• IE10 does not open .pdf

  - by user203298

  I can't open any PDFs in IE10 on Win7 64bit. I've tested with PDFs from Intranet / Internet / local file system, http and https. I've tested installing/uninstalling Acrobat Reader 11.0.03 and the Nitro PDF Reader. I've also tried enabling/disabling the Tools Internet Options Advanced Security Do not save encrypted pages to disk option. In Google Chrome PDFs are opened in the Acrobat Reader Plugin, but in IE10 the only thing I always get is a small cross in the top left corner of the browser. Can anybody help me?

• Folder cannot be deleted

  - by Aaron

  I am using Windows XP Home Edition. When I try to delete a folder I have named cygwin. When I try to delete it or any file or folder within it, there is a long pause, and then an error pops up, saying: Cannot delete Cygwin: Access is denied. Make sure the disk is not full or read-write protected and that the file is not currently in use. I have tried deleting the folder and the files it contains with FileAssassin, and unlocking it with LockHunter. Neither report any errors unless I try to have them delete the file or folder, then I get an error message saying Access Denied. I have rebooted into Safe Mode to change the ownership, but I get Access Denied when I click OK or Apply. How can I delete this folder?

• Putting our OLTP and OLAP services on the same cluster

  - by Dynamo

  We're currently in a bit of a debate about what to do with our scattered SQL environment. We are setting up a cluster for our data warehouses for sure and are now in the process of deciding if our OLTP databases should go on the same one. The cluster will be active/active with database services running on one node and reporting and analytical services on the other node. From a technical standpoint I don't see an issue here. With the services being run on different nodes they shouldn't compete too heavily for resources. The only physical resource that may be an issue would be the shared disk space. Our environment is also quite small. Our biggest OLAP database at the moment is only about 40GB and our OLTP are all under 10GB. I see a potential political issue here as different groups are involved but I'm just strictly wondering if there would be any major technical issues that could arise from this setup.

• misaligned raid partition in Ubuntu 10.04

  - by Linux Jedi

  I attached two identical hard drives to my linux machine. Then using gparted I formated the first 1024 mb at the beginning of each drive as linux swap space. Then I went into system-administration-disk utility. In there I went to file-create-RAID array. I selected the remaining space in each of the two identical hard drives and created a striped raid array. After the array was created, a warning message appeared. It said "The partition is misaligned by 522240 bytes. This may result in very poor performance. Repartitioning is suggested." What do I do now? As far as I can tell, the partitions are identical.

• team foundation server 2010 installation from DVD - I get agent installation instead!

  - by Avi

  GRRRRRRRRRRRR!(#Y%)@#!! They bragged they now have a very easy installation! I don't get it. I entered the MSDN "Disk 5000: Developer Tools" DVD, opened default.htm, clicked on the "Visual Studio Team Foundation Server 2010" link. The VSTFS2010 folder open. I click autorun.exe. And then I get "Microsoft Visual Studio Agents 2010 Setup". I don't get it. Why "agents"? I wanted to instal a server!

• Installing php(suexec) for Apache

  I've got Apache installed and running but how do i install and run PHP as fastcgi so it runs as its own user? here is my apache config: ./configure --prefix=/usr/local/apache2 --enable-rewrite=shared --enable-so --enable-suexec --disable-asis --disable-autoindex --enable-cache --enable-deflate --enable-disk-cache --enable-expires --enable-file-cache --enable-mem-cache --enable-ssl --enable-vhost-alias --with-mpm=prefork --with-port=8080 here is my php config: ./configure prefix=/usr/local/php --without-pear --enable-safe-mode --enable-magic-quotes --with-apxs2=/usr/local/apache2/bin/apxs --disable-cli --disable-cgi --enable-force-cgi-redirect --enable-fastcgi --with-mysql --with-gd --with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib --with-freetype-dir=/usr/lib --enable-calendar --with-curl --enable-mbstring --with-mcrypt

