• SQL 2008 Mirroring, how to failover from the mirror database?

  - by Luis

  I have configured a database mirroring setup in SQL 2008 using the High-safety, Synchronous mode, without automatic failover. I don't have a Witness instance. Regarding high availability, I understand Mirroring is a better strategy than Log Shipping (faster and smoother failover), and cheaper than Clustering (because of license and hardware costs). According to the MS docs, to do the failover you need to access to the Principal database and in the "Mirror" options click the "Failover" button. But I want to do this from the Mirror database, because what would be the benefit as all this setup is being done in case the Principal server knocks down? Evidently I am missing something. If Mirroring is not a solution for server downtime (as would be Clustering, if I understand correctly), then which practical (i.e. real world examples) cases would benefit from Mirroring for high-availability purposes? Thank you very much for your response! I really need some enlightment.

• How to access an SD card from a virtual machine?

  - by Punit Soni

  I want to format an SD card from my Linux virtual machine. I have a built-in SD card reader in my laptop. I tried using VirtualBox and VMware Player and installed Ubuntu 10.04 guest. None of them are showing the SD card reader as a device. I can access the SD card from the Windows host. I am not interested in solutions using shared folders as I want to access the SD card as hardware (it should show up in /dev). I basically want to set up the SD card for BeagleBoard, but I don't want to install physical Ubuntu in my PC.

• Windows SBS 2011 DNS Role (service) failing & needing restarting

  - by HaydnWVN

  Have a Windows SBS 2011 with Exchange that is handling all DNS for the network. Since getting a 3rd party (Hardware & Support) to setup a recieving FTP service and restricting Exchanges memory useage for another 3rd party product (Stock software) the local network seems to periodically 'lose the internet connection'. Delving deeper I found that the DNS service is somehow failing/stopping without the actual service on the server reporting such (nothing in event logs). A simple restart of the 'DNS Role' on the server solves the problem. The manager onsite reports that he has to do this most days in the afternoon - yet not at the same time and other days it works fine without a restart being required. I'm unable (lacking sufficient SBS2011 knowledge) to diagnose this further, ideally I would like the DNS Role to report (and log) the failure, then automatically restart itself.

• Resize NTFS System Partition on Perc 6/i RAID

  - by Cipher42

  I've inherited a Dell server that is running out of space on C:. I'd like to quickly and painlessly resize the C drive with partitioning software. However, the RAID card is causing me some troubles. I've resized plenty of desktops in my time, but never a server with hardware RAID. Can anyone recommend software that is GUARANTEED to work with the Dell PERC 6/i? Hopefully someone has resized the system partition with this RAID card before! :) Of course, proper backups are available but I'd be more comfortable with a tried and true solution to save the headache of the restore.... Thanks in advance!

• Is there any way to play Netflix (stream) in Windows Media Player 11?

  - by Not So Sharp

  Googling for a solution yields a ridiculous page on eHow that instructs to insert a DVD from Netflix. But I am not interested in the DVD option. I am only interested in streaming and unfortunately none of my browsers (IE, FF, Chrome) uses the hardware acceleration built into my video card. The only way I can play non-choppy video on my PC is via Windows Media Player, but WMP doesn't list Netflix as one of the supported online stores for some reason. Any idea or trick how stream Netflix on WMP 11 instead of a browser?

• unable to install new versions of linux on my PC

  - by iamrohitbanga

  I have an MSI-RC410 motherboard with onboard ATI Radeon XPress 200 series Graphics card. I have used OpenSuse-11.0 on my PC for over an year. but when I tried to upgrade to OpenSuse-11.1, I managed to install it only to find that several features were missing. for example /dev/cdrom was missing. Also install DVD of Fedora 11 did not work. I have also tried Ubuntu-9.10 live cd. When I boot from the CD i get the initramfs command prompt. Still able to install old versions of these OSs. What is the reason for this behavior? Does it have to do anything with the new version of the linux kernel not being compatible with my hardware? What should i do to install new versions of Linux?

