Hard drive resizing a common practice for most of the computer users, who prioritize the effective management of data. Most of the computer operating systems, including Windows and Linux provide inbuilt utilize to manage hard drive partitions. But in some situations, generally in a dual-boot system with Windows and Linux, partition resizing in Windows may damage the Linux partitions and lead to critical data loss situations. In such critical situations, you are required to opt for Linux Data Recovery to retrieve data from damaged Linux hard drive volumes.

Consider the following scenario. You resize your Windows Vista partition using in-built Disk Manger tool to free up some hard drive space. Then you install Linux on the newly created Ext4 hard drive partitions. At last, you create another NTFS file system partition for storing data that you formatted in Windows Vista and end up with a partition scheme that is similar to the following one:

sda1 (primary) Hidden (Recovery)
sda2 (primary) Vista C:\ (NTFS)
sda3 (primary) Linux \ (Ext4)
sda5 (extended) Swap Swap (Swap)
sda6 (extended) Data D:\ (NTFS)

Your systems works properly until you download and install security updates in Windows Vista. After applying the updates, when you boot your Linux system next time, fsck gives you a number of error messages about the multiply-claimed blocks by the Inodes of udev rule files. Udev corruption creates a number of issues with your Linux computer and renders your valuable data inaccessible.

In Linux operating system, udev is a device manage for 2.6 series of kernel. It primarily manges the device nodes in /dev. This is successor of the hotplug and devfs that meas it handles /dev directory and all the user space actions.

In such critical situations, you need to replace the damaged kernel files or even the kernel. It is possible by formatting the hard drive and reinstalling operating system. Although, formatting removes all of the hard drive errors, but also delete all the files from hard drive. In Such scenarios, you require Data Recovery Linux to extract data from formatted hard drive.

The Linux Data Recovery is possible through third-party applications, known as Linux Recovery Software. The tools perform extensive scan of entire hard drive and extract all the data from it. With rich graphical user interface and read-only conduct, the applications are easy and safe to use.

Stellar Phoenix Linux Data Recovery is a comprehensive software to ensure absolute and quick recovery of all your lost data from Ext4, Ext3, Ext2, FAT12, FAT16 and FAT32 file system volumes. The application works will most of the major distributions of Linux operating system including SUSE, Ubuntu, Red Hat and Fedora.

Are you resizing your Linux hard drive partitions using Gparted utility? Create an absolute backup of your valuable data before your proceed. Gparted provides you advanced and easy methods to perform a number of operations on your Linux volumes. However, in some cases, re-sizing the partition with Gparted utility can become very problematic. It may corrupt the volumes and cause critical data loss situations. In order to recover lost data in such circumstances, Linux Data Recovery becomes need of hour.

Gparted is an inbuilt tool in Linux operating system, which enables you to create, resize, deleted, copy, move, or check hard drive partitions, and file systems on partitions. It also creates partition table on hard drive and enables/disables the partition flags like hidden and boot. It is helpful for reorganizing disk usage, creating space for new OS, mirroring one volume with another, and copying the data stored on hard drive.

Sometimes, while resizing the Linux hard drive partitions through Gparted tool, the process may gets terminated with read/write errors. After this alarming incident, hard drive doesn’t mount at all and gives you further errors.

At this point, if you run the fsck utility after restarting the problem remains intact. Furthermore, you encounter further error messages. The situations keep getting more and more serious at every attempt of solving this problem. Linux superblock may get damaged, and give you the indication of file system corruption.

The problem can be indicated by various error messages, such as:

“Superblock corrupted, run with -b 32768″

Some warning messages may also occur, which indicates the the device is busy and it cannot be accessed.

Redundant copies of the superblock are maintained by Linux file system. You can fix this issue by using any of such copies. You can search alternative superblock using “mkfs -n” command.

However, if you cannot find a superblock that is free from corruption, you need to format the hard drive and reinstall operating system. Although, this method can fix up the problem, but also removes all the data from hard drive and creates need of Data Recovery Linux.

You can recover Linux data with the help of third-party Linux Data Recovery software. The applications enable you to perform Linux Recovery on your own as they have simple graphical user interface.