• Shrinking physical volumes in LVM on a Linux Guest in ESXi 5.0

  - by Stew

  The problem: Linux guest (OpenSuse 12.1), with multiple virtual disks attached. 3 disks are in a logical volume, two of which are exactly 2TB. None of the disks are independent, and due to the backup software we use, cannot be independent. When the two 2TB virtual disks are "dependent", the snapshot fails stating that the file is too large for the datastore. When I put those two disks in independent mode, snapshots work fine (the other disk is 1.8TB). I have therefore concluded that even shrinking the two physical disks by 100GB should solve the problem, however I am having trouble conceptualizing how to go about getting those disks smaller without breaking the LVM entirely. The actual LV has 1.3TB free, so there is plenty of space to shrink with. What I need to accomplish: Deallocate 100GB from the two, 2TB virtual disks within the linux guest. Shrink the two virtual disks by 100GB within vsphere (not as complicated). Are there any vsphere/LVM gurus that can give me a clue?

• Search Files (Preferably with index) on Windows 2000 Server

  - by ThinkBohemian

  I have many files on a windows server 2000 machine that is setup to act as a networked disk drive, is there anyway I can index the files and make that index available as a search to more people than just me? Bonus if the index can look inside of documents such as readme.txt? If there is no easy way to do this globaly (for all users) Is there a way I could generate and store an index locally on my computer? If this is the wrong place to ask this question, any advice on community more suited?

• Reinstall Windows on mass computers

  - by user791022

  At work there are about 40 DELL PC's - half of them are Windows Vista and other half are Windows 7. Some of the DELL PC's are 220s and 230s model. If I want to re-install Windows then I can use a Recovery/Recovery disk on any Dell PC's (220s or 230s). It take too long to complete the setup, for example - after re installing the Windows then I need to install the drivers, update windows, install IE9, create default users account and so on. It take about 3 hour to complete setup! I am looking for a solution Where I can create an Image of windows (with driver and completed setup) and then I use same Image it on any PC's at work? If one of the PC need reinstalling - I would like to reinstall via network (LAN) by grabbing the Image? Is there something that before booting into windows - computer check something via network which can download the Image?

• Common filesystem for servers behind a rackspace load balancer

  - by thanos panousis

  Our PHP application consists of a single web server that will receive files from clients and perform a CPU-intensive analysis on them. Right now, analysis of a single user upload can take 3sec to conclude and take 100% CPU. This makes our system capacity amount to 1/3 requests per second. My team's requirement is to increase capacity without a lot of code reengineering. A possible solution would be to set up a load balancer in front of multiple servers running the same app, connecting to a common DB. The problem is that the analysis outputs files on disk. A load balancer would increase capacity, but then files won't be available between servers so consequent client requests may fail. We are hosted on Rackspace, is there a way to configure some sort of "common" storage for all servers, without having to rewrite our file persistance code? Current code relies on simple fopens etc. What are our options?

• High Lock Wait ratio in MySQL

  - by FunkyChicken

  on my site I log every pageview (date,ip,referrer,page,etc) in a simple mysql table. This table gets very little selects (3 per minute), but a lot of inserts. (about 100 per second) Today I changed this table from an InnoDB table to a MEMORY table, this made sense to me to prevent unnecessary hard disk IO. I also prune this table once per minute, to make sure it never get's too big. -- Performance wise, things are running fine. But I noticed that while running tuning-primer, that my Current Lock Wait ratio is quite high. Current Lock Wait ratio = 1 : 561 My question: Should I worry about this Lock Wait Ratio? And is there something I can change in my my.cnf to improve things so that the lock wait ratio isn't so high?

• Linux web server shared hosting file errors

  - by dfilkovi

  I'm using a shared hosting to host my website and have some problems with files from time to time. First, one of my file (php) was missing a part of code (nothing to do with hackers just a random piece of code was missing), then after some time a value inside a mysql table was also missing a part, then a whole table column disappeared, after that a whole file on my site disappeared and lastly again some code from a file disappeared, my hosting service says it has nothing to do with them, but this is stupid, how can this happen, no hacker attack could do such a thing, I believe it's some kind of a disk corruption or bad backup. Anyone have any ideas?

