Advice on cloning disk

- by hks

I'm going to buy a second disk for backup, the same size as my laptops. I want to mount it in a casing via usb and backup an entire hdd every soemtime. That's because I want the posibility to just switch drives in case of something goes wrong. I'm using Linux and obviously the right tool seems to be dd. The thing is that my laptop drive has a speed of around 50-70 MB/s and usb 2.0 is 57 MB/s. So to copy my 250GB disk should take me more than 1 hour if I'm lucky. I can't wait this much. I want some differential backup. I read one of JWZ articles. In it he gives more details for using rsync on Mac. He writes that there is possibility of making rsync'ed disk bootable. So my question is: how to make rsync'ed hdd bootable under Linux or are there other 'quick backup' tools for Linux that would allow me to just swap drives? Or should I just stick to dd :( ?

Windows Broken after Deletion of HP_TOOLS partition

- by beanland

When I decided to install Ubuntu on my laptop as a dual-boot, I recognized that Windows 7 was using four separate partitions. I (yes, this was stupid) thought the HP_TOOLS partition was probably one I could get rid of, so I deleted it and installed Ubuntu side-by-side Windows using the installation wizard, but now Windows won't progress past the loading screen without the computer automatically restarting. I've had to use Ubuntu exclusively since then. I'm not sure how I can recover it. All of my files seem to still be there--I can mount the other partition and see them, use them, etc--but Windows 7 won't boot. I really have no idea what to do or what to try, or even if I'm at a salvageable point. here's a screenshot of GParted: This makes me suspicious that it wasn't necessarily the removal of my HP_TOOLS partition but the "unknown" status of that 992.50 KiB partition there, sda1. I'm assuming that's the recovery one? How can I get Windows bootable again? I'm sorry, but I'm so unfamiliar with this sort of thing I'm not quite sure where to start.

Network external hard drive reports not enough free space

- by mzhang

I'm running an Ubuntu (10.04) Samba server on a local network. The server has a 50GB internal drive with only 24MB free. I've shared a folder /samba from that drive. I also have a 1TB NTFS external hard drive mounted to the system. There is a symbiotic link from the Samba shared folder on the nearly-full internal drive to the plenty-of-free-space external drive (i.e. /samba/external_hd). I wish to copy a 3.25GB folder into the (remote) external hard drive, via a Mac (10.6.8). The Mac reports (correctly) that there's 24MB free on the server, and so will not let me copy the folder on the Mac over to the external drive (dragging the folder into /samba/external_hd), failing with a "server does not have enough free space" error. However, it seems that I can still scp the folder into the external drive, via the symbolic link. Is there a reason as to why this is happening (and are there any ways to prevent it)? Is this even good practice (to mount a drive and link into the directory)?

Inexpensive (used) hardware for Xen virtualization test?

- by Jason Antman

Virtualization is one of the areas where I could really use some experience. I also run quite a few services (web, mail, dns, etc.) out of my home. Since most of my hardware is getting a bit old (I'm running on stuff that was surplused years ago...) I decided that it's about time I start renewing some things, and also play around with virtualization a bit more. My plan is to setup a SAN box (simple iSCSI target, relatively inexpensive gigE switch), get a pair (for starters) of new servers, and start building some new stuff with Xen, specifically planning on playing with live migration and full virtualization. Does anyone have recommendations for used, older "servers" (really anything in a rack-mount form factor, I'm not too worried about things like iLO/iLOM for the test nodes) that support VT-x/AMD-V? I'm biased to HP, but it looks like they didn't make Proliants with VT-x/Vanderpool processors until G6 (for the DL360) or so, which is way out of my price range. I'm looking in the sub-$300 range (or less, if possible), used, probably Ebay. Any recommendations are greatly appreciated. Edit:And, to catch this before the comments start coming - these are personal systems. I have first-generation Proliants still in use (I got them as corporate surplus in 05, they've been running since then, and probably were running since 01 or 02 prior to being sold). I don't need anything shiny and new - I've got a bunch of old boxes, at least one complete replacement for every model in use, and that's fine for me (and easy on the wallet).

Question marks showing in ls of directory. IO errors too.

