Most commonly, the problem occurs due to missing or corrupt data structures of your Linux hard drive. Due to the same, the operating system can not locate stored files on the hard drive and access them. At this point, you need to opt for Linux data recovery solutions to get your valuable data recovered.

Symptoms that indicate the crash of a Linux hard drive: Such symptoms include the following ones:

• Your Linux operating system-based computer does not boot up.
• You encounter various error messages, such as “No Fixed Disk Present” or “DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER”
• Black or blank screen after you power up your system.
• System reboots, freezes, or stops responding frequently.
• “Operating system not found” and “Drive not formatted” messages.

Hard drive crash can be caused by various reasons and renders entire system inaccessible. The most common reasons of Linux hard drive crash are as given below:

• Boot sector virus or damaged MBR (Master Boot Record).
• Corrupted or damaged file system of Linux hard drive.
• Missing or damaged system files or operating system.
• Virus infection.
• Corrupt Superblock or other critical meta data structures.

In order to fix a crashed Linux hard drive and perform Data Recovery Linux, you are required to format it and reinstall operating system. This process replaces all the missing, corrupt, or damaged system resources and brings the hard drive back to life. However, it also removes all the data from hard drive and create needs of Linux recovery.

The best possible way is to recover i.e. recovery, and efficient commercial software, known as linux recovery software. They use high-end scanning techniques to carry out in-depth scan of entire Linux hard drive to extract all lost data from it.

A new cloud filesystem, called Ceph, is one of the most significant additions. It is a distributed network filesystem that is designed for massive scalability, capable of managing petabytes of storage. The underlying technology has some novel characteristics, such as an adaptive metadata storage framework that can automatically redistribute information about the filesystem hierarchy across the storage nodes in response to fluctuations in demand. However, the developers warn that the project is still largely experimental and isn’t ready yet for deployment in production environments.

Developer Sage Weil in a kernel mailing list post wrote, “Although stability has improved greatly in the last few months, Ceph is still relatively new and experimental for something as conservative as storage, and only time and testing will change that”. “Getting the code upstream sooner rather than later will accelerate that process by reducing barriers to testing, expanding the pool of systems with a usable client, and making it easier for distros to include it.”

LogFS, a log-structured filesystem that is intended for use on flash storage devices, is another major addition. It is designed to replace the kernel’s Journaling Flash File System v2 (JFFS2), but is best-suited for larger flash storage devices. It is said to offer a reduction in mount time and memory overhead relative to JFFS2.

A number of other noteworthy improvements are present in the .34 release. Suspend and resume performance get a boost from a parallelization effort. Networking in KVM gets performance improvements too, thanks to the vhost net drivers.

Consider, you have accidentally run fsck on a mounted Linux OS. The inode root gets damaged and all inodes start calling similar blocks. When you try to mount the volume after fsck, the following error message is discovered:

“Mount: wrong fs type, bad option, bad superblock on /dev/hda1, missing codepage or helper program, or other error. In some cases useful info is found in syslog – try dmesg | tail or so”

When you run \dmesg\, as suggested in the error message, another error message may be displayed, that is:

“ext3-fs: corrupt root inode, run e2fsck”

And when you run e2fsck, yet another error message is displayed, that is:

“Root inode is not a directory. Clear?”

Once you press ‘Y’ and proceed with the process, the parent entry of each inode from the root directory will be deleted. The root inode will attempt to recover but if it fails, another error message will be displayed, that is:

“Cannot Allocate Root Inode”

After this error message, you will not be able to access your system.

Reason: This behavior is caused due to corruption of the file system, superblock, root inode, or any other Linux data structure. Because of this, the OS cannot locate the hard disk volumes.

Solution:

In order to sort out this problem and perform Linux data recovery, you should reformat the hard disk and reinstall the Linux operating system. However, that would invariably mean that your valuable data will be lost.

In such cases, you should use a third-party Linux recovery to recover lost data. Such tools are able to Recover Linux data safely by using fast yet sophisticated scanning algorithms.