• Fedora Installation with software repository in DVD does not work

  - by Raks

  I bought a new assembled PC with processor as Core-i3(2120) and Intel H61 motherboard and was trying to install Fedora 16 from a DVD. This DVD contains all the packages so that installation does not require to download packages from internet. I have used this DVD to install Fedora 16 offline many a times though in machines with different hardware configuration. But in this new machine when the installation reaches the stage wherein it asks for Software repository selection I select CD/DVD but the system fails to read the media and throws up an error that it cannot detect the media. THe LED in the DVD writer also indicate that the DVD is not being read. Now there is neither a problem with the DVD or the DVD drive because the installation started from the DVD itself. So what could the problem be, anything in the BIOS that is causing the problem, Is there any way I could utilize the packages already existing in the CD so that I save downloading the packages from DVD

• Windows 2008R2 two node failover cluster creation fails

  - by Francois Wolmarans

  We have just installed two Windows 2008R2 Enterprise machines with identical hardware. When running the cluster validation everything is ok. When creating the cluster it fails with the following error: An error occurred while creating the cluster. An error occurred creating cluster 'CLUSTER04'. The parameter is incorrect The logfile on the first node where we are running our config from, does not show any errors. On the second node we get: The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk. I've double checked and all communication between the servers are fine. Even when creating a one node cluster it gives the error. There are other failover clusters we have setup without any issues.

• How to fully use the 4G in my Laptop under Ubuntu 9.10 - 32-bit

  - by jfmessier

  I have a Toshiba A100, which I upgraded to 4G of RAM. The hardware startup indeed shows 4G of RAM, and I recently installed Windows 7, just to see how it behaves on it. So far so good, it displays 4G of RAM. Not that I tried to use it all, but it displays it. Previously under XP, I also would see 4G of RAM. But under Ubuntu 9.10 (32 or 64 bits), it only displays 2.9 G of RAM. And my kernel is the "pae" compiled one, which is supposed to do the trick to work around the 32-bit CPU limitation. How can I get Ubuntu to fully use my 4G of RAM ?

• Use an unsigned driver in Windows 7 x64

  - by rjmunro

  I'm trying to use the RBC9 SpaceNavigator TEST x64 build drivers for my SpaceNavigator 3d joystick so that it can work as a normal joystick in games like Quake. Unfortunately, I get the error "This version of windows requires all drivers to have a valid digital signature" and in the "Device status" in device manager, I get "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)". Is there a way to work around this issue?

• Keyboard doesn't load in windows xp after Alureon infection

  - by alureonissue

  AVAST detected alureon in a number of system files including atapi.sys and kbdclass.sys iple I quarantined those files, and restarted my machine. After restarting, my keyboard and cdrom did not work (I assumed those drivers would be automatically replaced, but was apparently wrong.) I went into device manager, and checked for hardware changes, it fixed the cdrom (which works now) and looked as though it fixed the keyboard as well. It did not. After multiple reboots the keyboard is still not recognized. It works up until the XP login screen loads, after which it is completely unresponsive. Any advice would be appreciated. Thanks :)

• XP boot timer=> set, but does nothing?

  - by mark

  My PC has XP Pro and the boot.ini file looks like this: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(2)\windows [operating systems] C:\CMDCONS\BOOTSECT.DAT="Microsoft Windows Recovery Console" /cmdcons multi(0)disk(0)rdisk(0)partition(2)\windows="eXPee Pro" /noexecute=optin /fastdetect Up until about a week ago it would just time-out and boot normally. I haven't made any hardware changes at all. Now, when the system boots it just sits there and waits for me to hit -enter-. I've searched all over for explanations & possible causes, but found nothing which seems to relate. Anyone here have any idea what may have caused the timer to simply quit working like that ? (BTW, the system clock works just as it ever did and keeps time precisely.) Thanks.

• Reduce the I/O priority of Windows Backup (Windows Server 2008 R2)

  - by HelloSam

  I have a PostgreSQL running on Windows Server 2008 R2 x64 box. And I have scheduled a backup everyday from the RAID 1 DB disk to a dedicated standalone disk. They are SAS 15k on Dell PERC 6i. I am using the built-in Windows Server Backup for purpose. The problem is, whenever the backup process is kicked in, the database performance is hogged. I would say almost a 10x of performance reduction. From the resource monitor, the disk queue is in the double digit range when backing up, and less than 1 during the day. The disk activity is like ~30-50MB/s during backup, so I guess the hardware is acting normally, though wbengine.exe takes up most of the portions. I think reduce the IO priority of the backup process would be an answer, but I couldn't find a way to. Tuning process CPU priority does not seems to help.

• Keep-Alive header not sent from Tomcat 5.5 http connector?

