  • How to use Hardware RAID in Ubuntu Server

    - by user2071938
    I have an Adaptec RAID-Controller and created an RAID-1(Mirroring) succesfully. Now I have installed Ubuntu Server 12.04.3. When I type fdisk -l I get this output: bf@fileserver:~$ sudo fdisk -l Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/sda doesn't contain a valid partition table Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sdc: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders, total 156301488 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: 0x0004c454 Device Boot Start End Blocks Id System /dev/sdc1 * 2048 499711 248832 83 Linux /dev/sdc2 501758 156301311 77899777 5 Extended /dev/sdc5 501760 156301311 77899776 8e Linux LVM Disk /dev/mapper/fileserver--vg-root: 75.6 GB, 75606523904 bytes 255 heads, 63 sectors/track, 9191 cylinders, total 147668992 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: 0x00000000 Disk /dev/mapper/fileserver--vg-root doesn't contain a valid partition table Disk /dev/mapper/ddf1_Data: 1000.1 GB, 1000065728512 bytes 255 heads, 63 sectors/track, 121584 cylinders, total 1953253376 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/mapper/ddf1_Data doesn't contain a valid partition table Disk /dev/mapper/fileserver--vg-swap_1: 4160 MB, 4160749568 bytes 255 heads, 63 sectors/track, 505 cylinders, total 8126464 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: 0x00000000 Disk /dev/mapper/fileserver--vg-swap_1 doesn't contain a valid partition table The 80 GB HDD is for the System The 1000.2 GB HDD should be for my data.

(I have two 1000.2 GB HDDs in an Raid-1 Array) dmraid gives me bf@fileserver:~$ sudo dmraid -r /dev/sdb: ddf1, ".ddf1_disks", GROUP, ok, 1953253376 sectors, data@ 0 /dev/sda: ddf1, ".ddf1_disks", GROUP, ok, 1953253376 sectors, data@ 0 so It seems to be ok? But how do I partitionate this disks and which one should I mount(sdb or sda?) Hope you can help me thx Florian

  • How to unsquash and mount arch linux live CD

    - by steffen
    I am following this manual to install Arch Linux from within another Linux distro with the help of an Arch Linux live CD. Here is what I did: sudo mount -o loop Downloads/archlinux-2012.11.01-dual.iso arch_iso/ unsquashfs -d squashfs-root/ arch_iso/arch/x86_64/root-image.fs.sfs This results in a directory squashfs-root/ containing one file: root-image.fs I assume that this is not what I want. I want to see something that looks like a Linux root folder. If I follow these steps: "mount the file system" with mount -B /squashfs-root ${livecd_arch} and mount -t proc /proc ${livecd_arch}/proc, I get error messages like: mount: mount point /home/me/arch_root//proc does not exist What am I missing? Thanks!

  • Is my Windows partition too far down on the disk?

    - by Trevor Alexander
    I have /boot/ on /dev/sda1 (1GB), followed by my Linux root LVM on /dev/sda2 (1.3GB). Finally, I installed Windows 7 on /dev/sda3 in the remaining 700GB of space. When I select Windows 7 in the grub menu, I get something like the following error and am thrown to grub4dos: find --set-root --ignore-floppies --ignore-cd /bootmgr Error 15: file not found Unable to locate necessary tables for adjustment. None of the options in grub4dos return anything but the above error. I heard that 1TB is the upper limit for locating Windows 7 partitions; is this true? How can I fix the above?

  • Disabling the Driver Region on a Mac

    - by Cawas
    So, this is the first time I try to watch a DVD disc on my (new) Mac and I wonder if I can keep it as fresh-new by not choosing any region and just play discs from anywhere. I understand the media industry made that lock for copyright and whatever, but do I absolutely have to choose a region to be able to play disks, even if I got original ones from different places? Why can I "change region" just 5 times, why even allowing changing? Also, on a side-note, I wonder how to disable the regular DVD Player.

  • Her microphone produces white noise, after a while?

    - by Wolfpack'08
    When my friend Skypes with me or gets on FB Video with me, her sound works fine... at first. After a bit, it starts sounding like loud static. It happens more frequently as we restart video chats, until it happens as soon as we open video chats. We usually restart her PC to fix the issue. Is there a process we could kill, maybe? Skip that question, if you will, and jump to these two: How do we fix this? Why is this happening?

  • How to disable taskbar transparency in Windows 8?