PTS Desktop Live 2010.1, codenamed “Anzhofen,” a live DVD distribution designed solely to run the Phoronix Testing Suite, has now been released, bringing the comprehensive benchmarking and testing software suite to those that want the most accurate results.

Like previous releases, it’s based on the popular Ubuntu Linux distribution and PTS Desktop Live 2010.1 comes with the latest Phoronix Test Suite 2.4.1. The idea is to give users a standard software stack to run the testing suite ensuring that the underlying operating system doesn’t interfere with the validity of the results.

Highlights of PTS Desktop Live 2010.1:

• Custom Linux Kernel 2.6.33 Release Candidate 6;
• Based on the latest Ubuntu 10.04 LTS Lucid Lynx packages;
• 43 tests from the Phoronix Test Suite 2.4.1;
• Stripped-down version of GNOME 2.29;
• Designed for relatively modern hardware.

It requires:

• Modern 64-bit AMD or Intel processor;
• 2GB of RAM;
• An ATI, NVIDIA or Intel graphics card;
• Internet connection.

Phoronix has gone to great lengths to ensure that PTS Desktop Live 2010.1 squeezes every last ounce of performance out of the PC and that all unnecessary components are removed. As such, the developers have put the Linux Kernel 2.6.33 on a diet, taking out support for older hardware and platforms and the Anzhofen 2.6.33-rc6-phx10 kernel weighs in at just 16 MB, being some 40 percent smaller than the vanilla Linux Kernel in Ubuntu, Phoronix says.

The developers warn that this means that you’ll likely need a machine not older than two or three years to ensure that everything works. Continuing with the minimal design, PTS Desktop Live 2010.1 comes with just a customized GNOME 2.29, a web browser and a text editor and, obviously, the newly released Phoronix Test Suite 2.4.1.

The next release, PTS Desktop Live 2010.2 (codenamed “Rottbach”), is expected to land at about the same time as the upcoming Phoronix Test Suite 2.6, in May 2010. A version of the live OS designed with netbooks in mind, PTS Netbook Live 2010.1, should be coming soon.

For the year 2010, the PapugLinux 10.1 is the major release in a little over a year and likely the only one for 2010 based on previous release schedules. PapugLinux 10.1 is mostly aimed at bringing the various software components up-to-date, though version numbers aren’t, for the most part, the newest ones.

In terms of package update and hardware support, Version 10.1 is a major release of PapugLinux. The latest version of X server will allow you to enjoy PapugLinux at the best capacity of your hardware.

PapugLinux 10.1 comes with a very short list of default applications installed with just the bare-bone functionality covered. The latest version updates the X-Window server to X.Org-7.4 (the latest stable release is 7.5). Mozilla Firefox 3.5.6 is included as the default web browser; email is handled by Sylpheed 2.6.0. and instant messaging by Pidgin 2.6.3.

For simple office tasks, the AbiWord 2.6.4 word processor and the Gnumeric 1.8.4 spreadsheet editor are also included. On the server side, PapugLinux 10.1 comes with the Apache 2.2.14 web server, the latest version, the Cups 1.3.11 print server and the ProFTP 1.3.2b FTP server.

PapugLinux 10.1 uses the Rox 2.9 file manager/desktop environment with a few customizations for better integration. The distro is designed as a Live CD that should run on even the oldest x86 hardware, but it can also be used as a stand-alone hard drive install.

No password is required, as the user ‘papuglinux’ is the default operating user. System user ‘root’ can be used by advanced users, the password has been set to ‘papuglinux.’ If you have 512 MB of RAM, try ‘linux copy2ram’ as boot option.”

For software platforms on cellphones, the market is led by the Nokia’s Symbian operating system, but it has lost much ground over the last year to Apple Inc and Research in Motion, maker of the BlackBerry.

