• Windows + Jolicloud crash!

  - by SystmHck

  My girlfriend's Acer Aspire One netbook just crashed running Windows XP. It crashes at the boot process, displays the blue screen for a second and then reboots. I also installed Jolicloud through Jolicloud Express but I am not able to boot it either. I suspect it's a virus... When running a Ubuntu live session from a pendrive it seems like the Acer partition is corrupted. In a partition program it says to run chkdsk in Windows to fix it. I have used Ubuntu for a while but I am not an expert so I wanted to ask: How do I restore my NTFS damaged partition?

• IP packet proxy solutions? Riverbed alternative

  - by Ruvan

  I have stumbled upon Riverbed.com's products which basically has the capability to hash chunks of IP data and subsequently store them to disk. I'm looking for an open source / cheaper alternative. WANProxy is the exact equivalent except that it only keeps data in-memory and can't store the data to disk which is a requirement for our solution. I'm basically looking for a proxy which not only looks at the files (filenames) but the data itself being transmitted at the packet level. Anyone? Thanks!

• iSCSI drives suddenly inaccessible or corrupted

  - by Hammer1

  I have two NAS (Seagate Black Armors) connected to our network through iSCSI to a Dell Optiplex 760 running 32-bit Windows 7 and Windows iSCSI Initiator. For some unknown reason within the last week both are reportedly inaccessible and/or corrupt (that is the error message generated when I attempt to open the on the iSCSI computer). However, connecting to either of them via direct IP goes off without a hitch. I've tried Error checking but received "The disk check could not be performed because Windows could not access the disk." I've tried System Recover to a date almost two weeks back thinking Windows update may have caused the issue but there is no change. Anyone have an explanation and/or a solution to get them reconnected? Thanks.

• How create a virtual network for practice?

  - by light

  I need to organize a virtual network for practice with Windows Server 2008 and several workstations with Windows OS. To make it all I only have a laptop with Dual-Core 2.10Ghz, 3 GB RAM, 50 GB free space and Windows 7 on it. Also I have external USB 3.0 hard-drive with 250GB free space and flash disk with 8GB space. What can you suggest? Because I have limited resources, I think to install ESXi 5.1 on the main disk of my laptop as second OS, with installed Windows 7. I have no idea will it work or not, but after that I want to try to create hosts using availible space on external hard-drive. Is it possible?

• Why does MS-DOS tells me I need extended memory and thinks a file is read-only? [closed]

  - by Jake Inc.

  I am running a .COM file on a MS-DOS 6.22 boot USB drive When I run it on my laptop the program works fine but when I run it on my desktop I get error 40 not enough extended memory. When I go to the memory tab in GUI I try to switch none to auto, but I get the error "This file might be read-only". It's not read-only, when I put it on my desktop I change the settings and the new settings are in a .pif I can't run .pif in MS-DOs so I need to Change the .exe not create a .pif. Change the amount of extended memory all files have on my MS-DOS. On my laptop there is no memory tab, the only real difference is my laptop is x64. Thanks for helping but I think teh x64 bit has nothing to do with it I dont eve nthink iits in 64 bit mode because Im using a boot USB. What i need to is listed above, thanks for helping.

• Syncing 1TB+ to a iSCSI device, software needed

  - by mojah

  Hi, I need to sync a local disk to a iSCSI mount on Windows (server 2003), and I'm struggling to find software that's capable of doing so in a reasonable timeframe. Notes on the current 1TB disk: - 800GB currently in use - Contains a folder with several hundred thousand subfolders, which in turn have several thousand files, ... So I'm trying to find a piece of software that can handle such large filelists, and give me a good timeframe on when this will be copied. I've tried DeltaCopy (the rSync GUI client for Windows), but it's intolerably slow and doesn't provide me with a good estimate time remaining. DeltaCopy: http://www.aboutmyip.com/AboutMyXApp/DeltaCopy.jsp Does anyone know alternative software for Windows, that would do this well?

• Keyboard no longer works when entering BIOS

  - by Tommy

  I am trying to boot from USB so I can install a couple different Linux distros. I can enter the BIOS, but as soon as I enter the BIOS the keyboard lights switch off (Num Lock and Caps Lock) and I cannot use the keyboard to do anything in the BIOS or even exit or restart the PC using Ctrl+Alt+Del or do anything at all with the keyboard. But as soon as I boot back into Windows, everything is fine... I've never had this problem before and some Googling hasn't helped. I've tried using a few other keyboards and simply unplugging/replugging the keyboards, but it didn't work. Is there anything I can do in Windows to maybe find out why the keyboard isn't working in the BIOS screen? In the Device Manager, all the drivers are up to date and there are no conflicts.