- by jaymoo

Has anyone seen this before? I've got a raid 5 mounted on my server and for whatever reason it started showing this: jason@box2:/mnt/raid1/cra$ ls -alh ls: cannot access e6eacc985fea729b2d5bc74078632738: Input/output error ls: cannot access 257ad35ee0b12a714530c30dccf9210f: Input/output error total 0 drwxr-xr-x 5 root root 123 2009-08-19 16:33 . drwxr-xr-x 3 root root 16 2009-08-14 17:15 .. ?????????? ? ? ? ? ? 257ad35ee0b12a714530c30dccf9210f drwxr-xr-x 3 root root 57 2009-08-19 16:58 9c89a78e93ae6738e01136db9153361b ?????????? ? ? ? ? ? e6eacc985fea729b2d5bc74078632738 The md5 strings are actual directory names and not part of the error. The question marks are odd, and any directory with a question mark throws an io error when you attempt to use/delete/etc it. I was unable to umount the drive due to "busy". Rebooting the server "fixed" it but it was throwing some raid errors on shutdown. I have configured two raid 5 arrays and both started doing this on random files. Both are using the following config: mkfs.xfs -l size=128m -d agcount=32 mount -t xfs -o noatime,logbufs=8 Nothing too fancy, but part of an optimized config for this box. We're not partitioning the drives and that was suggested as a possible issue. Could this be the culprit?

Output current with Teensy++ 2.0 (arduino-based hardware)

- by omtinez

I am working on a project with a Teensy++ 2.0 for testing, eventually the goal is to use a Teensy 2.0 (info on both available here) and mount it onto a robot R/C car along with a Raspberry Pi. I have been able to use and test one of the very cheap distance sensors that use ultrasound, which requires very little current. I was trying to power a motor, I don't know exactly what kind of motor but I assume a very low-power one which is what comes with the R/C car cheapo, but nothing is happening. When I plug the motor to GROUND and +5V it runs fine, but when I use GROUND and one of the GPIO pins then nothing happens with the motor. The same GPIO pins were tested to successfully power and run the ultrasound sensor, so the board is fine. My suspicion is that the GPIO pins don't output enough current to power the motor, but my knowledge of electronics is rather scarce (I am a computer scientist, not an electrical engineer). So please forgive me if I am asking something obvious or plain stupid, but does the board not have enough power to power the motor? If so, I could try to use a second power supply that would go straight into the motor and use the GPIO as a gate to turn that power on and off; would such thing work? Is there a better design that could be used?

Running Windows 7 physical disk virtualized under Linux

- by CajunLuke

I have an existing Windows 7 installation that I'd like to virtualize under Linux. Windows boots fine on Disk A, Linux boots fine on Disk B. (Both disks are SATA.) I can mount the Windows disk when in Linux. I've tried VirtualBox and VMWare Player and neither will allow me to boot from the other disk. VirtualBox doesn't seem to have the option to do so. VMWare Player has the option to have an IDE drive exposed to the virtual environment as a SCSI disk. I've tried that, but it throws the error "Cannot connect virtual device ide1:0 because no corresponding device is available on the host." I've verified that it's pointing to the correct hard drive. I'm willing to try other virtualization products, and I'm not averse to spending a little money to get this to work. I've seen this other question, and it's not a duplicate, as I haven't gotten that far yet. I'm also interested in solutions going the other way (Linux on Windows), but that'd be lagniappe. Gory Hardware Details: Lenovo T410, 2.4 GHz Core i5 (has virtualization extensions), 4GiB RAM, 2x 320 GiB SATA HDD, one in optical bay. Fedora 14 2.6.35.10-74.fc14.x86_64, Windows 7 32-bit.

Disk (EXT4) suddenly empty without any sign of why

- by Ohnomydisk

I have a Ubuntu 10.04 server with several disks in it. The disks are setup with a union filesystem, which presents them all as one logical /home. A few days ago, one of the disks appears to have suddenly 'become empty', for lack of better explanation. The amount of data on the /home mount almost halved within minutes - the disk appears to have had just over 400 GB of data prior to 'becoming empty'. I have absolutely no idea what happened. I was not using the server at the other time, but there are half a dozen other users who may have been (without root access and without the ability to hose a whole disk). I've ran SMART tests on the disk and it comes back clean. The filesystem checks fine (it has 12 GB used now, as some user software continued downloading after the incident). All I know is that around around midnight on October 19, the disk usage changed dramatically: The data points are every 15 minutes, and the full loss occured between captures: 2012-10-18 23:58:03.399647 - has 953.97/2059.07 GB [46.33 percent] 2012-10-19 00:13:15.909010 - has 515.18/2059.07 GB [25.02 percent] Other than that, I have not much to go off :-( I know that: There's nothing interesting in log files at that time Nobody appeared to be logged in via SSH at the time it occured (most users do not even use SSH) The server was online through whatever occured (3 months uptime) None of the other disks were affected and everything else on the server looks completely normal I have tried using "extundelete" on the disk and it didn't really find anything (some temporary files, but they looked new anyway) I am completely at a loss to what could have caused this. I was initially thinking maybe root escalation exploit, but even if someone did maliciously "rm" the disk contents, it would take more than 15 minutes for 400 GB?

