• Ubuntu doesn't "see" external USB Hard Disk

  - by Mina Michael

  It's NTFS. It's USB2. I'm using Ubuntu 13.04. It works perfectly fine on Windows (which excludes cable and hardware problems). I have two Ubuntu computers and it's not detected on either. It's about 500 GB. Edits: Following the first link, I input sudo lsusb in a terminal; before and after connecting the HDD. The difference was Bus 001 Device 012: ID 14cd:6116 Super Top M6116 SATA Bridge. There it is! ("sata bridge" used to appear in a windows notification when I plugged in the HDD in!). ...This means that Ubuntu detects it but is it not mounting it? I tried this: sudo mount /dev/sdb1 /mnt But gives this: mount: special device /dev/sdb1 does not exist I also tried: sudo mount /dev/sdc1 /mnt but it stays with no output forever. I left it in background for about 30 min.s. sudo fdisk -l gives out this: Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581808 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: 0xa42d04a3 Device Boot Start End Blocks Id System /dev/sda1 63 80324 40131 de Dell Utility /dev/sda2 * 80325 102481919 51200797+ 7 HPFS/NTFS/exFAT /dev/sda3 263874558 312580095 24352769 5 Extended /dev/sda4 102481920 263872511 80695296 7 HPFS/NTFS/exFAT /dev/sda5 263874560 310505471 23315456 83 Linux /dev/sda6 310507520 312580095 1036288 82 Linux swap / Solaris Partition table entries are not in disk order Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 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: 0x5822aaea Device Boot Start End Blocks Id System /dev/sdc1 2048 976769023 488383488 7 HPFS/NTFS/exFAT The part below "Partition table entries are not in disk order" takes about 5 minutes to appear.

IT SHOWED THE FILES!! The command sudo mount /dev/sdd1 /mnt worked after I typed in sudo fdisk -l!!! Thanks a million!! :) :)

• Automatically change resolution when not in dock

  - by jwir3

  I have Ubuntu 11.04 (yep, I know it's old news) on my Lenovo W520. At home, I have a dock with dual monitors. I have a pretty decent setup - things work almost perfectly (hence the reason I'm reluctant to upgrade... that and I'm not 100% sold on Unity). Anyway, the only annoyance I have is that when I'm on travel, I use the laptop screen. When I un-dock the laptop, I need to manually go into nvidia x-server settings and change the resolution from 'Auto' to 1920x1200, or it will think I have two screens, and my mouse pointer will be able to go way off the left side of the screen. This isn't a big deal, but I need to do it every time I restart the x-server (so if I reboot, or have to kill it, etc...) What would be really nice is if there was a way for it to automatically detect whether or not there is external monitors (which it seems to do already), and switch into the mode I select, depending on which monitors are connected. Is there any way to accomplish this? I've posted my xorg.conf file for reference. # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 270.29 (buildd@allspice) Fri Feb 25 14:42:07 UTC 2011 # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 275.19 ([email protected]) Tue Jul 12 18:35:38 PDT 2011 #Section "Monitor" # Identifier "Monitor1" # VendorName "Lenovo" # ModelName "ThinkpadLCD" # #HorizSync 28.0 - 33.0 # #VertRefresh 43.0 - 72.0 # #Option "DPMS" #EndSection Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "DELL U2410" HorizSync 30.0 - 81.0 VertRefresh 56.0 - 76.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "Quadro 1000M" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection Section "Screen" # Removed Option "metamodes" "DFP-0: nvidia-auto-select +0+120, DFP-6: nvidia-auto-select +1920+0" # Removed Option "metamodes" "DFP-0: nvidia-auto-select +0+120, DFP-5: nvidia-auto-select +1920+0" # Removed Option "metamodes" "DFP-0: nvidia-auto-select +1920+419, DFP-5: nvidia-auto-select +3840+0, DFP-6: nvidia-auto-select +0+0" # Removed Option "metamodes" "DFP-5: nvidia-auto-select +0+0, DFP-6: 1920x1200 +1920+0" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "NoLogo" "True" Option "TwinViewXineramaInfoOrder" "DFP-0" Option "TwinView" "1" Option "metamodes" "DFP-5: nvidia-auto-select +1920+0, DFP-6: 1920x1200 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection

• Misused mke2fs and cannot boot into system

  - by surlogics

  I installed Ubuntu with WUBI in Windows 7 64bit, and I had installed Mandriva 2011 with a disk. I tried to learn Linux with Ubuntu and misused mke2fs; after I reboot my computer, Windows 7 and Ubuntu has crashed. As I have Mandriva, I boot into Mandriva and found # df -h /dev/sda7 12G 9.8G 1.5G 88% / /dev/sda2 15G 165M 14G 2% /media/logical /dev/sda6 119G 88G 32G 74% /media/2C9E85319E84F51C /dev/sda5 118G 59G 60G 50% /media/D25A6DDE5A6DBFB9 /dev/sda9 100G 188M 100G 1% /media/ae69134a-a65e-488f-ae7f-150d1b5e36a6 /dev/sda1 100M 122K 100M 1% /media/DELLUTILITY /dev/sda3 98G 81G 17G 83% /media/OS # fdisk /dev/sda Command (m for help): p Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 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: 0xd24f801e Device Boot Start End Blocks Id System /dev/sda1 2048 206847 102400 6 FAT16 /dev/sda2 * 206848 30926847 15360000 7 HPFS/NTFS/exFAT /dev/sda3 30926848 235726847 102400000 7 HPFS/NTFS/exFAT /dev/sda4 235728864 976771071 370521104 f W95 Ext'd (LBA) /dev/sda5 235728896 481488895 122880000 7 HPFS/NTFS/exFAT /dev/sda6 727252992 976771071 124759040 7 HPFS/NTFS/exFAT /dev/sda7 481500243 506674034 12586896 83 Linux /dev/sda8 506674098 514851119 4088511 82 Linux swap / Solaris /dev/sda9 514851183 727246484 106197651 83 Linux Partition table entries are not in disk order I think I may used the following command mke2fs -j -L "logical"/dev/sda2 but I had forgotten what kind of partition it was before I transfered it into ext3. perhaps ntfs Data was not lost, and I can view my files as I could in Windows.

• Java Refuses to Start - Could not reserve enough space for object heap

  - by Randyaa

  Background We have a pool of aproximately 20 linux blades. Some are running Suse, some are running Redhat. ALL share NAS space which contains the following 3 folders: /NAS/app/java - a symlink that points to an installation of a Java JDK. Currently version 1.5.0_10 /NAS/app/lib - a symlink that points to a version of our application. /NAS/data - directory where our output is written All our machines have 2 processors (hyperthreaded) with 4gb of physical memory and 4gb of swap space. We limit the number of 'jobs' each machine can process at a given time to 6 (this number likely needs to change, but that does not enter into the current problem so please ignore it for the time being). Some of our jobs set a Max Heap size of 512mb, some others reserve a Max Heap size of 2048mb. Again, we realize we could go over our available memory if 6 jobs started on the same machine with the heap size set to 2048, but to our knowledge this has not yet occurred. The Problem Once and a while a Job will fail immediately with the following message: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. We used to chalk this up to too many jobs running at the same time on the same machine. The problem happened infrequently enough (MAYBE once a month) that we'd just restart it and everything would be fine. The problem has recently gotten much worse. All of our jobs which request a max heap size of 2048m fail immediately almost every time and need to get restarted several times before completing. We've gone out to individual machines and tried executing them manually with the same result. Debugging It turns out that the problem only exists for our SuSE boxes. The reason it has been happening more frequently is becuase we've been adding more machines, and the new ones are SuSE. 'cat /proc/version' on the SuSE boxes give us: Linux version 2.6.5-7.244-bigsmp (geeko@buildhost) (gcc version 3.3.3 (SuSE Linux)) #1 SMP Mon Dec 12 18:32:25 UTC 2005 'cat /proc/version' on the RedHat boxes give us: Linux version 2.4.21-32.0.1.ELsmp ([email protected]) (gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-52)) #1 SMP Tue May 17 17:52:23 EDT 2005 'uname -a' gives us the following on BOTH types of machines: UTC 2005 i686 i686 i386 GNU/Linux No jobs are running on the machine, and no other processes are utilizing much memory. All of the processes currently running might be using 100mb total. 'top' currently shows the following: Mem: 4146528k total, 3536360k used, 610168k free, 132136k buffers Swap: 4194288k total, 0k used, 4194288k free, 3283908k cached 'vmstat' currently shows the following: procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 0 610292 132136 3283908 0 0 0 2 26 15 0 0 100 0 If we kick off a job with the following command line (Max Heap of 1850mb) it starts fine: java/bin/java -Xmx1850M -cp helloworld.jar HelloWorld Hello World If we bump up the max heap size to 1875mb it fails: java/bin/java -Xmx1875M -cp helloworld.jar HelloWorld Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. It's quite clear that the memory currently being used is for Buffering/Caching and that's why so little is being displayed as 'free'. What isn't clear is why there is a magical 1850mb line where anything higher means Java can't start. Any explanations would be greatly appreciated.

