  • win 7 something is causing excessive disk usage, maybe chrome?

    - by camcam
    On my Win 7 computer, this happens: I work for several hours without problems, also using Chrome Suddenly, just after refreshing a page in Chrome, disk starts being used excessively (here I can close Chrome or not, no matter, the disk won't stop) Disk diod is on all the time and I hear it running like crazy, all computer is a little slowed down It last 5-10 minutes In the meantime, I go to Windows Task Manager and observe what processes are using disk and turn them off one by one - but no success in stopping the excessive disk usage After approximately 10 minutes everything stops I go to Chrome (or re-open it) and refresh the page with mixed results - sometimes the whole process repeats immediately, sometimes not Basically, it is almost always Chrome refreshing random page that starts the excessive disk usage, but killing Chrome process does not stop the disk. Going to the same page in Firefox is not causing problems. Windows Search is turned off. I would like to know what is really happening. Perhaps there is a utility which would allow me to see which process is really using the disk, so that I can disable the service ? (not chrome, because killing chrome does not change anything) or even better, perhaps there is a way to fix it?

  • Application that will identify percentage of your system disk bandwidth used on a user-application by user-application basis?

    - by Warren P
    I always (subjectively) feel my computer is far too slow (however fast it is), and so I'm always looking for ways to measure and understand what my computer is actually doing, that is making it seem "slow" to me. It has been my observation that my software-developer workload is most often disk-bound (I am waiting for Disk I/O) more than CPU bound. What has made it worse, is that I am using a corporate PC that has in-memory active-scanning anti-virus software that I do not have control over, and also some IT department mandated services that seem to suck up a lot of available hard-disk bandwidth. The best tool I have seen (in Windows 7) is the Resource Monitor which I usually acess from the button in the task Manager. The disk IO page, however, seems to label Disk Activity at a very low level (for example, showing the Volume Shadow Storage, which is flushing information obviously written by something ELSE other than VSS itself, and then writes to Pagefile.sys, which are obviously due to Virtual Memory faults in some application). What I would like to know is if a utility exists that can add up all direct disk input and output by user-level process, or find the process or service that caused VM or VSS activity. In that way, I hope, you could establish a real idea of how much of your computer's precious disk subsystem bandwidth is attributable to a particular application. here's a scenario: MyApp.exe writes 100k/s and reads 100k/s directly. VSS ends up writing another 100k/s. pagefaults caused inside MyApp.exe cause another 100k/s of writes. So the total "cost" of MyApp.exe running, during a period of time (let's say 1 second) is 400k/s, whereas you can only directly observe half of that, in Resource Monitor. Is there a smarter disk-IO watching piece of software I can use?

  • Update to SQL Server Configuration Scripting Utility

    - by Bill Graziano
    Last spring I released a utility to script SQL Server configuration information on CodePlex.  I’ve been making small changes in this application as my needs have changed.  The application is a .NET 2.0 console application.  This utility serves two needs for me.  First it helps with disaster recovery.  All server level objects (logins, jobs, linked servers, audits) are scripted to a single file per object type.  This enables the scripts to be easily run against a DR server.  If these are checked into source control you can view the history of the script and find out what changed and when. The second goal is to capture what changed inside a database.  Objects inside a database (tables, stored procedures, views, etc.) are each scripted to their own file.  This makes it easier to track the changes to an object over time.  This does include permissions and role membership so you can capture security changes.  My assumption is that a database backup is the primary method of disaster recovery for databases so this utility is designed to capture changes to objects.  You can find the full list of changes from the original on the Downloads page on CodePlex.