• VMWare Input/Output error on ubuntu host Win7 guest

  - by CShipley

  I am running ubuntu 10.10 as my host with Windows 7 as the guest. About a couple weeks ago I started getting error pop-ups from vmware reporting inability to read or write to a particular file. On futher investigation, I've noticed that I cannot copy that particular file from the linux command line even as root. I get the same input/output error. The SMART utility tells me I have 69 bad sectors on the disk (it is 1 TB) So my question is 1) How do I tell if that HD is going bad? 2) How can I move the VM files to a different part of the disk if I get read/write errors when I try to copy?

• Booting an EXT4 image file from GRUB2

  - by sjjg

  My friend needed a fast HDD so I gave her my small 64GB SDD. This SSD had my Linux install on it. I used dd to make an image of the partition (boot, root and home on one partition). This partition is now sitting on a traditional 500GB EXT4 formatted drive. Is there any way I can get GRUB to just boot using this .img file I have? I'm not getting my SSD back and I can't be bothered to go through the hassle of setting up my Linux install from scratch. I have come across loopback support in GRUB for ISO images. Does this support EXT4 also? I don't seem to be able to find anything specific and don't want to trash anything. Cheers.

• BackupPC back-up has not been finished in 12 hours(!)

  - by chronoz

  I installed BackupPC toda on a server and set it to do a back-up 12 hours ago... while it's been backing up since, it seems very very slow and it's not completed yet. It's just backing up a testserver with a total disk usage of 1.8GB. What could cause the back-up process to be so slow? rsnapshot always worked wonderfully fast, but I want to improve my back-up solution. df shows that the size on the back-up disk is actually still increasing.

• Rebuild mdadm RAID5 array with fewer disks

  - by drjeep

  I have a 4 disk RAID5 array, one of which is starting to fail according to smartd. However, since I'm using less than half the space on /dev/md0, I'd like to rebuild the array without the failing disk. The closest scenario I've been able to find online has been this post, however it contains bits that don't apply to me (LVM volumes) and also doesn't explain how I go about resizing the partition after I'm done. Please note I have backups of important data, but I'd like to avoid rebuilding the array from scratch if possible.

• JBoss 4.2.3 Won't Start

  - by Thody

  Hi, I'm trying to start a new installation of JBoss 4.2.3, and it's getting as far as "INFO [Server] Core system initialized", then hanging for several minutes. There is a Java process running, but only at ~35%. Also, looking at the boot.log, there are no entries after ~1s after starting the boot. Any ideas what might be up? Update: After about 10 minutes, I got a handful of garbage collection warnings: GC Warning: Repeated allocation of very large block (appr. size 512000): May lead to memory leak and poor performance.

• Will readyboost speed up a secondary partion or harddrive?

  - by Sebastian

  I'm building a new computer and plan on using a few spare USB sticks with readyboost to cache disk writes. I'll be running Windows 7 Enterprise SP1 x64 I have a single 2 TB disk, and plan to make a partition for windows (100 GB) and use the rest for data. I know Readyboost will work nicely for the C drive, but am unable to find any information on whether it will accelerate a second drive or partition. Just to clarify, I'm NOT trying to use the harddrive instead of the usb sticks. I'm trying to speed up the second partition using the USB sticks So, will readyboost work for a secondary partion or harddrive?

• Run init.d script in the context of the current user session.

  - by akellehe

  I'd like to run a script in init.d (on Fedora) in the context of the user session I'm logging in as. I have a script called keyboard_deadkeys I wrote to set some deadkeys on my keyboard. The script is very simple: #!/bin/bash /usr/bin/xmodmap /home/julie/keymappings I put it in the directory /etc/init.d so it will run at boot time. It is also in /etc/rc.d/init.d I changed the permissions to a+rwx for good measure. When I boot; the deadkeys aren't set in the user's session. When I then run the script manually; the keys are set. How can I rectify this?

• Replacing a non-failing drive in a RAID-0 array [migrated]

  - by TallFurryMan

  I have a Windows 7 machine booting on a RAID-0 pair of 500GB disks, controlled by an ICH9R. One of those is indicating an end-To-end SMART failure. I added a spare disk as a temporary workaround, before receiving another to replace the failing one (prices are awful these days). The RAID-0 rebuilt on the spare and dropped the failing one from the array, as expected. Now that I received the new drive, what are my options to reintegrate it in the array? My first thought was to simply clone the temporary disk to the new one while the array is offline, but shouldn't there be a way to force a second rebuild, just as if the temporary drive had a warning, and drop that temporary from the array?

