• XFS and loss of data when power goes down

  - by culebrón

  Each time electricity goes down, my desktop (without UPS) loses some temporary information. Opera can lose settings, history, cache, or mail accounts (Thanks heavens I was wise to use IMAP). Partially or all together. a whole file (complete and save) in Geany appeared empty (and I didn't commit it to Git) rhythmbox lost all podcasts subscription data I'm afraid there are other losses I just didn't see. What's the reason? A memory files cache, a mem-disk? Or non-atomic file writes in xfs? I have Ubuntu 9.10 and XFS on both / and /home partitions. Is ext4 safer in such circumstances? I've seen ext3 is faster. Is it as safe as *4? Given that the apartment I rent is connected to a common bus and 1 safety switch for several apartments, and the neighbors - alone or together - overload it at least once every week, the lights go down often enough for this to be an issue.

• Hiding a file or data from being accessed unless on scheduled days [closed]

  - by gkt.pro

  Possible Duplicate: restricting access to volumes disk even for admin account windows How to restrict use of a computer? I want to limit my access to some data and what I want is that I should be able to access the data only on certain days of the month (e.g., every 3rd day). Is there any way like encryption or some utility to allow me to only access data on specific days? One idea that I was thinking of was to encrypt the data and store the password (will be complex and long so that I couldn't remember it right away) on some website which would then email me back the password in future on those specific days.

• What is the best way to clone Win7 machines?

  - by John Hoge

  I'm looking to buy 5 new Win7 boxes and would like to ease deployment by cloning the OS. What I would like to do is install a fresh OS (Dell doesn't seem to sell machines without preinstalled crapware anymore) and then install a few apps on the first one. Once it is just right, I want to clone the OS and install the image on the other four machines and just change the machine name. Is this possible to do without any extra third party software? What I am thinking of doing is backing up the disk image of the first machine to a network share, and then booting the others to the windows install DVD and restoring the same image on each machine. Has anyone had any luck with this technique?

• What is the best software to capture full-screen 3h programming session in Windows?

  - by Hugo S Ferreira

  Hi, I'm planning a laboratorial experiment to assess behavior of groups when programming using some tools under study. For that, I'll need to capture their entire screen to disk. Mostly, what will be displayed is code, so I'm not to worried with image quality. However, it's paramount that the team is not able to stop the recording by accident, and the tool should be rebust enough to hold at least 3h of video. If possible, it would be nice for researchers in other rooms to "watch" the video as it is recording. Actually, this last requirement reminded me that I could use a VNC recording software, and install a VNC client in each laboratory computer. Anyway, what is your experience with this? Which software do you recommend? Thanks.

• Mac OSX: Adobe Flash player 10.1.85.3 text issue

  - by sparkey

  Running Flash Player 10.1.85.3. on OS-X 10.6.4 I've run into a very strange issue with Adobe/Macromedia Flash. Text in dialogs sometimes is not displayed, and the containing boxes are distorted. It occurs in all browsers. This is best demonstrated on YouTube in some of their ads, as well as in Google Analytics overlays on graphs. You can see the issue here: As you can see, where I have moused over the high point, there should be a dialog with some text, but instead it is quite broken. I've tried uninstalling and reinstalling the Flash plugin several times, reinstalling Google Chrome, validating my fonts with FontBook (removed all dupes/ fonts with warnings). Also as a last resort I checked/ repaired perms on my disk. What should I do?

• Connection to SQL Server 2008 R2 Database Server is SLOW

  - by AbeP

  The database server is a VM running SQL Server 2008 R2 on top of Windows Server 2012, 24GB RAM allocated and 2TB of disk space. Overall, the database connections are very slow and one thing that stands out is that the connection to the database server via SSMS takes 5-10 seconds. On other much less powerful servers, it takes 1-2 seconds. The VM is technically way more powerful than other machines, but the connection to the server is too slow. So, my guess is the issue is network related, but any clues on where I should be looking? Thanks!

• Plugging GlusterFS and Openfiler together

  - by lpfavreau

  Has anyone had experience plugging GlusterFS and Openfiler together or something similar? Here is the motivation: Disk space on multiple server regrouped using GlusterFS Centralized access using LDAP/AD and quota management using Openfiler as the GlusterFS client SMB/CIFS server for easy sharing to multiple users on Mac and Windows I know I can have Gluster installed on Openfiler (rPath Linux) successfully but Openfiler seems to be very picky on what it can use as a shared drive. Mounting the Gluster volume inside an existing share does not seem to allow quotas with the mounted folder free space. If this is not possible, is there any alternative to give the same capabilities?