  • Utility to Script SQL Server Configuration

    - by Bill Graziano
    I wrote a small utility to script some key SQL Server configuration information. I had two goals for this utility: Assist with disaster recovery preparation Identify configuration changes I’ve released the application as open source through CodePlex. You can download it from CodePlex at the Script SQL Server Configuration project page. The application is a .NET 2.0 console application that uses SMO. It writes its output to a directory that you specify.  Disaster Planning ScriptSqlConfig generates scripts for logins, jobs and linked servers.  It writes the properties and configuration from the instance to text files. The scripts are designed so they can be run against a DR server in the case of a disaster. The properties and configuration will need to be manually compared. Each job is scripted to its own file. Each linked server is scripted to its own file. The linked servers don’t include the password if you use a SQL Server account to connect to the linked server. You’ll need to store those somewhere secure. All the logins are scripted to a single file. This file includes windows logins, SQL Server logins and any server role membership.  The SQL Server logins are scripted with the correct SID and hashed passwords. This means that when you create the login it will automatically match up to the users in the database and have the correct password. This is the only script that I programmatically generate rather than using SMO. The SQL Server configuration and properties are scripted to text files. These will need to be manually reviewed in the event of a disaster. Or you could DIFF them with the configuration on the new server. Configuration Changes These scripts and files are all designed to be checked into a version control system.  The scripts themselves don’t include any date specific information. In my environments I run this every night and check in the changes. I call the application once for each server and script each server to its own directory.  The process will delete any existing files before writing new ones. This solved the problem I had where the scripts for deleted jobs and linked servers would continue to show up.  To see any changes I just need to query the version control system to show many any changes to the files. Database Scripting Utilities that script database objects are plentiful.  CodePlex has at least a dozen of them including one I wrote years ago. The code is so easy to write it’s hard not to include that functionality. This functionality wasn’t high on my list because it’s included in a database backup.  Unless you specify the /nodb option, the utility will script out many user database objects. It will script one object per file. It will script tables, stored procedures, user-defined data types, views, triggers, table types and user-defined functions. I know there are more I need to add but haven’t gotten around it yet. If there’s something you need, please log an issue and get it added. Since it scripts one object per file these really aren’t appropriate to recreate an empty database. They are really good for checking into source control every night and then seeing what changed. I know everyone tells me all their database objects are in source control but a little extra insurance never hurts. Conclusion I hope this utility will help a few of you out there. My goal is to have it script all server objects that aren’t contained in user databases. This should help with configuration changes and especially disaster recovery.

  • What does 'Highest active time' for disk activity in Windows resource monitor mean?

    - by Nick R
    I know what the disk io, disk queue length and other measures are, but what does 'Highest active time' mean? Is it the amount of time it is busy handling requests, or something else? When it is high, does it mean the CPU is busy doing some IO work, or is it just indicating that the disk is busy handling requests? I'm trying to work out if 50% active time means that 50% of the time the disk is either seeking, reading or writing, rather than the kernel is spending 50% of it's time servicing IO requests. Edit Another quick data point here. If you look at the difference between an SSD and a physical disk, the SSD has significantly less activity, so I guess this really means the amount of time the operating system is waiting for the disk to respond and returning data.

  • Disk is spinning down each minute, unable to disable it

  • Windows 7 Reading Proper Disk Usage Statistics on Mounted Volumes

    - by Troy Perkins
    I'm running windows 7 with 2 x 1.5 TBYTE Drives. The second internal drive is setup as a mounted volume as C:\Archives Clicking computer icon in windows explorer, it only shows capacity stats for C: and Not C:\Archives Also, the usage stats that do show for C: show to be 100% capacity red - yet the system runs fine. No warnings. Can someone explain this? I do have a lot of stuff on the c: drive, but I'm sure its not 1.5 TB worth and C:\Archives hardly has anything it. Thanks! Troy

  • Windows 7 disk backup and clone for deployment to multiple systems

    - by gregmac
    I'm in the process of deploying some new PCs (there's only 8), all identical hardware. What I'd like to do is install Windows 7 (64bit), join to domain etc, install a bunch of other software, and then clone that drive to multiple other machines. I'd also like to be able to use it as a backup image, so the machine can be restored back to that image at some future date. I understand this involves at least sysprep, but I am confused after reading some tutorials that talk about using Windows Automated Installation Kit, or hacks with the registry and custom-build batch files. This process seems overly complex to me: I did something similar 10+ years ago, and and don't remember it being this bad. Surely things have improved in a decade? There's also some products that involve having network servers running deployment software, network boot, etc etc.. this is way more than I want to set up. My systems are all identical hardware. Is there a simplified way to clone PCs? Preferably (since I'm a lazy developer, and not an IT admin) I'd like to find some off-the-shelf product that I can run after I get the machine setup, that will spit out a bootable DVD I can run on all the other systems, which will boot up, ask for a computer name, join it to the domain, and that's it. Does such as product exist?

  • Windows 2003 Dynamic Disk error

    - by ChrisH
    Hi, I was trying to ghost a partition on a Windows 2003 server, using Ghost 2003. Unfortunately things went horribly wrong, and now I can't boot back into my system. As you can see, Ghost creates a wee little partition to do its dirty work, and has dislodged my other partitions. Partition 2 in the image below is my C drive. Any suggestions as to how I might get this active again so that it boots? Cheers, Chris

  • Idle hard disk makes noise.