How can I undo what I did when I accidentally booted linux host inside itself with VMware?

- by ThomasGHenry

Hello, I'm dual booting XP and Kubuntu. I wanted to boot to my existing raw scsi XP partition inside Kubuntu, not a virtual XP instance. I accidentally booted Kubuntu inside itself. I know this is a big mistake, so I interrupted the VM, which saved the state and closed. I rebooted the host and now I can't load the Kubuntu partition at boot time. I get a maintenance shell and the Kubuntu partition is read-only. I am able to boot XP as usual. I removed the HDD and tried to mount it on another computer as an external drive and neither partition (XP or Kubuntu) will be recognized, it just appears to be one device that still mounts and appears empty. From the maintenance shell I can see all the files are still on the Kubuntu partition. How can I undo what I did when I accidentally booted Kubuntu inside itself? Is it a matter of unlocking some files somewhere? how can I do that on a RO filesystem? Thanks!

Is it possible (and how if it is) dump two concatenaded disks in a new disk using DD?

- by pedromarce

Hi, I have a Lacie enclosure that has a setup with 2 500gb disks configured as 1 drive of 1TB, the only partition created for the whole drive is HFS+ journaled, but the controller in the enclosure is gone and so the drive refuses to mount anymore. I have been able to remove those two disks from the enclosure and connect them using USB ports and a program called R-studio (Raid recovery program) check that the setup the controller in the enclosure was using was both disks concatenated (Not Striped). And so configuring that option in R-studio I could be able to get back all the information. But before I got a license for r-studio for just one use, I would rather buying a new 1TB disk and try to write all the information of those two disks in this new one. I can use Mac or linux machines to do it, and I think it should be ok use DD command in linux to concatenate those two drives into the new one in the right order to get it working again in the new disk and I will reformat the old ones, but I am not sure. So, is it possible in this scenario to write both disks into a new one using DD? Any hints how the command would look? Thanks,

Raspberry Pi how to format HDD

- by Speed

Hi I am very new to Raspberry Pi environment, so looking for a bit of help to format a usb hard disk drive. I ran lsblk and got sda 8:0 0 37.3G 0 disk sda1 8:1 0 37.3G 0 part looking on web, if tried the following "sudo mkfs.ext4 /dev/sda1 -L USB40gb" it did something but when I tried to mount the drive again, it still showed the files that were there before and I can not create new file/folder "Error creating directory: Permission denied" I am writing this from my windows 8.1 pc so can not cut and paste from the pi. trying to format its output is a bit hard. Oh, there is Nothing written after the word "part" above. There use to be /media/USB40gb so I have done something because this has disappeared. I am using PCManFM 0.9.10 It does not have a format option, which would make life a lot easier, but then its not windows. I think I am running the basic linux os for the pi. It boots to a graphic environment, but I do not know how to advise what it is. I think its OpenBox 2.0.4 Thanks in advance Speed PS: I reran the format string above but this time I changed the label to read USB37gb. I did this to confirm that I was in fact formatting the right drive. Low and behold, it actually formatted the drive, wiping everything from it. Great ... testing it by creating a new folder on the drive and get error msg Permission Denied! So I have fixed the formatting issue by trial and error but still can't use the drive... Suggestions anyone?