• how to do android image animation

  - by user270811

  hi, i am trying to get a simple image animation going. i want to make it looks as if the helicopter's propeller blades are turning. i have 3 images for the helicopter, and i am showing one of these images depending on the animation progress. the problem is that all three images end up overlapping each other as opposed to just one image showing up at one time, thereby creating the animation. this is what i did so far, i even tried to clear canvas by doing this canvas.drawColor(Color.BLACK), but that would clear out the whole canvas, which is not what i want. this is what i have: 1) in the View class: static class Helicopter { private long mLastUpdate; private long mProgress = 0; private final float mX; private final float mY; private final Bitmap mHelicopter1; private final Bitmap mHelicopter2; private final Bitmap mHelicopter3; private final float mRadius; Helicopter(long mLastUpdate, float mX, float mY, Bitmap helicopter1, Bitmap helicopter2, Bitmap helicopter3) { this.mLastUpdate = mLastUpdate; this.mX = mX; this.mY = mY; this.mHelicopter1 = helicopter1; this.mHelicopter2 = helicopter2; this.mHelicopter3 = helicopter3; mRadius = ((float) mHelicopter1.getWidth()) / 2f; } public void update(long now) { mProgress += (now - mLastUpdate); if(mProgress >= 400L) { mProgress = 0; } mLastUpdate = now; } public void setNow(long now) { mLastUpdate = now; } public void draw(Canvas canvas, Paint paint) { if (mProgress < 150L) { canvas.drawBitmap(mHelicopter1, mX - mRadius, mY - mRadius, paint); } else if (mProgress < 300L) { canvas.drawBitmap(mHelicopter2, mX - mRadius, mY - mRadius, paint); } else if(mProgress < 400L) { canvas.drawBitmap(mHelicopter3, mX - mRadius, mY - mRadius, paint); } } public boolean done() { return mProgress > 700L; } } private ArrayList<Helicopter> mHelicopters = new ArrayList<Helicopter>(); 2) this is being called in the run() of a thread: private void doDraw(Canvas canvas) { final long now = SystemClock.elapsedRealtime(); canvas.save(); for (int i = 0; i < mHelicopters.size(); i++) { final Helicopter explosion = mHelicopters.get(i); explosion.update(now); } for (int i = 0; i < mHelicopters.size(); i++) { final Helicopter explosion = mHelicopters.get(i); explosion.draw(canvas, mPaint); } canvas.restore(); } can someone help me? i have looked at a lot of the examples on the web on animation, they seem to always involve text, but not images. thanks.

• "shutting down hyper-v virtual machine management service"

  - by icelava

  I have a Windows 2008 R2 server that is a Hyper-V host (Dell PowerEdge T300). Today for the first time I encountered an odd situation; i lost connection with one of the guest machines but logging on physically it seems the guest OS is still running but no longer contactable via the network. I tried to shut down the guest machine (Windows XP) but it would not shut down, getting stuck in a "Not responding" dialog box that cannot be dismissed. I used the Hyper-V management console to reset the machine and it could not get out of resetting state. I tried to save another Windows 2003 guest machine, and it would be progress with its Saving state (0%). The other running Windows 2003 guest was stuck in the logon dialog. My first suspicion is perhaps one of the Windows update patches this week (10 Nov 2011) may something to do with it, which was still pending a system restart. Well, since I could not do anything with Hyper-V i proceeded with the Windows Update restart, and now it is stuck half an hour at "Shutting down hyper-v virtual machine management service" Prior to restarting I did not observe any hard disk errors reported in the system event log; doubt it is a disk-related condition. Shall I force a hard reboot? UPDATE As per answer report, it eventually restarted itself.

• Git on Windows 7 expecting Linux? /dev/null not found error

  - by Klikini

  I have installed git (not GitHub) on Windows 7 x64 Home Premium, and I cannot get it to work. Opening Git Bash outputs the following: Welcome to Git (version 1.9.4-preview20140815) Run 'git help git' to display the help index. Run 'get help <command>' to display help for specific commands. sh.exe": /dev/null: No such file or directory sh.exe": /dev/null: No such file or directory sh.exe": /dev/null: No such file or directory sh.exe": /dev/null: No such file or directory sh.exe": /dev/null: No such file or directory sh.exe": /dev/null: No such file or directory Andy@ANDY-DELL ~ $ If I open the Git GUI, I get a this box: Title: git-gui: fatal error Content: fatal: open /dev/null or dup failed: No such file or directory Git Gui requires Git 1.5.0 or later. I also tried GitHub for Windows, but I got an internet connection error when attempting to clone a repo, even though my connection is fine. Is this possibly related? I have learned so far that /dev/null is the Linux version of the Windows NUL, but why is it trying to do this on Windows? Thanks in advance.