    - by ULTRA_POROV
    Like a fan or something. I checked it. I stopped all fans (cpu, video, psu) and the noise was still there. I read online that it might be a motor or something. I have put a great deal of effort making my pc quiet. Installed a quiet psu and cpu fan, reduced the fan speed of my video card, bought a ssd... But my drive for data makes this noise. I would never have expected that. Do all hard disks make this kind of noise? I guess most people won't notice it because of the other fans they have in the system, I however can hear it quite clearly because all my other fans are almost silent. So should i get a new one or should i just live with it, considering that i might end up with a drive that also makes this noise.

  • vista winsxs folder eats disk space

    - by Simpzon
    My machine has been running Vista Ultimate 64-Bit for about two years now. ServicePacks SP1 and SP2 are installed, too. The system partition has a size of 55 GB, which should be quite comfortable under normal circumstances, but about 40GB (no typo) are used by the Windows-Folder, especially the subfolder winsxs, which takes about 35 GB. I have already uninstalled as many programs as possible and did run compcln.exe, to reduce it, but this only gained 2-3 GB. What can I do to clean up without risking system stability? I'm a software developer and this is my daily work environment, which means - I can't risk to get strange side-effects from blindly deleting stuff. - You can maybe deduce some typical usage patterns from this information. Any suggestions?

  • Tracking down rogue disk usage

  • how to limit disk space per user in a PHP web application & CentOS

    - by solid
    we have a web application written in PHP and we want all our users to be able to upload images for e.g. 50MB. We will create a directory structure so that every user has its own folder like app/user1/images app/user2/images ... Now everytime a user uploads an image, we need to check if this is still allowed or not but we don't want 1000 users to continously scan our hard drive counting file sizes in their directory. So writing a script that counts all file sizes in a user directory is not an option I guess? Is there an easier way to calculate used up space per user and limit our app accordingly?

  • Save Website To Disk

    - by Christian
    Hello everyone! I have a very poor internet connection when I'm living at home. The only time I have a good internet is at college. When I get home, the most mundane task like opening a web-page becomes a five minute stress-test. So what I was thinking was to download the web-page, for example superdickery. I was wondering what the best method would be to download the entire image archive of the page? Would this be illegal, if I did this? It's just that I don't want to be frustrated every time I just want to load a simple jpeg image.

  • Server nearly unusable when doing disk writes

    - by Wikser
    My question closely relates to my last question here on serverfault. I was copying about 5GB from a 10 year old desktop computer to the server. The copy was done in Windows Explorer. In this situation I would assume the server to be bored by the dataflow. But as usual with this server, it really slowed down. At least I could work with the remote session, even there was some serious latency. The copy took its time (20min?). In this time I went to a colleague and he tried to log in in the same server via remote desktop (for some other reason). It took about a minute to get to the login screen, a minute to open the control panel, a minute to open the performance monitor, ... Icons were loading maybe one per second. We saw the following (from memory): CPU: 2% Avg. Queue Length: 50 Pages/sec: 115 (?) There was no other considerable activity on the server. The server seldom serves some ASP.NET pages, which became also very slow in this time. The relevant configuration is as follows: Windows 2003 SEAGATE ST3500631NS (7200 rpm, 500 GB) LSI MegaRAID based RAID 5 4 disks, 1 hot spare Write Through No read-ahead Direct Cache Mode Harddisk-Cache-Mode: off Is this normal behaviour for such a configuration? What measurements could give further clues? Is it reasonable to reduce the priority of such copy I/O and favour other processes like the remote desktop? How would you do that? Many thanks!

  • Testing for disk write

    - by Montecristo
    I'm writing an application for storing lots of images (size <5MB) on an ext3 filesystem, this is what I have for now. After some searching here on serverfault I have decided for a structure of directories like this: 000/000/000000001.jpg ... 236/519/236519107.jpg This structure will allow me to save up to 1'000'000'000 images as I'll store a max of 1'000 images in each leaf. I've created it, from a theoretical point of view seems ok to me (though I've no experience on this), but I want to find out what will happen when there will be directories full of files in there. A question about creating this structure: is it better to create it all in one go (takes approx 50 minutes on my pc) or should I create directories as they are needed? From a developer point of view I think the first option is better (no extra waiting time for the user), but from a sysadmin point of view, is this ok? I've thought I could do as if the filesystem is already under the running application, I'll make a script that will save images as fast as it can, monitoring things as follows: how much time does it take for an image to be saved when there is no or little space used? how does this change when the space starts to be used up? how much time does it take for an image to be read from a random leaf? Does this change a lot when there are lots of files? Does launching this command sync; echo 3 | sudo tee /proc/sys/vm/drop_caches has any sense at all? Is this the only thing I have to do to have a clean start if I want to start over again with my tests? Do you have any suggestions or corrections?