• Windows 7 CRC Error When Installing Fallout 3 [closed]

  - by c00lryguy

  Earlier today, I installed Fallout 3 on Windows XP perfectly fine. Then about 2 hours ago I installed Windows 7 and I would like to install Fallout 3. But, when I try to install Fallout 3 on Win 7, I get an error while in the middle of the install: CRC Error: The File C:\Program Files\Bethesda Softworks\Fallout 3\Data\Video\B03.bik doesn't match the file in the setup's.cab file I forget the filename but it is the same each time I install. The disk literally went from the DVD-Rom to the case after the first install and straight from the case to the DVD-Rom. It's in perfect condition. My DVD-Rom is only about 2 months old and I've never had any problems with it. I don't understand what's going on. My user that I'm installing the game with is set as Administrator, as well.

• Is it possible to fake a Windows install for grub to add to boot menu?

  - by Mussnoon

  When doing a fresh install of a Linux distro (Ubuntu, for instance) on a fresh hard drive, if I want to install Linux first, and Windows later, is it possible to make grub think there's a Windows install on the first partition so that it'll be added to the boot menu after the installation is complete? To illustrate, I have a new hard drive and have created two primary partitions (both still raw) and two logical (Ext4 and Swap). I want to install Ubuntu on the Ext4 partition first, and some version of Windows on the first primary partition only after that (because I currently don't have a Windows install disk, but do have one for Ubuntu). Is it possible to make Ubuntu add an entry for Windows right now and avoid having to repair grub after I've installed Windows?

• Win 7 accessing large files uses 100% RAM

  - by user181276

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

• few questions on making a flash drive to a hard drive

  - by user23950

  I've found a tutorial here on how to trick the operating system to see a flash drive as a hard drive. http://www.getusb.info/usb-hack-turn-a-usb-stick-into-a-hard-drive-or-local-disk/ But I have a few questions: This trick will only work on the os wherein you updated the flash drive driver. Is there a trick that will work like this one, but if you plug in the flash drive to another computer it will still be treated as hard drive? How do I convert it back to a flash drive?

• White Screen of Death

  - by cust0s

  The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death. I use an early 2008 iMac 24". I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc. Still no luck and no change what-so-ever. All I've been able to ascertain that my keyboard still works (by ejecting). I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen.

• How to backup blog running on posterous.com

  - by Martin Vobr

  I'd like to backup content of my blog which is powered by posterous.com. I'd like to save all texts and images to the local disk. Ability to browse it offline is a plus. What I've already tried: wget wget -mk http://myblogurl It downloads the first page with list of posts, then stops with "20 redirections exceeded" message. WinHttpTrack It downloads the first page with redirection to the www.posterous.com home page instead of real page content. Edit: The url of the site I'm trying to backup is blog.safabyte.net

• Why won't the floppy mount?

  - by dboarman-FissureStudios

  The 1.44Meg floppy won't mount in my Nautilus file browser. When I try to mount it, it says there is no media in the drive. Yet, I can write to the floppy through the terminal using the 'cp' command. I can enter the command: mount -t ext2 /floppy and it mounts. I have also run a check and the disk itself is 100% clean. So, why can't I get the nautilus browser to open up the floppy? Is there a way to see the actual floppy from the terminal?

• Good Linux Distro for Disconnected Netbook

  - by MrWizard54

  I'm deployed to Afghanistan with the Army and I have a friend who's netbook had his hard drive take a dump on him. He ordered a new hard drive and I was able to download and burn a copy of Ubuntu to disk from work. However the default install doesn't support most of the media that he wants to watch (AVI files, probably some DIVX video) without installing extra packages. We don't have internet in the tent and really don't have a vaiable option for downloading additional packages through the package manager anywhere here. The computer is a small HP netbook. All my friend wants is to watch ripped movies. Does anyone know of a good way to do either of the following: Download packages seperately and install them via CD A distro that is going to come preloaded with all of the packages and needed to watch just about any type of video file you can think of? Thanks in advance, Andy

• How tot track which program causes my harddrive to spin up

  - by Andreas

  I have a strange problem: Every half hour one of my hard disks gets powered on again. I recognize this by the sound of a hard disk spinning up. So far I was not able to track which program could cause this. I ran Process Monitor to see whether there is an I/O peak coinciding with the spin-up. I checked Windows event viewer if there is an appropriate event at the same time Any ideas other than the usual disabling-services/programs etc. (which would be my next investigation step)? Also, it would be helpful to have a program that shows the current power status of all my drives, if there is one. Harddisk Sentinel unfortunately cannot do the job because it powers on all drives upon start and prevents their going into sleep mode. Thanks in advance. :)

• Can I trust that ZFS is consistent between Linux and FreeBSD?