PowerShell Control over Nikon D3000 Camera

My wife got me a Nikon D3000 camera for Christmas last year, and Im loving it but still trying to wrap my head around some of its features. For instance, when you plug it into a computer via USB, it doesnt show up as a drive like most cameras Ive used to, but rather it shows up as Computer\D3000. After a bit of research, Ive learned that this is because it implements the MTP/PTP protocol, and thus doesnt actually let Windows mount the cameras storage as a drive letter. Nikon describes the use of the MTP and PTP protocols in their cameras here. What Im really trying to do is gain access to the cameras file system via PowerShell. Ive been using a very handy PowerShell script to pull pictures off of my cameras and organize them into folders by date. Id love to be able to do the same thing with my Nikon D3000, but so far I havent been able to figure out how to get access to the files in PowerShell. If you know, Id appreciate any links/tips you can provide. All I could find is a shareware product called PTPdrive, which Im not prepared to shell out money for (yet). (and yes you can do much the same thing with Windows 7s Import Pictures and Videos wizard, which is pretty good too) However, in my searching, I did find some really cool stuff you can do with PowerShell and one of these cameras, like actually taking pictures via PowerShell commands. Credit for this goes to James ONeill and Mark Wilson. Heres what I was able to do: Taking Pictures via PowerShell with D3000 First, connect your camera, turn it on, and launch PowerShell. Execute the following commands to see what commands your device supports. $dialog = New-Object -ComObject "WIA.CommonDialog" $device = $dialog.ShowSelectDevice() $device.Commands You should see something like this: Now, to take a picture, simply point your camera at something and then execute this command: $device.ExecuteCommand("{AF933CAC-ACAD-11D2-A093-00C04F72DC3C}") .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Imagine my surprise when this actually took a picture (with auto-focus): Imagine what you could do with a camera completely under the control of your computer Time-lapse photography would be pretty simple, for instance, with a very simple loop that takes a picture and then sleeps for a minute (or whatever time period). Hooked up to a laptop for portability (and an A/C power supply), this would be pretty trivial to implement. I may have to give it a shot and report back.

Enable Full Screen Mode in Media Center Without Trapping the Mouse

- by DigitalGeekery

If you have a dual monitor setup and use Windows Media Center, you’re probably aware that when WMC is in full screen mode, it traps the mouse so you can’t work on a second monitor. Here we look at how to solve the annoyance. The Maxifier is an application that allows you to open Media Center in full screen mode without restricting the mouse. It relieves the annoyance of WMC capturing your mouse on a dual monitor setup. Note: If you don’t have two monitors attached, most of The Maxifier’s functions won’t work. Installation and Use Download, extract, and install The Maxifier. (See the download link below) The Maxifier runs minimized in the system tray and you access the options by right-clicking on the icon. If Media Center is not already open, you can choose Start Media Center to start WMC on the main start screen. Or, choose one of the other selections to open another area of Media Center. By default, Maxifier opens Media Center in full screen mode on the secondary monitor. When Media Center is open in full screen mode, you’ll notice you can now freely move your mouse around your multi-monitor setup. When Media Center is open, you’ll see five additional options. The Fit Screen options simply fits Media Center to the full screen, but still show the Windows borders. Full screen options put WMC in full screen mode. The Maxifier Options allow you to choose from the various start up options. Selecting Watch for Media Center starting will prompt Maxifier to open WMC to the main start page in full screen mode on the secondary monitor automatically, even if you open Media Center without using The Maxifier. (You may need to restart for this to take effect) If you have more than 2 monitors, you can define on which monitor to open Media Center, and which monitor you consider to be the main screen. You can also define a number of Hotkeys in The Maxifier settings. First, select the Enable Hotkeys checkbox. To create a Hotkey, click in the text field and then press the keys to use as the Hotkey. To remove a Hotkey, click in the field and press the Delete key. Conclusion The Maxifier is a simple program that enables Media Center users to take full advantage of a multi-monitor workspace. It works with both Vista and Windows 7. Version 1.4 is a stable application for Vista, and Version 1.5b is a beta application for Windows 7. Looking for more Media Center tips and tweaks?