  • the effect of large number of files on disk space in unix filesystems

    - by user46976
    If I have a text file in Unix that contains N-many independent entries (e.g. records about employees, where each employee has a separate record), is it expected that this file will take up less space than if I split the file into N files, each containing the entry for one employee? in other words, can one save significant space on unix file systems by concatenating many files together, or is the difference negligible? thanks.

  • Relayout LVM Disk

    - by Tom
    I have an Ubuntu 11.10 system with two 500GB disks. The partition tables look like this: /dev/sda1 primary 465.52GB /dev/sda2 extended 243.17MB -> /dev/sda5 logical 243.14MB /dev/sdb1 primary 465.76GB sda1 and sdb1 are in a single LVM physical volume group containing a single logical volume containing a single logical filesystem which is mounted as /. sda5 is mounted as /boot. The problem comes when I want to upgrade to Ubuntu 12.04, which requires at least 247MB free on /boot. So I need to reduce the size of sda1 so that I can increase the size of sda2 and sda5. How the heck do I do that? I can find how to shrink the logical volume group, but I'm not at all clear on how to clear out the end part of sda1 so that I can reduce the physical volume group. Does pvresize just deal with this automagically? Or is that wild wishful thinking? I guess the alternatives are to back everything up onto something or other and recreate the thing from scratch or find out whether GRUB2 supports using LVM for /boot.

  • Why is an Ext4 disk check so much faster than NTFS?

    - by Brendan Long
    I had a situation today where I restarted my computer and it said I needed to check the disk for consistancy. About 10 minutes later (at "1%" complete), I gave up and decided to let it run when I go home. For comparison, my home computer uses Ext4 for all of the partitions, and the disk checks (which run around once week) only take a couple seconds. I remember reading that having fast disk checks was a priority, but I don't know how they could do that. So, how does Ext4 do disk checks so fast? Is there some huge breakthrough in doing this after NTFS came out (~10 years ago)? Note: The NTFS disk is ~300 GB and the Ext4 disk is ~500 GB. Both are about half full.

    I had a situation today where I restarted my computer and it said I needed to check the disk for consistancy. About 10 minutes later (at "1%" complete), I gave up and decided to let it run when I go home. For comparison, my home computer uses Ext4 for all of the partitions, and the disk checks (which run around once week) only take a couple seconds. I remember reading that having fast disk checks was a priority, but I don't know how they could do that. So, how does Ext4 do disk checks so fast? Is there some huge breakthrough in doing this after NTFS came out (~10 years ago)? Note: The NTFS disk is ~300 GB and the Ext4 disk is ~500 GB. Both are about half full.

  • GParted in UBUNTU shows entire disk as UNALLOCATED SPACE

    - by msPeachy
    Good day to everyone. I hope someone can help me with my problem. I have a dual boot Windows and Ubuntu system. I recently encountered an hd0 out of disk error and wasn't able to boot Ubuntu. So I booted into Windows, after 2 to 3 times of booting and rebooting Windows, I tried booting Ubuntu but still I get the hd0 out of disk error. I decided to run Ubuntu from LIVEUSB to try to fix my Ubuntu partition using GParted, but when I run GParted, it shows my entire disk as UNALLOCATED SPACE! The strange thing is that Nautilus still shows and mounts my partitions. Also every time I boot into Windows , my partitions exists and I am able to read and write to them. I have no idea what is wrong. Please help! I can't stand using Windows since most of the tools I use are in Ubuntu. I don't mind reinstalling Ubuntu. In fact I already tried reinstalling using the LIVEUSB but I wasn't able to, since GParted or the Ubuntu installer itself does not recognized my partitions and shows the entire disk as unallocated space. I am currently running Ubuntu from LIVEUSB. Here's the outpuf of sudo fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xb30ab30a Device Boot Start End Blocks Id System /dev/sda1 * 2048 104869887 52433920 83 Linux /dev/sda2 104869888 105074687 102400 7 HPFS/NTFS/exFAT /dev/sda3 105074688 156149759 25537536 7 HPFS/NTFS/exFAT /dev/sda4 156151800 625153409 234500805 f W95 Ext'd (LBA) /dev/sda5 156151808 169156591 6502392 82 Linux swap / Solaris /dev/sda6 169158656 294991871 62916608 7 HPFS/NTFS/exFAT /dev/sda7 294993920 471037944 88022012+ 7 HPFS/NTFS/exFAT /dev/sda8 471041928 625121152 77039612+ 7 HPFS/NTFS/exFAT When I run, sudo parted -l, I got this error message: ubuntu@ubuntu:~$ sudo parted -l Error: Can't have a partition outside the disk!