• SCCM Report to identify machines with 64-bit capable hardware

  - by GAThrawn

  Currently looking at deployment options for Windows 7. One of the questions we're looking into is 32 bit vs 63 bit. I'm trying to run a SCCM report against our estate to identify which machines are 64-bit capable (whether or not they're currently running a 64-bit OS). There seem to be a few resources out on the net for this (here, here and here) but none of them seem to work right on machines running 32-bit Windows XP. 32-bit XP machines seem to always report that they're running on 32-bit hardware. The query I'm currently running is: select sys.netbios_name0, sys.Operating_System_Name_and0 as OperatingSystem, case when pr.addresswidth0=64 then '64bit OS' when pr.addresswidth0=32 then '32bit OS' end as [Operating System Type], case when pr.DataWidth0=64 then '64bit Processor' when pr.DataWidth0=32 then '32bit Processor' end as [Processor Type], case when pr.addresswidth0=32 and pr.DataWidth0=64 then 'YES' end as [32-bit OS on x64 processor] from v_r_system sys join v_gs_processor pr on sys.resourceid=pr.resourceid I've also tried this, which reports all "Windows XP Professional" systems are on "X86-based PC", not x64 based even though a number of them definitely are: select OS.Caption0, CS.SystemType0, Count(*) from dbo.v_GS_COMPUTER_SYSTEM CS Left Outer Join dbo.v_GS_OPERATING_SYSTEM OS on CS.ResourceID = OS.ResourceId Group by OS.Caption0, CS.SystemType0 Order by OS.Caption0, CS.SystemType0 For instance we have a set of Dell Latitude E4200 laptops. Some of these are running 32-bit Windows XP SP3, some of them are running 32-bit Windows 7, some are running 64-bit Windows 7. All the laptops are identical, having come from the same order. Out of these the Windows 7 (32 and 64-bit) report that the hardware is 64-bit capable, and the Windows XP machines report that they're only 32-bit capable. Does anyone know if there's another value I can query to get the hardware's capabilities correctly on XP, or is there a hotfix that will get it reporting the correct info?

• SQL Server 2008 Cluster Installation - First network name always fails

  - by boflynn

  I'm testing failover clustering in Windows Server 2008 to host a SQL Server 2008 installation using this installation guide. My base cluster is installed and working properly, as well as clustering the DTC service. However, when it comes time to install SQL Server, my first attempt at installation always fails with the same message and seems to "taint" the network name. For example, with my previous cluster attempt, I was installing SQL Server as VSQL. After approximately 15 attempts of installation and trying to resolve the errors, e.g. changing domain accounts for SQL, setting SPNs, etc., I typoed the network name as VQSL and the installation worked. Similarly on my current cluster, I tried installing with the SQL service named PROD-C1-DB and got the same errors as last time until I tried changing the name to anything else, e.g. PROD-C1-DB1, SQL, TEST, etc., at which point the install works. It will even install to VSQL now. While testing, my install routine was: Run setup.exe from patched media, selecting appropriate options After the install fails, I'd chose "Remove node from a SQL Server failover cluster" and remove the single, failed, node Attempt to diagnose problem, inspect event logs, etc. Delete the computer account that was created for the SQL Service from Active Directory Delete the MSSQL10.MSSQLSERVER folder from the shared data drive The error message I receive from the SQL Server installer is: The following error has occurred: The cluster resource 'SQL Server' could not be brought online. Error: The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F) Along with hundreds of the following errors in the Application event log: [sqsrvres] checkODBCConnectError: sqlstate = 28000; native error = 4818; message = [Microsoft][SQL Server Native Client 10.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