Stellar Phoenix Linux Data Recovery is the most advanced and widely used application to perform absolute recovery of lost Linux data. It works well with all major distributions of Linux operating system, such as Red Hat, Debian, SUSE, Fedora, and Ubuntu. The software recovers lost data from Ext4, Ext3, Ext2, FAT32, VFAT, FAT16, and FAT12 file system volumes.

The hard drives can be divided in one or more parts, known as partitions. The division of hard drive is described in partition table, stored in sector 0 of hard drive. Linux operating system requires at least one hard drive partition, namely for the root file system. It may use the swap files and swap partitions, however the latter are quite efficient. Thus, generally you may want second Linux hard drive partition devoted as the swap partitions. In some cases, improper use of hard drive management tools can cause data loss and need Linux Data Recovery to be sorted out.

On the Intel hardware, the BIOS (Basic Input/Output System) that boots up your system and can generally only access first 1024 cylinders of hard drive. Due to the same, you may need to create third hard drive partitions if your hard drive is large in size. This partitions is generally mounted on the /boot , for storing kernel image and some auxiliary files required at boot time, so that BIOS can access them.

You can create the manipulate the partition table in Linux using a menu drive program, known as fdisk. However, this tool can not understand the GPT (GUID Partition Table) and is not work with large partitions. Fdisk understands DOS partition table and BSD/SUN disklabels.

The Fdisk automatically obtains the hard drive geometry, if possible. It is not inevitably physical disk geometry (as modern hard drive don’t actually have physical geometry), but is disk geometry that is used for DOS type partition tables.

Generally everything works fine if only the Linux operating system is installed on your drive. But, in dual-boot configuration, you should let the Fdisk from other operating system create at least one partitions. While booting the Linux operating system, it considers partition table and attempts to derive what geometry is needed for effective cooperation with another operating system.

Before you proceed for any operation on your hard drive, it is recommended to create complete backup of your significant data. When you backup data using dd command, you need to be careful. A minor mistake may cause severe data loss and need Data Recovery Linux to be handled.

Linux Data Recovery is possible with the help of powerful third-party tools, known as Linux Recovery Software. The applications are particularly designed to carry out thorough scan of the drive and extract lost, missing, and inaccessible data from it.

Stellar Phoenix Linux Data Recovery is the most advanced tool for absolute recovery. The software recovers data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes. It is compatible with all major distributions of Linux operating system including Red Hat, Debian, SUSE, and Fedora.

Booting errors are very common in Linux operating system, which makes your system unbootable and unusable. The errors prevent your system from booting and render it totally inaccessible. They prove to be a big threat to your precious data. Such errors usually occur after unexpected system shutdown and hard drive data structure corruption.

Losing data from hard drive in such situations creates big problems for your business. So, you need to restore data from the latest backup to prevent data loss. However, in case backup is not updated or available, Linux Recovery solutions come to your help.

When you face boot errors, your Linux system refuses to boot properly. There are various types of boot errors, depending upon the type and cause of failure. One such error is SCSI CRC error. You may come across the below error message when your Linux operating system loads:

“Creating Root Device

mounting root filesystem

(scsi:0:0:0:0) CRC error during data-in phase

(scsi:0:0:0:0) CRC error in intermediate CRC packet

scsi: aborting command due to timeout: pid 0, scsi 0, channel 0, id 0, lun 0 read (10) ……”

The above error halts Linux boot process, making your hard drive inaccessible. To retrieve lost data in such cases, identify the problem and perform Data Recovery Linux by resolving it.

Cause

On the first appearance, this issue seems to be associated with hardware problems, but this is not the case. You may face this behavior due to any of the below reasons:

• Damaged or missing /boot directory from Linux operating system installation.

• File system error or corruption.

• Missing or corrupted initrd.

/boot directory is a major component of Linux operating system, which contains critical information about booting parameters and process. While initrd is a temporary data structure, which makes preparations before mounting of root file system.

Resolution

Use Rescue CD of Linux operating system to overcome this problem by restoring damaged /boot directory and initrd. When it fails, go for Linux Data Recovery software to retrieve lost data.

The Linux Data Recovery applications are able to scan damaged Linux hard drive and extract all lost data from it. They have read-only conduct on the drive to ensure safe recovery, without modifying original data on the disk.

