Hardware :: Excessive CPU Usage With AMD SB750 Southbridge When Copying Files
Dec 3, 2010
I am using a 790FX chipset with SB750 southbridge and running Mandriva 2010.0. The sata controller is running in AHCI mode with several harddisks attached. The problem I am having is that everytime I copy files from harddisk to harddisk or harddisk to usb flash drive, CPU usage goes to 100%. Could there be a problem with the ahci driver in this kernel version, something related to disk cache, or something simple I am overlooking?

Just noticed from the "top" command that one of my least heavily used box is swapping excessivly by a program called setroubleshootd. Following is the top section of the "top" command sorted by Swap used for both boxes. Also tried checking it out to see if there's a "service setroubleshootd restart" but when I checked the status I got the following.
Code:

For some reason, if I leave my Linux box running for several days, the swap space and RAM slowly fill up until my system is so slow that it takes around 15 seconds just to open a new tab if Firefox (Iceweasel, specifically). I have 512GB RAM and almost a gig of swap; how on earth does it fill up so much? Even if I close all my programs, there's still over 600MB swap used and all RAM is full. I've included a screenshot of 'top' running just about two minutes after I closed all my running programs.
(Before I closed it, I had only 71MB swap free.) I know that Linux is supposed to make good usage of RAM, but isn't this over the top? Is there a way to force it to use only required memory with no or little extras kept in RAM? Just thought I'd add in the fact that I'm running Xfce as opposed to KDE or GNOME in an attempt to have a smoother running system on my old hardware. Also, what's the "VIRT" column?

I have run into a problem with my desktop using roughly 50% RAM (w/o buffers or cache) while running a limited set of applications (fbterm, tmux, weechat, ncmpc, rtorrent) on the command line. This usage only increases roughly 5-10% when starting X (an addition of xcompmgr, awesome wm, zim, parcellite, 2x conky (one replacing root-tails functionality), plus firefox and other apps that may or may not be running from time to time). (h)top is reporting programs only using roughly .1-.2% per proccess and roughly 100 processes (current look at top shows 120 processes, only 32 of which are registering any usage over 0.0%) The RAM usage when in the console (which I will add is about 150MB after boot) is totally unreasonable and I need some direction on trying to find out what is using all of this RAM.
System:
Distro: Arch Linux
RAM: 2G
CPU: AMD 64 x2 4800+
HDD: 3x WD Black 750G (RAID 5 on partition 2 (swap) and 3 (root), RAID 1 on partition 1 (boot). LVM over root partition)
GPU: Nvidia 8400 GS

I've discovered that Dolphin seems to lose random files when copying many large folders.
I first noticed this a few months ago when I tried to copy my music library from one folder to another on the same HDD. It consisted of around 600 folders and 6500 files. During the copy there were no errors but after the copy I found that some of the newly copied folders were missing files. I put it down to human error or a glitch.
Yesterday I tried to copy 13 folders containing rips of some of my DVDs. Each folder basically had one film of either 700MB or 1.4GB. Again no errors showed up during the copy but I found 3 of the newly copied folders were empty.
It's not so critical with music or films but I can't afford to lose work data like this.
Has anyone experienced or seen a similar problem with Dolphin? I'm going to have to do some more extensive testing but this is not good.
The first time I noticed the problem I was running KDE4.3.4 (I think) and now the latest was with KDE4.4.0.

The intention is to have this system dual-boot. When i first put it together, i decided to setup a raid5 array spanning 3 sata drives. I installed Windows 7 first, decided i'd get to Linux later. I left 150mb or so at the beginning of the array for /boot, and about 200gb at the end for my linux install. i'm getting to the linux install. My distro of choice is Fedora 12. I start the setup, and at the point where it's time to partition, the installer tells me that its unable to find any suitable storage devices.
I Crtl-Alt-F2 to a console, and fdisk -l. Fdisk reports three individual drives which all have partitions already. All have free space. None make sense. So i turned to google, and found some threads which explain that this chip doesn't run a true raid, rather its what's been referred to as fake raid. Which is that it depends on the windows driver in order to actually present the array to the OS, and that the best way to get by that on linux, is to break the array, and use LVM instead.
That's all well and good, but i lose two things in doing that. First i lose the resiliency of raid 5, and second, well, what does that do to my windows install? I've considered moving all of my data from windows to other machines, and then just starting from scratch, but i'd really much prefer a method of using the chips fake raid in linux. Is there a driver, or module which i can install to make this happen?

I installed a new dvd copy of fedora13, and now connected 2 USB hard drives that seem to connect fine, can access everything but if i try to copy files to one of the drives it says i don't have permissions, and the fields to change permissions access are blank.