• Bad disk performance on HP DL360 with Smarty Array P400i RAID controller

  - by sarge

  I have a HP DL360 server with 4x 146GB SAS disks and a Smart Array P400i RAID controller with 256MB cache. The disks are in RAID 5 (3 disks + 1 hot spare). The server is running VMware ESX 3i. The disk write performance is really bad. Here are some numbers: ns1:~# hdparm -tT /dev/sda /dev/sda: Timing cached reads: 3364 MB in 2.00 seconds = 1685.69 MB/sec Timing buffered disk reads: 18 MB in 3.79 seconds = 4.75 MB/sec ns1:~# time sh -c "dd if=/dev/zero of=ddfile bs=8k count=125000 && sync" 125000+0 records in 125000+0 records out 1024000000 bytes (1.0 GB) copied, 282.307 s, 3.6 MB/s real 4m52.003s user 0m2.160s sys 3m10.796s Compared to another server those number are terrible: Dell R200, 2x 500GB SATA disks, PERC raid controller (disks are mirrored). web4:~# hdparm -tT /dev/sda /dev/sda: Timing cached reads: 6584 MB in 2.00 seconds = 3297.79 MB/sec Timing buffered disk reads: 316 MB in 3.02 seconds = 104.79 MB/sec web4:~# time sh -c "dd if=/dev/zero of=ddfile bs=8k count=125000 && sync" 125000+0 records in 125000+0 records out 1024000000 bytes (1.0 GB) copied, 35.2919 s, 29.0 MB/s real 0m36.570s user 0m0.476s sys 0m32.298s The server isn't very loaded and the VMware Infrastructure Client performance monitor is showing 550KBps average read and 1208KBps average write for the last 30 minutes (highest write rate: 6.6MBps).

• Fix ACPI DSDT of Amilo Pa 1538

  - by kayahr

  I have a Fujitsu-Siemens Amilo Pa 1538 laptops and installed Ubuntu 10.04 on it (Kernel 2.6.32). Main problem is that the fans of the notebook are always on even when the temperature is low. Another problem is that the display brightness can not be adjusted. Since some years I use Dell laptops and never experienced any ACPI problems so I thought that it is no longer needed to fix ACPI tables but now I have this crap of a laptop and I think I have to do it. Unfortunately I need some help repairing the DSDT. The dsdt.dat and dsdt.dsl of the laptop can be found here: http://www.ailis.de/~k/permdata/20100420/dsdt/ Compiling the DSDT gives the following output: # iasl -sa dsdt.dsl Intel ACPI Component Architecture ASL Optimizing Compiler version 20090521 [Jun 30 2009] Copyright (C) 2000 - 2009 Intel Corporation Supports ACPI Specification Revision 3.0a dsdt.dsl 81: Method (\_WAK, 1, NotSerialized) Warning 1080 - ^ Reserved method must return a value (_WAK) dsdt.dsl 207: Method (_L10, 0, NotSerialized) Warning 1087 - ^ Not all control paths return a value (_L10) dsdt.dsl 2861: Method (NVIF, 3, NotSerialized) Warning 1087 - ^ Not all control paths return a value (NVIF) dsdt.dsl 4551: Store (\_SB.PCI0.LPC0.PMRD (0xFA), Local0) Warning 1099 - Statement is unreachable ^ ASL Input: dsdt.dsl - 4962 lines, 162828 bytes, 2300 keywords AML Output: dsdt.aml - 17627 bytes, 591 named objects, 1709 executable opcodes Compilation complete. 0 Errors, 4 Warnings, 0 Remarks, 519 Optimizations Anyone here with DSDT experience who can help me fixing the DSDT?

• Ideal Bacula appliance?

  - by Ricket

  I'm an intern at a small company and we (the IT department of two) manage <100 client computers and a handful of servers. Currently we're using a company's appliance to handle backup; it does a small backup every night and a full backup every weekend, and a guy comes on Wednesday to take an offsite backup drive (and gives back last week's drive to swap with it). Lately this system, mainly the appliance, has been having problems, so we are looking for an alternative. I'm researching other companies but also looking into what we might expect from trying to do this ourselves. There will undoubtedly be a large learning curve, but hey, that's what serverfault is for, right? :) So anyway I was looking at Bacula. Feature list sounds great, documentation is plentiful, but it's only software. So my question is, what is the ideal backup server to run the Bacula server software on? And not only the server but other related appliances. Our current backup appliance uses only hard drives, not tape drives. It has several plugged into it at one time, in hotswap bays on the front of the machine. I couldn't help but notice though, it's hardly more than Windows XP with hard drive bays, a PCI eSATA card (which connects to another appliance extension piece with 2 more bays), and their software. Since the company will take back their appliance if/when we cancel with them, where can I go to configure a server with these kinds of things? Maybe I'm being naive, I'm sure Dell (and any other computer company) sells them in the small business section of their website, but I wanted to make sure that there's not some other more recommended place that other companies are getting their hardware from, and that I don't need anything special for Bacula.

• How to find virtualization performance bottlenecks?