Stellar Phoenix Linux Data Recovery is the most comprehensive and advanced utility to ensures absolute recovery of lost data. The software works well with all major distributions of Linux operating systems, such as SUSE, Debian, Red Hat, Ubuntu, and Fedora. It recovers data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.

When the Reiser FS kernel detects an error on the hard drive, it prints some error messages on the screen. It might be a bug. In the Super Block of Reiser FS file system, there is an Error pasture. It is set when file system kernel notices something bad.

So, what happens in this case? May be the Linux user could not read Syslog and could not see the error message or the error is simple an overture of memory corruption, which could lead system to crash.

In such situations, when you reboot the system, this goes in the merry way, mounting Reiser FS file system with known errors on the same, using badly allocated memory locations, B-trees and directories etc. Double allocation of memory blocks and overwriting of blocks may also take place, making the files corrupt.

The final result of this whole problem would be the severe file system corruption. At this point of time, it becomes completely impossible to fix the file system errors for the user. No disk repair utility can detect the errors.

In even the worse scenario, the Reiser FS read Super Block code overwrites the Super Block at mount time. It makes the situations worse and the file system totally useless. After crash, you might come across the following error messages:

“S->u.reiserfs_sb.s_mount_state = SB_REISERFS_STATE(s);

s->u.reiserfs_sb.s_mount_state = REISERFS_VALID_FS”

In these grave situations, if you continue using system, the problems may become more terrible. The ultimate results of this whole mishap would be the loss of your critical business as well as personal data stored on your Linux hard drive.

At this point of time, the only thing which can save you from going out of business is data recovery Linux. It is the way out to retrieve all of your lost, missing and inaccessible data from logically failed Linux hard drive.

Data recovery Linux can be easily effectively and completely performed with the help of Linux data recovery software. Linux recovery software are easy to use tools, which systematically scan your affected Linux hard drive and extract as much data as possible.

To ensure trouble-free, safe and quick Linux data recovery, it is extensively important to purchase a highly developed and influential data recovery Linux tool. A Linux recovery software of trusted brand will give you the best data recovery Linux results.

In Linux operating system-based computer, the Cluster Management tool or Cluster Manager is used to manage the user nodes. This is a command-line or GUI tool, which works on one or multiple cluster nodes. It works together with the cluster management agent. It has various subsystems and CMAN is one of them.
To manage the cluster management subsystem CMAN, cman_tool program is used. But in case if you use incorrect command or switch with this utility, all cluster nodes may get affected and data loss situations arise. In order to retrieve data in these circumstances, Linux Data Recovery solutions are required.

The cman_tool could be used for joining the nodes to cluster, kill another cluster node, change value of the expected votes of cluster, and leave the cluster. You should be careful while using this application and must understand the consequences of commands issued through cman_tool. They might affect all the nodes in cluster. In most of the cases, this program is invoked by the shutdown and startup scripts. The cman_tool uses various subcommands, which include the following:

Join- It is the major use of the cman_tool. This utility instructs cluster manager to try to join the existing cluster or form a new cluster (if there is not existing cluster). If you do not give any option to the command, it would take cluster configuration information from Cluster Configuration System (CCS).

Kill- Tells the CMAN to kill another node in cluster. It would cause local node to send “KILL” message to the node and it would shut down. If the node had failed, recovery would occur.

Leave- Tells the CMAN to leave cluster. You can’t do it if the subsystems (like GFS and DLM) are active. You need to shutdown CLVM and dismount all the GFS

file systems before using the cman_tool leave. Before applying the force command with this option, you should create backup of all your valuable data as it might cause critical data loss situations and need Data Recovery Linux to handle it.

Linux Recovery is potential through powerful third-party applications, known as Linux Data Recovery software. They use extensive scanning techniques to thoroughly scan whole hard drive and extract all of your valuable data in most of the data loss situations. They have simple graphical user interface and thus do not need sound technical skills to retrieve data.

Stellar Phoenix Linux Data Recovery is an effective tool to ensure absolute recovery in the majority of data loss situations. It supports recovery from Ext4,Ext3, Ext2, FAT32, FAT16 and FAT12 file system volumes. The software works well with all major distributions of Linux including SUSE, Red Hat, Mandriva and Ubuntu.