My Source folder contains 424.8 GB in 502,474 files. My Destination folder was created fresh, and after the copy contains 394.0 GB in 486.514 files. I am running it as grsync with root authority. The only options are to preserve time, permissions, owner and group., and to produce a verose output and transfer progress. There are no exceptions specified to skip any files.
The rsync command is this:
rsync -r -t -p -o -g -v --progress -c -l -H -D -s /mnt/Backups/monthly.3/ /mnt/EX-Fantom/monthly.3/
I have run it again to give it a chance to get it right. Same result. The source is in an rsnapshot folder, but this is the first backup, the original, containing only whole files, not links.

I had to leave rather suddenly (decision was Germany's, not fiancee's), and now am in the States again, but my files are still there. There are lots of things (mainly photos) on there, that I would like to have here. SOME stuff is on CD/DVD, but there is stuff that isn't.
Is there some way that I could access her computer and just copy files to mine?
(I picture two folders, one on hers, one on mine, and I just dragging an icon from one to the other - but I don't suppose anything's THAT easy...)
Naturally, her computer would have to be on, and I assume she could not be using it herself. Naturally also, I would get her permission first...
I assume that it would take a while, but if it were as simple as the icon thing I described above, then I could just go away and come back later. I assume something would be running to make sure that the destination file and source file were identical before proceeding to the next file.
[Before you suggest: why doesn't she just copy the files to DVD's and mail them to me? She is not all that computer saavy, I'm afraid, and trying to explain it all, including the exact folder names and such, Plus, how to use a DVD/CD burner and software... Plus translate it all into German... If I were rich enough, I could just go there and do what I needed, but that is not in the cards for the present. ]
IS there a way to copy stuff from her computer to mine?

I have a new network attached storage unit that I'm trying to transfer my data to. On this NAS, it has a very basic linux installed with SSH enabled. Browsing through the programs installed on it, i found smbclient. Am I able to copy files directly from my old NAS to my new one using smbclient?It would sure beat transfering 950GB from my old NAS through a computer then onto my new NAS.

While copying a large amount of data between two linux computers I noticed strange behaviour. The network card activity (computer copying the files) would be dormant for 30 second to a minute and then flash rapidly for just 5 second or so. This repeated for the duration of the copying progress (approx 2 hours at a supposedly constant 5-7MB/s).
The share that I was copying to was via SSH using "connect to server" from the GNOME menu. I was expecting the see the network card activity light constantly flash. I wondered if someone could explain this strange behaviour that I have witnessed.

I'm running squeeze on i686, my last update was this morning (9/9/2010). Running the stock kernel 2.6.32-5-686
My PC keeps crashing when copying files. The monitor displays the desktop, but the mouse doesn't move, nothing responds and I can't even ssh in to debug it.
This happens when copying files using nautilus and the command line. I'm trying to copy files from my local hard disk to an nfs drive which is mounted in my system and has been working fine for years.
how to debug this after a hard reboot?
This has only just started happening, last night was the first time.

During my backups I'm finding that rsync is copying all files, instead of just what's changed.
I'm rsyncing between 2 USB external hard drives. One hard drive is FAT32 and one is NTFS. I've examined some of the files and believe that the difference is that there's a 1-second modtime difference developing in some of the files somehow.
Here's an example. These duplicity files were synced from /media/BACKUPHD (the NTFS drive) to /media/VIDEOHD (the FAT32 drive) only a few hours ago this morning. They have not been touched or changed since then, but that 1-second difference in their time stamps has appeared:
Code:
tim@localhost:~> stat /media/BACKUPHD/backups/duplicity/duplicity-full.20110107T145955Z.vol10.difftar.gpg File: `/media/BACKUPHD/backups/duplicity/duplicity-full.20110107T145955Z.vol10.difftar.gpg'

I just read the Linux scp command issue question and it reminded me that I regularily forget to specify the colon in the host part of a scp command, and thus copying a file locally instead of copying to a remote host, e.g. I do
scp foo host
instead of
scp foo host:
But I never use scp to copy a file locally. So I wonder if there is a way to make scp fail if both (the source and destination) arguments refer to local files.

I need to copy ~300GB of drives from one Windows hard drive to another using a Ubuntu live CD. (I currently don't have enough power connectors for my Windows system drive AND both existing and new data drives. Stupid power supply.)
By Windows drive, I mean the drives are only data drive (no Windows install) but the files on the first drive were created and are used by my Windows system, both were formatted NTFS in Windows, and the files will again be used by Windows on the second drive.
Are there any pitfalls I need to be aware of, or can I literally just drag the files across in Nautilus? Is there a faster copy utility available (I know there are Windows programs that can copy faster than drag-n-drop, but I'm sure Ubu doesn't have the same problem ) Will using a Live CD cause any specific issues?