  - by Martin

  We have recently started moving our C++ build server(s) from real machines into VMs. (MS Hyper-V) We have some performance issues that I've currently no idea how to address. We have: Test-Box - this is a piece of desktop workstation hardware my co-worker used to set up the VM before we moved it to the actual server hardware Srv-Box - this is the server hardware Test-Box-Real - This is Windows running directly on the Test-Box HW Test-Box-VM - This is Windows in a Hyper-V VM on the Test-Box HW Srv-Box-Real- This is Server2008R2 running on the Srv-Box HW. Srv-Box-VM- This is Windows running in a Hyper-V VM on the Srv-Box HW, i.e. on Srv-Box-Real. Now, the problem is that we compared Build times between Test-Box-Real and Test-Box-VM and they were basically equal (within about 2%). Then we moved the VM to the Srv-Box machine and what we saw there is that we have a significant performance degradation between Srv-Box-Real and Srv-Box-VM, that is, where we saw no differences on the Test HW we now do see major differences in performance on the actual Server HW. (Builds about ~~ 50% slower inside the VM.) I should add that both the Test-Box and the Srv-Box are only running this one single VM and doing nothing else. I should also note that the "Real" OS is Win2008R2(64bit) and the VM hosted OS is Wind2003R2(32bit). Hardware specs: Srv-Box: Intel XEON E5640 @ 2.67Ghz (This means 8 cores with hyperthreading on the Real system and "only" 4 cores on the VM, since Hyper-V doesn't allow for hyperthreading, but number of cores doesn't seem to explain the problem here.) 16GB RAM (we have 4GB assigned to the VM) Virtual DELL RAID 1 (2x 450GB HUS156045VLS600 Hitachi 15k SAS drives) Test-Box: Intel XEON E31245 @ 3.3GHz 16GB RAM WD VelociRaptor 600GB 10k RPM SATA Note again that I'm only concerned with the differences between Srv-Box-Real and Srv-Box-VM (high) vs. the differences seen btw. Test-Box-Real and Test-Box-VM (low). Why would one machine have parity when comparing VM vs Real performance and the other (server grade HW no less) would have a large disparity? (Both being XEON CPUs ...)

• Remote Desktop Connection Only Works One Way

  - by advocate

  I can't get my desktop to connect to my laptop through remote desktop connection. Unfortunately I can only get my laptop to connect to my desktop (quite useless). Desktop: Windows 7 Ultimate 64 Bit SP1 Windows firewall is off for all 3 profiles (domain / private / public) Remote desktop connection is installed and set to allow all connections Under running services is: Running Remote Desktop Configuration Running Remote Desktop Services Running Remote Desktop Services UserMode Port Redirector Running Remote Procedure Call (RPC) Stopped Remote Access Auto Connection Manager Stopped Remote Access Connection Manager Stopped Remote Procedure Call (RPC) Locator Stopped Remote Registry Stopped Routing and Remote Access Stopped Windows Remote Management (WS-Management) Laptop: Windows 7 Home Premium 64 Bit SP1 Windows firewall is off for all3 profiles (domain / private / public) Remote desktop connection is installed and set to 'Allow Remote Assistance connections to this computer' Under running services is: Running Remote Procedure Call (RPC) Stopped Remote Access Auto Connection Manager Stopped Remote Access Connection Manager Stopped Remote Desktop Configuration Stopped Remote Desktop Services Stopped Remote Procedure Call (RPC) Locator Stopped Remote Registry Stopped Routing and Remote Access Stopped Windows Remote Management (WS-Management) It should be noted that the Laptop that I'm trying to connect to is an Alienware and might be running some wonky Dell settings. Also, the settings are slightly different for remote desktop connection as it's a Home edition of Windows and not Ultimate like my desktop. Finally, both computers are on the same Homegroup so that RDC can be accessed by one click through the network section of Windows. They're also on the same workgroup, MSHOME, just to see if that helps.

• Windows Server 2008 Stops Responding (Hyper-V Role Enabled)

  - by blackf0rk

  The machine is a brand new Dell Precision m6500, Core i5, 8GB RAM. Windows Server 2008 R2 (fully patched) with Hyper-V Role Enabled. Virtualization options in the BIOS are ON, SpeedStep is OFF, couldn't find C1E option in the BIOS to turn it off (I also got the impression that SpeedStep is C1E, but the Intel Product site lists them as separate "features." shrug) The server stops responding without any apparent reason. I've tried testing in multiple scenarios, all of which result in a crash at seemingly random times: With the Server sitting idle, no apps running. Server sitting idle with a Virtual Machine running. Using a BurnInTest application There's no blue screen. It doesn't restart. The screen just sits there. The keyboard backlight still responds and comes on with input, but nothing on the screen changes. There are no errors in the error log. I have to hold down the power button to turn it off. Doing memory tests on bootup results in no errors with the memory. I have a second identical system and the same thing happens there too. I've dual-booted into Windows 7 Profession x64 on this system with no problems. Further testing has shown that the issue is definitely related to Windows Server 2008 R2 and Hyper-V as it appears the crashing does not happen when the services are not running. I've installed all hotfixes relating to this issue (that I could find): 975530, 979444, 979491, 976427 System is still crashing without response.