• Proper way to partition filesystem with Xen

  - by luckytaxi

  I'm coming from a vmware environment, wanting to play with Xen. I have a server with 2 x 500G SATA drives (no hardware RAID available, have to use software-based RAID1). My partitions are all RAID1 except for swap. I left a little over 400G for my VMs and I would like to use LVM for the disk images. For domU's swap, should I allocate that from the 400G or should that be coming from dom0's partition? I asked because I've seen numerous config options that shows either or.

• Windows 7 blocks network access to network-installed apps

  - by VokinLoksar

  Windows 2008 R2 domain. Users, running Windows 7 Enterprise, are trying to run some software from a network share. Specifically, I've tested this with MATLAB and PuTTY. When starting, MATLAB has to contact a licensing server to get its license. This action fails for regular users when they start MATLAB from the network share. However, if they copy the installation directory to a local disk everything works fine. Running MATLAB as an admin user from the network share also works. Same story with PuTTY. If the executable is launched from the share, regular users cannot connect to any servers. Something is blocking network communications for programs that are launched from a network drive. Here's the only other mention I could find of the same problem: https://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/4504b192-0bc0-4402-8e00-a936ea7e6dff It's not the Windows firewall or the IE security settings. Does anyone have any clue as to what this is?

• Does Intel Smart Response provide any statistics on the cache usage?

  - by Tom Seddon

  I've set up my Z68-based Core i7 PC with a 60GB SSD dedicated as a Smart Response cache drive. Is there any way I can get any statistics out of it? It would be nice to have some information on how much cache space is actually being used, maybe how much of it was actually accessed recently, and how many reads in general are coming from the SSD rather than from the mechanical disk. These statistics might help to quickly provide some evidence for or against the use of Smart Response, without my having to reinstall Windows on the SSD (etc.) to find out. The Windows ReadyBoost feature has some performance counters you can access via the Windows 7 perfmon tool, for example, which is the kind of thing I'm hoping is somehow available. Smart Response provides no perfmon counters, though, and the Intel Rapid Storage Utility tells you pretty much nothing except that Smart Response is switched on.

• Expanding RAID 1 array size (Adaptec 1420SA controller)

  - by cincura.net

  I have an Adaptec 1420SA controller in server and RAID 1 array created. The old disks slowly started to report S.M.A.R.T errors so I replaced first one, rebuild array and then other one and rebuild the array again. But the new drives are bigger, so I'd like to expand the array to use full disk capacity. Is it somehow possible? In the Adaptec configuration utility, after POST, I didn't found anything that could do it. I still have the old drives, if it helps. The array is used for system (Windows 2008 R2 SP1) booting. Thanks.

• How to determine non-movable files in Windows 7?

  - by David

  Is there a way to determine which unmovable files are preventing Shrink Volume from releasing the full potential free space? Background: I have a 90 GB partition with Windows 7 on it, and 60 GB free space. I want to shrink it down to about 40 GB, and use the reclaimed 50 GB for a separate data partition. The Shrink Volume tool in Disk Management is only willing to give me 8 GB back. My understanding is that this is because of immovable files. I've followed the instructions found here, which involved disabling hibernation, pagefile, system restore, kernal dump, making sure all related files were deleted, and defrag'ing. I have successfully followed those same instructions before on this same drive, and partitoned the original 150 GB space into 90 GB and 60 GB, but I'm not so lucky this time.

• Very slow Windows 7 on Thinkpad T61

  - by bogdanf

  I have a very strange problem with my fresh install of Windows 7 Profesional, 64bits on my Lenovo Thinkpad T61 : The overal performance is very slow, the disk is constantly spinning, even without any program running (after boot, no other programs installed). The boot process is very slow itself (4-5 minutes). I mention that the laptop was fine on XP until the upgrade. Thanks ! Additional info (as requested by the comments) : 2GB RAM Yes, I added all the manufacturer (Lenovo) drivers and updates (using the utility provided by Lenovo) Tried with both 32 and 64 bits editions. The 32 bits one is performing a little better, but not very usable either. The hdd has enough space (20 GB or so) The problem is still present on a fresh install, so no recycle bin emptying or unistall programs (there aren't any except plain 7) would help. I'm not a newbie, so no obvious causes are left unchecked

• Taking an image backup of an entire server?