  - by Codek

  Hi, We're currently using a hardware load balancer, which then goes to Apache and that then goes to Tomcat 5.5 via the AJP connector. We've decided to dump apache for various reasons - In our current system it doesnt provide any advantage. However when I look at the headers sent when we do this, the "Keep-Alive: timeout=15 max=96" header doesnt get sent when you use the tomcat http connector Interestingly, i can find no documentiation on "keepalivetimeout" for tomcat5.5, but i can for tomcat6. But neither can i find evidence that tomcat5.5 doesnt support this setting. here's my connector: <Connector port="8090" maxHttpHeaderSize="8192" maxThreads="400" minSpareThreads="150" maxSpareThreads="300" enableLookups="false" connectionTimeout="2" maxKeepAliveRequests="400" disableUploadTimeout="true" /> So; Is there any way I can specify the keepalive timeout if we use the http connector with tomcat 5.5, and force this header entry to be sent? Thanks, Dan

• One bigger Virtual Machine in Cloud

  - by flyer

  I just setup virtual machines on one hardware with Vagrant (this is just a test environment, not production!). I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with e.g. 12 cores? ------------------------------- | VM (12c) | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | VM (4c) | VM (4c) | VM (4c) | ------------------------------- | Bare Metal (8c) | ------------------------------- I need this information to have a bigger picture to continue.

• Win 7 BSOD stucks at dumping

  - by AFO

  Recently Ive been getting frequent bsods, which always gets stuck at dumping without finishing it, with most of them showing no error messages. This never happened before i upgraded to new rams, but 2 passes of memtest86 turned out fine. Tried reinstalling windows, problem still there. Tried initiating a manual crash, and that did create a successful dump. The SSD win 7 is on doesn't seem to have any problems, crystaldisk says its healthy. Varied the cpu multiplier between stock and +500Mhz, crashed regardless. Left voltage control to auto. Im fairly sure its a hardware problem, just cant pinpoint which specific part(s). The specs- Windows 7 x64 (1 day old) 955 x4 BE c3 (running at stock) (3.5 years old) GA-970A-D3 (1.5 years old) Gigabyte 6950, unlocked to 6970 (still at 6950 speeds) (<3 years old) 2x4GB 1600 CL9 HyperX Blu (running at 11-11-11, default motherboard setting) (<1 month old) Plextor M5s (around 5 months)

• Back / Forward mouse buttons do not work in VMWare Workstation 6.5 Guest OS

  - by Tim Lara

  I am using a Logitech G9 mouse and running VMWare Workstation 6.5.3 on Vista x64. The guest OS is Win XP, and has the most current version of VMWare Tools installed. Left / right buttons and mouse wheel scrolling work fine in the guest OS, but the back / forward buttons are apparently not recognized. I have tried installing the Logitech software inside the guest OS as well, but it still did not recognize the back / forward buttons. (I didn't really expect this to work since the guest OS doesn't actually see the mouse hardware as a Logitech G9 directly anyway.) I vaguely remember seeing something a while back about editing the virtual machine config file to specify a 5-button mouse rather than the default 3-button setup, but I can't seem to find any specifics on how to do so in the VMWare documentation. Does anyone know if such a workaround exists, or is 5-button mouse functionality just not supported?

• Mac Mini 1.66 no sound on Windows 7

  - by Steph

  I've tried everything I could to get the sound working. I've tried to install the drivers from the Snow Leopard disk, then I went and got the latest RealTek drivers from the RealTek website. Then I read that old Mac mini's could have an integrated Cirrus chip, and I tried to grab the latest driver from the website, and it appeared to install, but nothing. There's also nothing listed under Sound and ... in the Device Manager. I've tried to manually include a legacy driver, which worked for RealTek but not for the Cirrus driver. Of course it said there was no RealTek hardware install, which makes me think it's a Cirrus chip. Any further suggestions or thoughts would be really appreciated. This is a Mac Mini 1.66. I'm also not sure how to be able to detect what card is integrated into the system, so that would be helpful too (remembering that there's no driver installed). Even just to get the chip type would be great to confirm.

• Why can't I play YouTube clips properly anymore?

  - by NoCanDo

  I haven't got the faintest idea what happened, but since about 3-4 days now I can't play any clips on YouTube properly at all. Proper as in continuously without loading, pause, playback, pause, loading, playback, pause, loading, playback, etc. I haven't changed anything hardware nor software-wise. On the other hand I can play Break.com, Viddler, Liveleak, Metacafe without any trouble. I tried my own tips, but that hasn't helped me at all. What on earth happend? Is it me, or is it YouTube? I'm using Firefox 3.6 Beta 5. But the issue is the same on Chrome as well as on Internet Explorer.

