Software :: Intense Disk Activity At Login FreeBSD 8.1
Nov 12, 2010
For 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 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?
I 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
I'm running Ubuntu 10.10 on an Acer Aspire 5530G. On a fresh install, the HDD is silent after logging in and the desktop is immediately ready for use. A few days and updates later, after every login, there's heavy HDD activity that lasts about 20/30 seconds and makes it almost impossible to perform any other task. The entire desktop is visible during said event.
Not a big issue, however it bothers me a little. I've observed this behavior since Ubuntu 9.10. Anyone else experiencing similar problem?
I 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
I 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.
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?
I 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.
I just started messing with the networking tools in Linux, and I've discovered that when I run an intense scan in zenmap on 192.168.1.1-254, the network crashes. By network crash I mean - All clients on the network lose connectivity.
Just the last day or so, I've noticed a long pause when I boot my laptop, with lots of disk activity. dmesg says:
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?

before debian started using grub2 it was very easy to specify a loader from another partition but since grub2 came out it's a lot more complicated, you can no longer edit a text document menu.list, is there an easy way to edit the grub2 boot-loader to boot FreeBSD operating system since it doesn't recognize it from update-grub
Just a quick question as I re-familiarize myself with apt-get again. So far, have had no luck finding what I am trying to do (back to the man page) Basically, after doing a 'apt-get update' command, was it possible to see what packages have newer versions and can be upgraded?
For example, I am working with a system that has BASE 1.4.3 installed, and I know there is a newer version out (1.4.4), but want to make sure that is in the repository. Does apt-get have something similar to portmaster in FreeBSD? Where it tells you what version you have installed, and what version is available to download?
This is a humbling experience for a long time MS admin/tech.I am wanting to build a file server fr my home network. So, I downloaded and installed FreeBSD 8.1 last night.Wanting a more familiar interface, I downloaded and tried to install KDE. It loads and asks for language. Then I select "Install kubuntu".
The kubuntu logo and a progress meter pop up for a while. Eventually the screen goes black and nothing else happens. I have to reboot. If I take the CD out it boots to FreeBSD.Am I missing something? Kubuntu never asks anything regarding partitioning. Is FreeBSD an os like DOS and kubuntu a GUI like Win 3.1 or is kubuntu more like XP with a GUI built in to the os? If it is the latter, how do I get it to kill the FreeBSD install?"Try kubuntu without installing" does the same thing.
wanted to try out FreeBSD but I want to boot it from an ISO. I put my iso file on my first hd 3rd partition in /boot/iso/FreeBSD-8.1-RELEASE-amd64-dvd1.iso. But I can't seem find anything to boot freebsd this way. Is it possible and if so how. This is what I kinda got but its not working.
i have recently installed freebsd 8.0 after using ubuntu for about a year and a half. I have installed X11 and have tried to configure it as best as i can. when i run startx i just get a black and green screen.i configured the Monitor and Screen section of my xorg.config file as follows
Its my third week struggling to install mrtg on freebsd 8.0. I will be happy if someone can provide me with a HOW TO documentation on the issue. i would like to monitor my routers(bandwidth utilisation).
I had 40 gb of unused space at the beginning of my drive, then a 15gb primary ext3 partition for /, then a 100GB ext4 primary partition for /home, then a 4 gb extended partition that contains two 2 gb swap partitions.
I installed FreeBSD on the empty space at the beginning of the drive. The slice I created did not start on the first block. There were a few MB of free space before and after it.
After the installation finished (with no errors), grub would hang on the "Grub loading/Welcome to Grub screen". I booted a squeeze CD in rescue mode and reinstalled grub to /dev/sda. After rebooting, Grub still hangs at the same place.
I booted a live CD and checked the output of fdisk. For each of my partitions, it says "Partition does not end on cylinder boundary". I am hoping that whatever happened to my disk is not recoverable. Fortunately, I backed up some essential files beforehand, but I still don't really want to lose my old squeeze system.
Sometime in the next few weeks the office I just started working in wants me to switch their file server over to Ubuntu, from FreeBSD. I am a little scared of doing this, seeing as how I came into this job with no documentation of the network/hardware that I will be primarily working with. Does anyone have any useful tips/links that would be relevant to my task? So far, I have copied over the following files from the FreeBSD server:
Earlier today, I tried to install FreeBSD. If anyone here has done this, I think I went wrong at the part where it asked if I wanted to edit the Master Boot Record. In any case, now when I turn the computer on, it boots into FreeBSD instead of into GRUB. Now I have no access to Ubuntu or Windows, and I have no internet on FreeBSD. How can I fix the MBR so that it boots into GRUB instead of FreeBSD? I want my Ubuntu back...
