ubuntu LTS 10.04 on it from a CD to try to fix the booting problem, and this worked -- but now, our computer crashes constantly after turning on. It crashes whatever we're doing -- we can do something light, like Google Chrome, or something heavy, like video editing, and have it crash on us. So it doesn't seem to be a problem with the programs or anything -- I'm guessing it's either an issue with the computer itself or an error with the operating system. Sometimes we're lucky and can be on the computer for half-hour to and hour and a half, but it's still really bothersome, and will get in the way of any projects that require saving or recording. I'd guess it crashes around 10-20 times a day.
I included a video of it crashing and what it does just in case that could be of any help. Link: [URL]... The screen goes blank for a moment -- shows oddly colored, fragmented bars in the center of the screen (sometimes red, sometimes silver), shows this text:

All of my windows disappear for about a second, leaving only the desktop wallpaper showing, then reappear.