• CentOS I/O blocking flushing dirtypages

  - by user3662224

  I have an Apache webserver on CentOS. It is not doing anything fantastic or complicated at all but it does at intervals experience a high load (120 for 4 CPUs) for some reason. During this time I see high waits and write durations. I have narrowed this down to flushing of dirtypages to disk to make room for new data. I have tried many things and talked to the developers who are also puzzled by this. I am stumped. Details: vmware virtual guest server 4 cpus 12G RAM Apache PHP I have 40 servers in this cluster that share the same disk structure. Only the webservers are experiencing this issue. Any ideas?

• Why doesn't the Ubuntu Installer see all of my hard drives

  - by atodd

  I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed. I've tried everything I know. I'm not sure if its a BIOS setting or something else I've missed.

• Vostro 1520 crash during bios update

  - by Deadmilkman

  My Vostro 1520 (P8700 C2D) originally came with BIOS A02. This bios version have known problems with VT, so I had to upgrade to A05. During the upgrade, the notebook crashed. Needless to say, it won't boot anymore. The simple question is: is there a way to access the bios boot block to recover the bad flash with a crisis disk? I know that the MINI and the ALIENWARE models have this feature, but I can't seem to find anything about it in the Vostro machines. Any help will be much appreciated. PS: Dell's solution is to change the motherboard, but it will take several days, as the board isn't available in my country :( Regards, Deadmilkman

• Move 2TB Win7x64 to 640GB HDD

  - by reedacus25

  Basically I just got a new (refurbished) HP H8-1260t to use for Windows Media Center. The shipping drive is a 2TB Hitachi drive, but I have an older and barely used 640GB WD Caviar Blue 7200RPM drive I would like to move my Windows install to. I have about 750GB of data with over 1TB free left on the drive. Having googled my heart and fingers out, I would think that I can shrink my partition down to the size it is full at now with over 1TB free for a second partition where I can move my media files to further shrink my boot partition so that I can fit a system image smaller than 640GB on that WD drive. I want to have a separate drive for Media and TV Recordings from my boot disk. Does this sound like the easiest method for me? Or am I doing this all wrong. Help appreciated.

• Few questions about backing up the OS

  - by user23950

  I'm running windows 7 with 2gb memory and 2.50 Ghz dual core cpu. here are my question regarding backing up an entire drive. I plan to use Macrium Reflect because its free. And I can't afford to buy one. If I backup a hard drive would I only be able to backup the partition where the operating system is? If I have installed applications which requires activation keys, and I have already installed an activation key. Does backing the hard drive also backup those application, so that I won't have to re-apply the keys later? If I have a multi-boot system, would the backup also include those other OS that are installed in my hard drive? Can I still boot into them after restoring the image? Do you have any links there that could enlighten me on what drive backup really is. Thanks!

• Too Much Swapping, even though RAM is 2/3 Empty

  - by indyaah

  I have a VPS with 9GB RAM, 300GB HDD, 3 GB Swap, 7 Cores. The OS is CentOS 5.7 Final. I have postgres9.0 running on my machine, with proper tuning done (at least by book/wiki of PostgreSQL). What happens is most of the times when some complex query run (by complex I mean select with maximum 3 Joins), eventhough 66% of my RAM is unused there is ~99% swapping is happening. Plus it screws up my disk IO which is most of the time reaching ~100% and slows down everything else. (I tend to believe something's wrong with my disk.) I dont understand the reason of this much of swapping happening. Is it because of context switching?? Most of the time my processors are idle, while the IO wait goes upto 30% during pick times. Would appreciate if some can shed some light on it. Thanks.

• Why won't Windows XP 64 install on my machine?

  - by user272671

  I have a hp xw8200 workstation and would like to install Windowx XP 64 bit on it. Problem I seem to be having is when I reboot the machine and try to boot from the CD, nothing happens. Seems that the CD Drive is not being located or does not execute my cd to start the install. I already checked to verify that I can install Windows XP 64bit on my machine and also ensured I have the right bios and drivers for the install, only that the boot just does not take place. Anyone have any idea how I can solve this problem ? http://www.hp.com/workstations/pws/xw8200/xw8200.pdf http://h20331.www2.hp.com/Hpsub/cache/286710-0-0-225-121.html http://h20331.www2.hp.com/Hpsub/cache/286707-0-0-225-121.html thanks in advance