12.04 installation started to black screen during boot today

- by Cedric

NOTE: Most of this question is now irrelevant. UPDATE 3 summarizes the problem as it stands. I've been running 12.04 on my Lenovo laptop for one month now (updated from 11.04), and I have not had any significant problem until today. This morning, when I boot, I pass the Grub screen, then I get to the purple loading screen with dots as usual, then for some reason I got to the terminal login, with no GUI. startx gives me a black screen. Ctrl+F7-F8 didn't help either. It's similar to: After the update today no graphical interface anymore - 12.04 I followed the instructions at the end, to flush the ATI drivers (which I had installed), and fall back to the community drivers. That made me lose the login! Now I just get a black screen after the Ubuntu loading screen. I can still access the console through recovery, and I've gotten into VESA mode once or twice (not reproducible, for some reason). I've tried various permutations of xorg.conf, without success. Xorg -configure fails for now, though I might be able to get it to work. apt-get update/upgrade doesn't improve anything either. However, both Windows and the 12.04 Live CD still work beautifully, and I know that all my data is still there. Is there any way that I could somehow take the configuration from the Live CD and roll with it? I know that I could reinstall, but that sucks, frankly, especially given that there's no straight-forward way of keeping the home (which, incidentally, is unaccessible from the Live CD) Thank you. Update: it seems that the fglrx drivers are still active, even after I've --purged them. From Xorg.0.log: [ 18.235] (WW) fglrx(0): *********************************************************** [ 18.235] (WW) fglrx(0): * DRI initialization failed * [ 18.235] (WW) fglrx(0): * kernel module (fglrx.ko) may be missing or incompatible * [ 18.235] (WW) fglrx(0): * 2D and 3D acceleration disabled * [ 18.235] (WW) fglrx(0): *********************************************************** [ 18.235] Fatal server error: [ 18.235] AddScreen/ScreenInit failed for driver 0 There's also a mention of the "fbdev" module. What is it? PARTIALLY SOLVED: I've undone the damage from the fglrx purge. I'm still mystified as to why uninstalling the packages didn't kill fglrx entirely, but I've now recovered the prompt. The solution to the DRI initialization error was to add radeon.modeset=0 to the GRUB boot options. So I'm back to being dropped to a prompt without any GUI. startx gives me a bunch of messages, though no obvious errors. I have little reason to suspect the video drivers, as they worked fine before today. There is no apparent error message in any of the log files. UPDATE: When I startx, I get an error, Plymounth command failed mountall: Disconnected from Plymouth This is all over the Internet, but I have not found anything that works for me yet. UPDATE 3: If I press ESC during boot, the splash screen (Plymouth!) disappears, and I no longer have any error from Plymouth. The last error message is: Stopping mount filesystems on boot I can then Ctrl+Alt+F1 to get the TTY1, but startx still does not work. Sadly, the Internet knows nothing about this error message, and neither do I. Help!

How do I fix a corrupted harddrive after failed upgrade?

- by Nil

The problem originated when I was trying to fix this problem. Things went horribly, horribly wrong and I ended up with a new problem altogether. The last thing I did was run sudo apt-get install and that caused my system to freeze. I restarted my computer and it would not boot from the harddrive. I ran a copy of Ubuntu 12.10 from a flashdrive that I had and ran gparted to see if my partitions were all there. It returned this message: Invalid partition table on /dev/sda -- wrong signature 5208. The drive appeared as a 2TiB unallocated drive with an error. The drive had 4 partitions before (plus random unallocated space). There was a fat32 partition, an ext4 partition which contained ubuntu 13.04/13.10 (I don't even know which one at this point), an extended partition which contained a swap partition for my ubuntu partition (I was meaning to move that ubuntu partition into the extended partition, never got around to it), and another partition (I don't remember how I formatted it). I should also mention this is a 1TB harddrive. So in short, I have a corrupted partition table on my primary harddrive from which I boot from, how can I fix this?