    - by yzorg
    This post from how-to-geek to disable Aero in Win7 and Vista no longer works in Windows 8. Is there another way to disable taskbar transparency in Windows 8? Edit: On Win8 Aero was removed but the taskbar is transparent (the desktop background picture is slightly visible 'behind' the taskbar). When I'm using the taskbar to switch programs I don't like seeing artifacts 'bleeding-through', I find it distracting.

  • Using USB drive in Windows and Linux properly

    - by sashkello
    What is the proper way of using a USB hard drive or stick between Linux and Windows? (I'm using Linux Mint 14 and Windows XP on different machines) Should I set it up somehow so that all the files are shared and reused safely between Linux and Windows? The question comes from the recent problem I had. I've created and edited a few folders through Linux and they are not working on Windows now (folder is not accessible. The file or directory is corrupt). While I dealt with that problem, what would be the way of ensuring this doesn't happen again?

  • Are Motherboards for the Acer Aspire One AOA150 Netbook Compatible with the AOA110?

    - by Mindstormscreator
    I have an Acer Aspire One ZG5 AOA110-1588 netbook, and the motherboard doesn't have a port for a SATA 2.5 inch hard drive; it only supports this slow 8GB SSD type drive. Through research I've discovered that the AOA150 motherboards do have a SATA slot, and the bottom plate of these laptops have an appropriate protrusion for the drive to fit in (for example, compare this to this). The AOA110 and AOA150 models are very similar in appearance and specs. I've even seen tutorials that involve soldering a SATA connector onto the AOA110's motherboard, essentially creating an AOA150 motherboard (right?) So, could I just swap out the motherboard in my netbook with the MBS0506001? (I'd post another link to the actual board but can't because of the spam prevention...) I assume I would also need to purchase and replace the bottom cover with a larger one and possibly get a hard drive caddy as well...? Thanks!

  • How to reference other locations in making multi-boot live cd

    - by Nrew
    There is a tool in pen drive linux that allows you to boot directly with multiple iso files. And here is a sample in the menu.lst which allows you to choose which iso file you want to boot. title Fedora 13 find --set-root /Fedora-12-i686-L.iso map /ubuntu-10.04-desktop-i386.iso (0xff) map --hook root (0xff) kernel /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper persistent iso-scan/filename=/ubuntu-10.04-desktop-i386.iso splash initrd /casper/initrd.lz I'm just using it on my 8gb flash drive and the location of the iso file is in the flash drive itself. Is it possible to reference other locations. So that I could boot from it, without limitations. because the flash drive can only contain 8gb of data. Is it possible? Anyone here tried this before?

  • Log into another XP machine's SQL Server with a different userid? (WORKGROUP, not domain)

    - by Eric H.
    I have two machines at home, both XP Pro SP3. I have no domain controller, so they're both just in WORKGROUP. How can I, using Windows Authentication, log into an instance of SQL Server running on the other machine? Whenever I try it, it seems to try to login as 'Guest', even though I have entered the machine name (OTHER-DESKTOP), and login (OTHER-DESKTOP\otheruser) in the User Accounts Control Panel box. It works fine if I use sql server name and password, so I know the server is running. Any clues?

  • Config xampp never to cache pages from localhost

    - by Michael Mao
    Hello everyone: I am not a webmaster, and that was exactly the reason why I installed XAMPP 1.7.2 on Windows XP SP2 instead of manually configuring Apache, MySQL and PHP to cooperate each other. Now I am having to problem to disable caching pages from localhost. Some suggested just force the browser not to cache, using Firefox web developer bar or something similar; but I feel it would be better if I could configure the Apache server in XAMPP to never allow pages from localhost to be cached. I guess this is done somewhere in httpd.conf? LoadModule cache_module modules/mod_cache.so Would this module be helpful in this case? Doc here : mod_cache I am not very sure this would resolve the problem. Could anyone confirm this approach feasible? I'd like to work it out myself, given the fact that I am on the right track... Many thanks in advance

  • Why don't I have a "Web Service References" menu item in excel/VBA?

    - by Draemon
    I'm trying to consume a SOAP web service from excel. Now according to This article (and confirmed by other articles and MSDN) if I do the following: Install the web services toolkit (I've installed v2.01) Install SOAP Toolkit 3.0 Add a reference to Microsoft Soap Type Library (I've tried v3.0 and an older one) I should get a "Web Service References" menu item in the Tools menu but I don't. I've also tried adding every reference that seemed to have anything to do with SOAP or XML, but it hasn't helped. Any ideas?