• Understanding Linux SCSI queue depths

  - by Troels Arvin

  I'm experimenting with the effects of different SCSI queue depth values on a Dell server running CentOS Linux 5.4 (x86_64). The server has two QLogic QLE2560 FC HBAs connected via multipathing to a storage system. The storage system has allocated two LUNs to the server, each connected through four paths in an active-active-active-active round-robin configuration. All in all, the two LUNs exist as eight /dev/sdX devices, represented by two devices in /dev/mpath. I currently adjust the queue depth values in /etc/modprobe.conf and check the result (after rebooting) by looking in the seventh column of /proc/scsi/sg/devices. Two questions related to that: Is there a way to adjust queue depths without rebooting or unloading the qla2xxx kernel module? E.g., can I echo a new queue depth value into some /proc or /sys-like file to update the queue depth? If I set the queue depth to 128, is that 128 in total for all devices handled by the qla2xxx module?, or 128 for each HBA? (256 in total), or 128 for each of the eight /dev/sdX devices (1024 in toal)?, or 128 for each of the two /dev/mpath/... devices (256 in total)? This is important for me to know so that my server doesn't flood the storage system, affecting other servers connected to it.

• System Information (msinfo32.exe) Can't Collect Information

  - by ptanne

  I have Windows XP Pro, service pack 1, IE 6 and 32GB of free space, 75GB total. I have had nothing but trouble after trying to install service pack 2 even though I used System Restore. The installation was incomplete and my computer has never been the same. I attempted to install sp2 four or five times and sp3 once, always with the same result. I've tried reinstalling XP Pro but that didn't fix the problem. My XP Pro disk now has a scratch on it and refuses to work. Dell would not replace it stating that my computer was out of warranty. I'm currently trying Reimage which is supposed to return a computer to the original configuration and replace missing or damaged files. Believe it or not, Ripley, it stops in the middle of the operation and, so far, the Reimage techs haven't been able to figure out why. Of the many problems that I still have is that System Information can't collect information. The Help and Support sections that display system info also don't work. Is there some way that I can fix this? I can't afford to throw my computer away, yet. Thank you for listening, Pam Galvin

• ZFS + FreeBSD + virtualbox

  - by John

  Hi, I'm configuring a FreeBSD server hosting virtualbox serving half dozen mission critical busy mail servers. I just learned ZFS, I'm quite attracted, but have a few questions: what is the CPU overhead of ZFS? I googled and found little (or no) benchmark for that. from what I learned, when ZFS updates files, it keeps the old file as snapshot, and write the updated part for the new version. However that would mean for each snapshot it keeps that require significant storage overhead. How much is this storage overhead? For example, suppose I have 2TB usable space, how much space can actually be used for the latest version of files one year later? is FreeBSD with ZFS hosting virtualbox serving half dozen busy guest mission critical mail servers a reasonable combination? Anything particular to be careful with? And can I still choose ZFS for the guest OSs? This is because I may build another identical such box for redundancy, and will need to do some mirroring between each pair of the guest systems across the boxes. I'm trying to configure a Dell R710 for this. From what I learned, I shouldn't choose any RAID at all, is that true? In that case, are the drives still arrive hot swappable? this may sounds a bit pathetic, but since I have no experience with ZFS at all, and this is a mission critical server, so just ask just in case: I'm choosing twin Intel L5630 processors, and 6 x 600GB 15K RPM Serial-Attach SCSI drives. If I need more space in the future, I would just hot swap some drivers with larger capacity to expand the storage. There is no problem with these, right?

• Recommended motherboard with hardware raid for Linux

  - by luison

  Hi. We want to setup an internal office server for testing jobs (LAMP), email and samba. Only about 5-10 users. We are also considering starting to virtualize, initially by a base Ubuntu Server with Xen or VMWare Open Source server. Our current system runs with a Linux Raid which has worked great but it's always been complicated to recover the boot sector when one the drives fail and therefore I would prefer using now a hardware raid instead, but ideally with some kind of software monitoring. For this reason and considering we don't want to spend a fortune a I would appreciate any comments on the following options. Motherboard with RAID with linux support... which could you recommend. Motherboard + Hardware Raid card... Adaptec does not seem to have great Linux suppport. 3Ware seems to have a tc soft controller which we've used on a hosting company, but hard to find here in Spain. HP Proliant type basic server, which? Dell Small Servers... any good for Linux? Thanks in advance for any feedback.