  - by iconoclast

  I'm planning to build a FreeNAS box sometime soon, but if ZFS on Linux eventually proves to be reliable, I might want to switch, just to have a more familiar OS. So I'm wondering if I can trust that the different implementations of ZFS are compatible. In other words, if I just swap out the boot disk from FreeNAS to Linux or OpenIndiana, can I trust that nothing bad will happen to my data? This may seem like a stupid question--obviously it ought to be compatible--but I'm guessing that ZFS isn't commonly used in cases where drives are moved between computers, so I'm hoping someone can provide a better answer than just "it ought to be".

• How does NTFS compression affect performance?

  - by DragonLord

  I've heard that NTFS compression can reduce performance due to extra CPU usage, but I've read reports that it may actually increase performance because of reduced disk reads. How exactly does NTFS compression affect system performance? Notes: I'm running a laptop with a 5400 RPM hard drive, and many of the things I do on it are I/O bound. The processor is a AMD Phenom II with four cores running at 2.0 GHz. The system is defragmented regularly using UltraDefrag. The workload is mixed read-write, with reads occurring somewhat more often than writes. The files to be compressed include personal documents and selected programs, including several (less demanding) games and Visual Studio (which tends to be I/O bound more often than not).

• Not able to access a folder in Windows 7 and not able to see in Ubuntu.

  - by Rohit

  I have four partitions on my hard disk. Partition C has Windows XP installed and Partition G has Windows 7 installed. Ubuntu 10.10 is also installed, probably in F. Partitions C and G are NTFS. When I boot into C, XP is loading but when I click on the C Drive in MyComputer, it displays: "Access is denied". Windows 7 displays the folder tree of C, but when I try to open a folder, I am not able to view the contents. The same error: of Access Denied. When I try to view the C Partition using Ubuntu, the entire C partition is not visible. I tried following commands to take ownership of the C drive: takeown /f C: cacls C: /G Rohit:F but still I am not able to get rid of "Access Denied". I again tried the above commands from the Windows 7 safe mode, but still the problem persists. The two commands return "Successful", but nothing is happening.

• 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.

• IIS Logs not getting created

  - by Chris

  Hi I have a site running on IIS 6. I have turned on logging on the website tab of IIS and specified a directory for it to write to. Set it to an hourly schedule. However no logs are ever created. Have reset iis. checked disk space and permissions on the directory it is writing to but no logs are ever created. I can see this did work once, as there are logs created in the system32/logfiles directory from about a year ago. Even if I specify that directory nothing new gets created This is on a hosted service What else can I check? Is there any place that errors would be written to that might give me a clue as to what is going on? Have tried event viewer but nothing untoward in there Would appreciate any pointers on this

• Plesk file permissions - Apache/PHP conflicting with user accounts.

  - by hfidgen

  Hiya, I'm building a Drupal site which performs various automatic disk operations using the apache user (id=40). The problem is that the site was set up on a subdomain belonging to user ID 10001 (ie my main FTP account) so the filesystem belongs to that user ID. So I keep getting errors like this: warning: move_uploaded_file() [function.move-uploaded-file]: SAFE MODE Restriction in effect. The script whose uid is 10001 is not allowed to access /var/www/vhosts/domain.com/httpdocs/sites/default/files/images/user owned by uid 48 in /var/www/vhosts/domain.com/httpdocs/includes/file.inc on line 579. I've tried changing the apache group in httpd.conf to apache:psacln, psacln being the default group for all web users but that's not helped. The situation now is: ..../files/images/ = 777 and chown = ftplogin:psacln ..../files/images/user = 775 and chown = apache:psacln ..../files/tmp = 777 and chown = ftplogin:psacln So apparently uid 40 and 10001 both have permissions to write to any of the 3 directories involved, but still can't. Am i missing something here? Can anyone help? Thanks!

• iPhone: "there was a problem downloading this podcast"

  - by brianegge

  I have several podcasts which work perfectly fine in iTunes, but when I attempt to download additional episodes on the iPhone I get the message "there was a problem downloading this podcast" once the download completes. All I can find points to my iPhone not having enough disk space. The settings tells me I have 1GB available. I've also tried deleting some content and receive the same message. Originally, I thought this might be due to the RSS feed indicating a different file size than the media file, but I manually verified its correct. A podcast which I can always reproduce this problem has the following feed: http://www.podquiz.com/rss.php I can reproduce the problem on both WiFi and 3G.

• Mac Book Refuses to Boot

  - by pas09

  I have a Macbook that has unfortunately died on me. I randomly got a pop up message that said I needed to restart my computer, and once I did, I was greeted with the blinking folder question mark start up screen. I've tried everything, including running Disk Utility repair and reformatting the hard drive and reinstalling OS X. All of my data is backed up and safe, I just need my computer to start again. Before I go off and buy a new hard drive, I wanted to see if there is anything I might have forgotten.