  • scanner no longer working windows 7

    - by Sackling
    I have a windows 7 64 pro machine that for some reason no longer works with a brother all in one printer/scanner, when I try to scan. This happened seemingly out of nowhere. Printing still works. When I try to scan from photoshop, photoshop crashes. When I try to scan from device manager (which takes a really long time to access the printer) I get an error saying: "operation could not be completed. (error 0x00000015). the device is not ready. I tried uninstalling/reinstalling the printer and drivers. I have also run the brother driver cleaner and then reinstalled and get the same results every time. I had access to another HP all in one. And very strangely When I setup this new printer I have a similar issue that happens. I am able to print but when I try to scan from the HP tool nothing pops up. So my thoughts are it is something to do with the twain driver? But I don't know what to do or check. Any help is appreciated.

  • ffmpeg open webcam using YUYV but i want MJPEG

    - by Pavel
    I need ffmpeg to open webcam (logitech c910) in MJPEG mode, because the webcam can give ~24 using MJPEG "protocol" and only ~10 fps using the YUYV.

  • Win 7 accessing large files uses 100% RAM

    - by user181276
    Running Win 7 64-bit SP1 with 8 GB RAM. I first noticed this problem when using the GUI to copy some large (5+ GB) files from one disk to another. What happens is the physical memory in use rises quite quickly to 100% and the system comes to a crawl. If I just start to access the file in a media player (it is a movie) the memory usage climbs up slowly but eventually reaches 100%. When copying the same files via XCOPY I do not have this problem. Using RAMMAP I see most of the memory usage is under "Mapped File" and is allocated under the "Active" column. If I select "Empty System Working Set" the RAM usage drops back down but then starts to climb back up. Any ideas on what I can check/test to eliminate this issue?

  • Digital Blue Digital Movie Creator 3.0 driver

    I'm having a complete 'mare of a time trying to use my schools Digital Blue cameras. We've got the model 3 ones, but can't find the driver disc and using the Windows Hardware Installation Wizard gets me no where! Can you help me to find the driver? When I've used it at my old school it had a piece of software called the Digital Movie Creator, which I've heard you can use to make stop-motion films, which is what I want to do! This is what it looks like http://www.amazon.co.uk/Digital-Movie-Creator-1GB-Card/dp/B000LP30LA/ref=sr_1_2?ie=UTF8&s=software&qid=1265928833&sr=1-2

  • How to Automate .inf PnP Windows 7 Drivers with Wildcard?

    - by Dos_Probie
    I am trying to automate the PnP driver installs for Windows 7 with either of the below batch files via For loop and wildcard for the .inf file.

  • aTop like tool for OSX

    - by Maciek Sawicki
    I'm trying to debug some issues with my Mac. This machine is used as continuous integration server. It stops responding from time to time. I think it could be some software issue, since the machine is working (so i.e. it's not a kernel panic) - that is when I go to the server room I see the login screen and I can move the mouse. Unfortunately I can't login neither directly nor by VNC or SSH. There is a nice tool that helps in debugging this type of problem called aTop. It's like top but with history. Unfortunately it's Linux-only software. Is there any tool that is similar to aTop for OSX?

  • Turn off "unknown publisher" message for older Windows application?

    - by MikeJ
    Anyone know how to turn off or suppress the "unknown publisher" message for a specific application? The application is a legacy version of Delphi that we use to update a LOB application. I thought clicking, run as administrator would fix this and I don't want to turn off UAC entirely for security safety reasons. Anyone know how to tell Windows 7 that Borland or at least delphi.exe is a trusted application?

  • Improving Chrome performance on OSX

    - by Giannis
    There are a number of sites that do not display properly on Safari and I need to switch to Chrome. Although when the content of the sites requires flash player, Chrome will consume a significant amount of CPU. Running more than 3 windows, will cause my MBP to overheat, start the fans, and reduce battery life way more than Safari. What I am looking for is suggestions on ways to improve performance of Chrome running flash. I know Safari is optimised for OSX, but any improvement is welcome. Following I have a demo to display the issue. I am running same youtube video on Safari 6 and Chrome 21,both updated,at the same time. Both browsers have been reseted and have no extensions. This is run on MBP 13" 2012 with 2.9 i7 running OSX 10.8.1. p.s If any additional details can help please let me know.