• Windows 7 AIK help

  - by microchasm

  I've just got in a few Windows 7 (64, Windows 7 Professional) machines, and I'm trying to get the AIK 2010 working. I've set up one of the machines, and installed AIK and MDT on it. I've followed the directions at http://technet.microsoft.com/en-us/library/dd349348%28WS.10%29.aspx about 3 times now, and also tried the built-in .chm help files that came with AIK. In AIK I grab the install.wim image off the OEM cd, at which point it asks me which version (I select Professional). I follow the rest of the instructions creating a new Autounattend answer file, and fill in the various bits and pieces according the the step-by-step guides. I verify the Answer file (No warnings or errors), save it, and copy it onto a USB drive. I go to another machine, insert it's OEM Win7 Disk, and power on. I've set BIOS to boot from CD, so it goes directly into the installation. Once The files are loaded, and Setup starts, it immediately asks which version to install (Home basic, Home Premium, Professiona, Ultimate). Ugh, I thought it was supposed to be an automated install, and that selecting the Version when opening the .wim file would answer this question. I looked for an option to set which version to be installed on the net, in the help, and in AIK itself; to no avail. Anyway, just for laughs I select Professional,and hit continue. It copies files for about 10 seconds, then fails with the following error: "Setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more information. [OK]". Clicking OK reboots the box, and obviously there are no log files because the OS isn't installed. It is a Dell Optiplex 380 , Intel Core Duo 2.93 GHzl 4 GB RAM, 64 Bit. Any help would be REALLY appreciated.

Bad Blocks Exist: Yes How could there be bad blocks in a Virtual Drive, which is in optimal state and no disk is broken or even with a single error? I tried "Consistency Check", but it finished successfully and the errors are still in dmesg. Could Someone help me to figure it out what is wrong with my raid?

• Can VMWare Server 2.0 be useful in Production for easing backups?

  - by Keith Sirmons

  Howdy, Let's run this idea by the group here. I am thinking about using VMWare Server in production to host a 2008 Domain Controller with DHCP and DNS, a 2008 member server with WSUS, some virus software, and other "management" utilities a second 2008 member server with SQL, IIS, and File Shares for a medium business of 50-100 desktops. The reason I am leaning toward Server vs ESXi is for backup purposes. Using ESXi, if I want to backup the VM's, I would need a second server in the office with enough storage availability to hold a copy of the vmdks. I am wondering if putting this virtual environment on top of a basic 2008 server install will allow for easier backups to both tape and/or to offsite storage using JungleDisk. Can a snapshot be triggered easily via a scheduled job? I know this doesn't necessarily handle file level restores, but I want to make sure in a DR situation, we can restore production servers quickly. Does this concept hold water? Would a very minimum install of the 2008 Host remove too many resources from the actual production machines? This would be a new Dell 410 server with 12 GB ram and (6) 600 GB 15K in a RAID 6, Dual Intel Xeon 2.26GHz procs.

• Windows 7 install detects SSD but doesn't list it to install to

  - by Mohamed Meligy

  I'm having quite a weird problem when trying to install Windows 7 SP1 on a new Corsair Force Series 3 SSD to replace a failing HDD in my wife's laptop. When I boot to Windows install, it shows that I have no disks to install to, and tells me to find it a driver to any custom disks I may have. When I go to repair option on the first install window, and then open command prompt Window, I can see the disk using diskpart, and can partition it and format partitions, and then later access them from command prompt and copy files to them. After creating partitions, clicking the "browse" button in Windows install screen that shows no disks available to install Windows to, does show the partitions created by diskpart! So, it does detect the disk and partitions, but refuses to list them as options to install to. People on the Interwebs seem to suggest that just running diskpart "clean" solved the issue for most people, just creating an "active" "primary" partition is al most tutorials suggest. Both got me only as far as described above. The BIOS doesn't have RAID option, changing between "ATA" and "AHCI" (the only available options) didn't make any difference. Might be worth mentioning that this is on a laptop that has Sata III controller for main drive (which I connected the Sata3 SSD to), and Sata II for DVD (which I used for Windows install media). That's what googling brings at least (DELL XPS 15 L502). Any ideas? . Update: The SSD is 460 GB. I tried setting it all as one partition and creating 70-90 GB partition as well (NTFS). More importantly, Windows doesn't list the partition as one it cannot install to (which it does with disks in general when they are small for example). What happens here is different. It doesn't list anything at all. It shows empty list of drives.