• Can a virtual mikrotik box bridge a hyper-v internal network with a hyper-v external network?

  - by mcfrosty

  I am trying to set up a Mikrotik router as a transparent firewall on my network. I got the machine working on a hardware MT box, but my boss wants the MT virtualized. I have been trying the set up where my virtual windows box talks to the Mikrotik via private or internal network on the Hyper-V host. I can get the two machines to talk, but as soon as I set up a bridge on the MT, all traffic ceases between the two. Is it possible to create a bridge for this purpose (having the MT silently in front of my firewalled server)? I could really use some help.

• Is Hyper-V Server 2008 working on Intel's Atom platform

  - by Josip Medved

  Did anybody try to install Hyper-V on Intel Atom platform? Hyper-V requires: x64 compatible processor with Intel VT or AMD-V technology enabled Hardware Data Execution Prevention (DEP) It seems that both requirements are satisfied with Atom as processor. However, I wonder whether there is some blocking issue (e.g. BIOS that does not support it) since all Atom motherboards I checked had quite old north/south-bridge. My intentions are to run two low-requirements virtual machines (embedded Linux), so performance should not be an issue.

• Format an external hard disk

  - by Alex

  I am trying to format an external hard disk to FAT32 (I need it to work with some hardware that expects it to be in FAT32). When I am trying to format it via windows the only option I'm getting is to format it to NTFS. Another strange thing is that when I am trying to format one of my own partitions (on the hard disk that is running the OS) I can do it only in NTFS while another partition my OS can format in both NTFS and FAT32. What can cause such a behavior and how can I format the external hard disk to FAT32?

• Intel Xeon vt-d query

  - by deploymonkey

  Does Xeon westmere ep (xeon 56xx series) have vt-d (=iommy / direct io) or does intel TXT (Intel® Trusted Execution Technology) include vt-d? I'm at a loss. I've been researching current processors for an important project for some time now. I need to know, if the xeon 5600s (Westmere EP) include vt-d (iommu/directed io/pci passing) because the system will run virtualized guests. This enables direct hardware access eg. pci passthrough, in xen for example. It seems that the 5600s TXT should incorporate vt-d and that xeon 5600s should include vt-d as they are ramped up 5500s, but there is no conclusive answer anywhere. Intel's processor comparison only states that 5500s have vt-d and no TXT and 5600s have no vt-d but TXT. I'd be really grateful if anybody could clear this up and possibly even provide a citation. Thanks a lot.

• Is it possible to download minimal drivers on Windows, without the extra software packages?

  - by Anton Gogolev

  The situation in all its glory: 30 megs for ATIs' "Display Driver Only". Almost 100 megs for NVidias' GeForce/Ion bloatware. 300 megs for an HP printer driver with immense amount of crap 30 megs for a Realtek integrated sound card driver. 50 megs for a mouse driver ...and dozens and dozens of other similar examples Additinally, UI/UX on vendors' sites is really terrible: I have to carefully pick and choose the exact model of my whatever, although this packages do contain drivers for pretty much every possible hardware model out there. My question is: How and where can I download true minimal drivers without all these ATI "Installation Managers", Realtek GUIs, ASUS tools, etc.?

• Failures when copying between two external drives on the same controller

  - by Krzysztof Kosinski

  I'm encountering a weird problem which is present both on Ubuntu 9.10 and 10.04, on two different machines. When trying to copy between two external drives connected to the same USB controller, the transfer will randomly hang at some random time (after copying 300MB, 1GB, 10GB - it doesn't appear to depend on the dataset being copied). The hang appears to happen faster in 10.04. It appears to happen slower if both drives are connected to a hub. If the drives are connected to 2 distinct physical ports on the machine, the hang will be very fast. Hangs cannot be reproduced if: Data is copied from the first external drive to an internal drive, then to the second external drive Drives are connected to different USB controllers, for example the first one is connected to the built-in controller and the second one via an external PCMCIA controller. lspci says the first machine has an Intel ICH9 USB controller, the second an Intel ICH4. Is this a hardware problem, a kernel problem or a software issue? I used Nautilus when copying the files.