  - by WarDoGG

  I am currently using a dedicated server for my hosting needs. However, the costs are too high and I would like to suspend everything until I work out my business strategy again. Is there a way I can take a complete backup of the filesystem and run it in VMWare ? I cannot just copy the entire filesystem because there are lots of tools installed and tight changes to the server configuration files I myself dont know about (by the developers), but I need a snapshot of the entire disk image along with processes installed and everything is as is because for development needs, I need to work on this copy in VMWare or VirtualBox etc. Is it possible for me to take a full image copy ? How do I do it ?

• Strange issue with 64 bit OS

  - by Sherwin Flight

  So I own two versions of Windows 7, one is 32 bit, the other is 64. The 64 bit version came with my new desktop, and the 32 bit version came with my Laptop. I was doing a clean install of my laptop, and the install went smooth, Windows is up and running! However, after installing it I realized that I accidentally used the 64 bit installation disk instead of the 32 bit version. I confirmed this in the System Information screen, it says: System type: 64-bit Operating System As far as I knew this laptop was only a 32 bit machine. My understanding is that a 64 bit OS would NOT run on 32 bit architecture. Am I correct with this assumption? If this was a 32 bit laptop is there any way a 64 bit OS would even run at all on it?

• Windows Azure virtual machine credentials

  - by Georges

  I have created a Windows Server virtual machine, and this also automatically created a disk (VHD). Then I removed the vm, and I created a new vm from the same vhd: in this process I wasn't asked to supply any credentials. I am not able anymore to login (with rdp) to the new VM, the credentials that I supplied when creating the first machine don't work anymore. Any ideas why this happens? What credentials should I use? Thanks a lot in advance.

• How To Cancel Pending Windows 7 Updates

  - by Itai

  How To Cancel Pending Windows 7 Updates? The key is pending. The shutdown button has the windows update symbol meaning that there are updates that were selected to be installed which were download and will be installed upon shutdown. The only thing is that my machine will no longer boot if I let it install those updates! They are incompatible with a driver needed in the system and I did not found out until too late. The system admin used a recovery disk to get back to the previous restore point, only the updates are now pending, so I need to cancel those before the machine shutdowns next.

• Is paravirtualization evil?

  - by Daniel

  I have an VMWare ESX Server v3.5 with a few virtualized Debian Lenny VMs (kernel 2.6.22 with vmi) running Apache Tomcat 5.5. I enabled paravirtualization, and Disk IO increased from about 240MB/s to 380MB/s, making me a happy admin. The problem now is that my apache tomcat becomes deadlocked during startup, running with 200% CPU (I have 2 CPUS assigned to the VM), and don't know how to get both: A stable system and a fast system. I somewhere heared that paravirtualization is legacy anyway and won't be available on newer ESX servers. Is there a replacement for this seemingly performance-improving option, or is it discontinued becauses it is just unstable? What is the state of paravirtualization? Should I ignore it completely? Thanks for all answers in advance.

• Setup local EC2 style cloud?

  - by John Kramlich

  I was recently given 3 dual opteron 2400 servers with 4GB of RAM and 120GB hard drives. I am interested in setting up something similar to Amazon's EC2 for my own personal web development use. Basically, I would like to spin up instances from an ISO or other disk images and have them available to test and develop software. Are there open source solutions I can use to accomplish this? I am assuming one of the machines will need to act as a controller of some sort for the other two. I use Sun's VirtualBox on my local development machine to virtualize various versions of Microsoft Windows. However, I'm not sure if that's the best tool for what I am trying to achieve. I apologize in advance if this question is to vague to get meaningful responses. I am new to cloud computing and fairly new at server administration.