Linux, the computer operating system, is starting to win traction with Google Inc using Linux to build its Android platform, and Nokia rolling out its top-of-the-range model N900 using Linux Maemo.

According to head of LiMo, Morgan Gillis, there has been a step change for Linux in mobile. No other operating system now matches the vendor coverage of Linux — it is being commercially deployed by virtually all leading mobile device vendors from the largest downwards.

LiMo, a non-profit foundation, hopes to benefit from its focus on giving greater say over software development to telecoms operators.

The role of top operators in the platform – Vodafone uses it in its 360 offering – is a key attraction for Adobe, whose Flash is among the world’s most widely used web-based computer programs, and it has some 1.6 million developers.

Vodafone and other operators have strongly pledged for a smaller number of operating systems, as supporting them is a timely and costly exercise. However, in recent years, the number of large operating systems has increased, with new players like Apple and Google entering the mobile market.

In a latest twist Samsung Electronics — the world’s second largest handset maker and one of the key members of LiMo – unveiled in late 2009 its own smartphone platform.

Linux is the most popular type of free or so-called open source computer operating system which is available to the public to be used, revised and shared. Linux suppliers earn money selling improvements and technical services, and Linux competes directly with Microsoft, which charges for its Windows software and opposes freely sharing its code.

Japanese electronics firms NEC and Panasonic, and Israeli firm Else unveiled on Monday a total of seven new phones running on LiMo software.

On Thursday, the organization announced that OpenOffice 3.2 is now available for download.

The latest version of the productivity suite- which is intended to be an open-source alternative to Microsoft Office- boasts faster start-up times, ODF support, proprietary file support, support for postscript-based OpenType fonts, and more.

The release comes after OpenOffice.org hit a milestone of 300 million downloads over the course of its 10-year history, 100 million of which occurred from the organization’s main Web site.

The suite includes basic components like word processor, spreadsheet, presentation, graphics, and formula and database capabilities. Improvements to those components the version 3.2 boasts, including the Calc spreadsheet. The Chart module, meanwhile, received a “usability makeover” and includes new chart types.

Some people are currently locked in to other personal productivity tools – maybe by corporate IT policy, or by tie-in to other legacy software. For everyone else, we want OpenOffice.org to be the 2010 office software of choice, and 3.2 takes us another step towards that goal,” said Florian Effenberger, marketing project lead of OpenOffice.org.

Version 3.2 is available for download on the organization’s Web site.

Cloudcat is a virtual image for developers and quality assurance persons to build and test connected Web applications in the cloud, which is available on the Amazon Web Services and GoGrid cloud platforms, according to MuleSoft.

Also, IT operations can expand data center capacity by using Cloudcat during peak times or as a cheaper alternative to hosting Tomcat on an internal server.

MuleSoft expects Cloudcat will initially be used mostly for development and testing as well as for deployment of certain classes of Web applications.

MuleSoft vice president of business and corporate development, Chris Purpura said, anything that runs on a Java servlet container can be deployed on Tomcat, and these are typically lighter-weight Web applications that need good scalability” and varying levels of customer demand.

Purpura also added, the application can take the advantage of elasticity by putting them in the cloud. However, Tomcat is not an enterprise Java server; it lacks the full Java stack. He said, you probably won’t deploy your Siebel application on Tomcat.

Features of Cloudcat include:

• Provisioning of Cloudcat for developing and testing Tomcat applications.
• A familiar deployment model in which applications are put on Cloudcat just as they would on a local Tomcat server.
• Diagnostics of the Cloudcat runtime and MuleSource Tcat Server management console.
• Integration with the Apache Maven Java repository, for integration between development and testing.
• Integration with Tcat REST APIs for management and controls.
• Enterprise support.
• Inclusion of the MySQL database on Linux.
• 32- and 64-bit images.

The price of Cloudcat Amazon Edition starts at 30 cents per hour and features Canonical Ubuntu Linux. Cloudcat GoGrid Edition starts at $29 per month, featuring Red Hat Enterprise Linux.