Get to Know a Candidate (9 of 25): Gary Johnson–Libertarian Party

- by Brian Lanham

DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Johnson served as the 29th Governor of New Mexico from 1995 to 2003, as a member of the Republican Party, and is known for his low-tax libertarian views and his strong emphasis on personal health and fitness. While a student at the University of New Mexico in 1974, Johnson sustained himself financially by working as a door-to-door handyman. In 1976 he founded Big J Enterprises, which grew from this one-person venture to become one of New Mexico's largest construction companies. He entered politics for the first time by running for Governor of New Mexico in 1994 on a fiscally conservative, low-tax, anti-crime platform. Johnson won the Republican Party of New Mexico's gubernatorial nomination, and defeated incumbent Democratic governor Bruce King by 50% to 40%. He cut the 10% annual growth in the budget: in part, due to his use of the gubernatorial veto 200 times during his first six months in office, which gained him the nickname "Governor Veto". Johnson sought re-election in 1998, winning by 55% to 45%. In his second term, he concentrated on the issue of school voucher reforms, as well as campaigning for marijuana decriminalization and opposition to the War on Drugs. During his tenure as governor, Johnson adhered to a stringent anti-tax and anti-bureaucracy policy driven by a cost–benefit analysis rationale, setting state and national records for his use of veto powers: more than the other 49 contemporary governors put together. Term-limited, Johnson could not run for re-election at the end of his second term. As a fitness enthusiast, Johnson has taken part in several Ironman Triathlons, and he climbed Mount Everest in May 2003. After leaving office, Johnson founded the non-profit Our America Initiative in 2009, a political advocacy committee seeking to promote policies such as free enterprise, foreign non-interventionism, limited government and privatization. The Libertarian Party is the third largest political party in the United States. It is also identified by many as the fastest growing political party in the United States. The political platform of the Libertarian Party reflects the ideas of libertarianism, favoring minimally regulated markets, a less powerful state, strong civil liberties (including support for Same-sex marriage and other LGBT rights), cannabis legalization and regulation, separation of church and state, open immigration, non-interventionism and neutrality in diplomatic relations (i.e., avoiding foreign military or economic entanglements with other nations), freedom of trade and travel to all foreign countries, and a more responsive and direct democracy. Members of the Libertarian Party have also supported the repeal of NAFTA, CAFTA, and similar trade agreements, as well as the United States' exit from the United Nations, WTO, and NATO. Although there is not an officially labeled political position of the party, it is considered by many to be more right-wing than the Democratic Party but more left-wing than the Republican Party when comparing the parties' positions to each other, placing it at or above the center. In the 30 states where voters can register by party, there are over 282,000 voters registered as Libertarians. Hundreds of Libertarian candidates have been elected or appointed to public office, and thousands have run for office under the Libertarian banner. The Libertarian Party has many firsts in its credit, such as being the first party to get an electoral vote for a woman in a United States presidential election.

Nec USB 3.0 controller drops connection - Ubuntu 12.04.1

I have some serious problems with Technaxx pci-e 302p card. It has uPD720200a NEC chip with 4020 firmware. BIOS recognises it.

Converting a PV vm back into an HVM vm

- by wim.coekaerts

I have been doing some Oracle VM benchmark stuff in the last week or 2 in my off hours and yesterday I wanted to convert one of my VMs that was based on a paravirt kernel into a vm that just boots as a regular hardware virt VM with a standard x86-64 kernel. It took me a little while to figure out the fastest way so now that I have it pretty much down I wanted to share the steps. A PV kernel uses pygrub and a paravirt kernel image that lives on the vm image virtual disk. since this disk image does not have to be bootable it doesn't contain a boot sector and if you just restart the VM in hvm mode the virtual bios will just not do much as it can't start the boot process from disk The first thing I do is make a backup of my vm.cfg file :-) and then edit it as follows : the original file contains : bootloader = '/usr/bin/pygrub' I replace that with : acpi = 1 apic = 1 builder = 'hvm' device_model = '/usr/lib/xen/bin/qemu-dm' kernel = '/usr/lib/xen/boot/hvmloader' then changing the disk files. I change my xvd disks to hd disks and I copy over the iso image of my instal lDVD. In the case of my VM template it was based on OL5U4 So I downloaded Enterprise-R5-U4-Server-x86_64-dvd.iso and added it as a cd device. disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,xvda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,xvdb,w', ] to disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,hda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,hdb,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Enterprise-R5-U4-Server-x86_64-dvd.iso, hdc:cdrom,r', ] boot='d' for the network devices (vifs) I change : vif = ['bridge=xenbr2,type=netfront'] to vif = ['bridge=xenbr2,type=ioemu'] That should do it. Next, inside the VM, I copy over the regular kernel rpm that I want to end up running in hvm mode. In this example case it was : kernel-2.6.18-164.0.0.0.1.el5.x8664.rpm. I will use that later on in the process. I put this kernel simply in /root At this point I just start the vm with xm create vm.cfg and start my vnc console to the vm console. Oracle Linux will boot from the iso image, I just go through the install steps and click on UPgrade existing (not re-install). Because the VM is the same as the ISO the install won't actually do anything and it will run through instantly. When the "Reboot" button pops up, don't reboot. Switch to the command prompt console. hi alt-f2 to go to the shell prompt. Now it's easy : umount /mnt/sysimage/boot cd /mnt/sysimage chroot . mount /dev/hda1 (if that was your /boot partition) export PATH=/sbin:$PATH (just to clean that up) edit /etc/modprobe.conf and comment out the xen modules (just put a # in front) Install grub. if your /boot is hda1 then that is (hd0,0) $ grub root (hd0,0) setup (hd0) exit grub now you have a good bootsector, grub installed and you have your grub.conf file Install the new kernel cd root (this is your old /root in your pv image) rpm -ivh remove (or comment out) boot='d' in your vm.cfg restart the VM and you should be good to go, regular grub should start and load your environment. Caveats : this assumes you used labels for your filesystems. if /etc/fstab were to have devices listed then you would have to rename these device before rebooting as well. If you had a /dev/xvda disk then this would be /dev/hda or /dev/sda. All in all it is a relatively short and simple process.

In the case of my VM template it was based on OL5U4 So I downloaded Enterprise-R5-U4-Server-x86_64-dvd.iso and added it as a cd device. disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,xvda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,xvdb,w', ] to disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,hda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,hdb,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Enterprise-R5-U4-Server-x86_64-dvd.iso, hdc:cdrom,r', ] boot='d' for the network devices (vifs) I change : vif = ['bridge=xenbr2,type=netfront'] to vif = ['bridge=xenbr2,type=ioemu'] That should do it. Next, inside the VM, I copy over the regular kernel rpm that I want to end up running in hvm mode. In this example case it was : kernel-2.6.18-164.0.0.0.1.el5.x8664.rpm. I will use that later on in the process. I put this kernel simply in /root At this point I just start the vm with xm create vm.cfg and start my vnc console to the vm console. Oracle Linux will boot from the iso image, I just go through the install steps and click on UPgrade existing (not re-install). Because the VM is the same as the ISO the install won't actually do anything and it will run through instantly. When the "Reboot" button pops up, don't reboot. Switch to the command prompt console. hi alt-f2 to go to the shell prompt. Now it's easy : umount /mnt/sysimage/boot cd /mnt/sysimage chroot . mount /dev/hda1 (if that was your /boot partition) export PATH=/sbin:$PATH (just to clean that up) edit /etc/modprobe.conf and comment out the xen modules (just put a # in front) Install grub. if your /boot is hda1 then that is (hd0,0) $ grub root (hd0,0) setup (hd0) exit grub now you have a good bootsector, grub installed and you have your grub.conf file Install the new kernel cd root (this is your old /root in your pv image) rpm -ivh remove (or comment out) boot='d' in your vm.cfg restart the VM and you should be good to go, regular grub should start and load your environment. Caveats : this assumes you used labels for your filesystems. if /etc/fstab were to have devices listed then you would have to rename these device before rebooting as well. If you had a /dev/xvda disk then this would be /dev/hda or /dev/sda. All in all it is a relatively short and simple process.

Can't boot in Ubuntu after windows upgrade

- by VanceAnce

After my lastest update for Ubuntu and Windows XP, I got a Grub error on booting the next day. ls lists the following (without () ): sd0 sd1, msdos sd2 sd5 sd6 When I tried to get into one with (sd0,xy)/ it doesn't detect system or unknown file system error. I tried to boot to a live session with a Knoppix live CD and found out that all data exists. I also tried to recover with TestDisk and it finds all systems. Here is the test disk result: Start End Size in sectors 1 * HPFS - NTFS 0 1 1 7079 254 63 113740137 2 E extended LBA 7080 0 1 12161 254 63 81642330 5 L HPFS - NTFS 7080 1 1 10266 254 63 51199092 [Schule] X extended 12031 30 1 12161 254 63 2102625 6 L Linux Swap 12031 31 33 12161 254 63 2102530 I've 1 winxp-home, 1x Ubuntu (ext3+swap) and 1 winxp prof and then I wrote on mbr with TestDisk but I always get the same errors with Grub. What should I do? I need both XP and Ubuntu. Help me please. more infos in answers below - sry for thos confusing style but im working on diff live system and browsers and have to reboot always the boot info script output is also down below maybe an advanced user can correct my fail posting - after i can solve my issuse i will register here thanx and pls help me with those weired issues ! as i still cant just comment my own answer or those on top i again has to put it here as a sepperate answer..... (or even edit - maybe an browser failur using the live cds ... cause this posti can edit) here the bootinfo script output - but the result is the same as with TestDisk ... but it looks worse - cause it also doesnt detect my old ubuntu ... but there wasnt a eares process or overwrite process visibile ending the last working session output: Boot Info Script 0.61 [1 April 2012] ============================= Boot Info Summary: =============================== = Syslinux MBR (4.04 and higher) is installed in the MBR of /dev/sda. sda1: __________________________________________ File system: ntfs Boot sector type: Windows XP: NTFS Boot sector info: No errors found in the Boot Parameter Block.

The Raspberry Pi JavaFX In-Car System (Part 3)

- by speakjava

Ras Pi car pt3 Having established communication between a laptop and the ELM327 it's now time to bring in the Raspberry Pi. One of the nice things about the Raspberry Pi is the simplicity of it's power supply. All we need is 5V at about 700mA, which in a car is as simple as using a USB cigarette lighter adapter (which is handily rated at 1A). My car has two cigarette lighter sockets (despite being specified with the non-smoking package and therefore no actual cigarette lighter): one in the centre console and one in the rear load area. This was convenient as my idea is to mount the Raspberry Pi in the back to minimise the disruption to the very clean design of the Audi interior. The first task was to get the Raspberry Pi to communicate using Wi-Fi with the ELM 327. Initially I tried a cheap Wi-Fi dongle from Amazon, but I could not get this working with my home Wi-Fi network since it just would not handle the WPA security no matter what I did. I upgraded to a Wi Pi from Farnell and this works very well. The ELM327 uses Ad-Hoc networking, which is point to point communication. Rather than using a wireless router each connecting device has its own assigned IP address (which needs to be on the same subnet) and uses the same ESSID. The settings of the ELM327 are fixed to an IP address of 192.168.0.10 and useing the ESSID, "Wifi327". To configure Raspbian Linux to use these settings we need to modify the /etc/network/interfaces file. After some searching of the web and a few false starts here's the settings I came up with: auto lo eth0 wlan0 iface lo inet loopback iface eth0 inet static address 10.0.0.13 gateway 10.0.0.254 netmask 255.255.255.0 iface wlan0 inet static address 192.168.0.1 netmask 255.255.255.0 wireless-essid Wifi327 wireless-mode ad-ho0 After rebooting, iwconfig wlan0 reported that the Wi-Fi settings were correct. However, ifconfig showed no assigned IP address. If I configured the IP address manually using ifconfig wlan0 192.168.0.1 netmask 255.255.255.0 then everything was fine and I was able to happily ping the IP address of the ELM327. I tried numerous variations on the interfaces file, but nothing I did would get me an IP address on wlan0 when the machine booted. Eventually I decided that this was a pointless thing to spend more time on and so I put a script in /etc/init.d and registered it with update-rc.d. All the script does (currently) is execute the ifconfig line and now, having installed the telnet package I am able to telnet to the ELM327 via the Raspberry Pi. Not nice, but it works. Here's a picture of the Raspberry Pi in the car for testing In the next part we'll look at running the Java code on the Raspberry Pi to collect data from the car systems.

Take Snapshots of Your Favorite Movie Scenes in VLC

- by DigitalGeekery

Have you ever wanted to grab a screenshot of your favorite TV or movie scene? Today we’ll show you how to do so with VLC Media Player. If you don’t have it already, download and install the latest version of VLC (link below). Start playing your movie, and to grab a snapshot, select Video from the menu and click Snapshot. When you take a snapshot, by default a preview is displayed at the top left and the folder where the file is saved is briefly displayed on the screen. If you enable the Advanced Controls, you can take a snapshot with a click of a button, and advance the video frame by frame to get a more accurate shot. To enable the Advanced Controls, select View and Advanced Controls. You’ll see the Advanced Controls buttons appear below the slider. Now just click on the Snapshot button to grab an image. You can more easily control the frame you wish to grab by pressing the Frame by Frame button. You can pause the movie when it is near the perfect spot for your snapshot, and then press the Frame by Frame button to advance a single frame at a time. By default, the snapshots are saved as PNG files in your My Pictures folder in Windows. You can change those setting in the Preferences. First, you’ll need to select All under Show settings at the bottom. Then click on Video on the left. Scroll down a bit and you’ll see the Snapshot section. Here you can change the format from PNG to JPG, change the directory to which the snapshots are stored, turn on and off the preview, and change the filename prefix. Click Save when finished. Now you have nice screenshots of your favorite movie to display as you wish…such as a Desktop Background! VLC is an excellent media player that runs on Windows, Mac, and Linux. In addition to playing almost any media file, it also makes grabbing screenshots of your videos a breeze. Want to know more about VLC?
