All the data files that are accessible in Linux based computers are placed in a big tree, called root directory and denoted as ‘/’, in an organized form. These data files might be spread out over various devices. The mount command in Linux operating system allows you to attach a file system on a data storage media to the root directory. However, if the file system is faulty and you run fsck utility to fix the problem after mounting the disk using this command, severe file system corruption occurs. It causes critical data loss situations and calls for Linux data recovery.

The mount command tells the Linux kernel to attach the file system found on your hard drive volume in the /dir directory. The previous owner, mode, and contents of the directory become invisible after mounting, and as long as the file system stays mounted, the /dir pathname refers to the root of file system on Linux hard drive volume.

The following three types of invocations of mount command don’t actually mount the volume:

·     mount -h- It prints the help message on screen.

·     mount -V- This invocation prints the version string.

·     Mount [-l] [-t type]- The option lists all the mounted file systems that are of type “type” on your Linux hard drive. The -l option adds labels (like ext2, ext3) in the listing.

In current versions of Linux operating system, it is possible to mark the mount and submounts as private, shared, unbindable, or slave. The shared mount gives you an option to create mirrors of the mount.

Mount is an essential process for accessing data from any Linux hard drive volume. If the drive is not mountable, it cannot be accessed. Sometimes, when you try to mount a Linux volume, you come across the following error message that puts you in need of data recovery Linux:

“Wrong fs type, bad option, bad superblock on /dev/hda8, missing codepage or helper program, or other error. In some cases useful info is found in syslog – try dmesg | tail or so”

This problem is caused by dirty or corrupt file system. In such cases, you need to use Linux recovery software to get your mission-critical data back. The Linux data recovery applications enable you to thoroughly scan the affected Linux hard drive using advanced scanning algorithms.

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

Linux operating system is popular for its robustness and advanced features. Like every other operating system, Linux has its own style of naming different features and here, volume means the logical partition of the hard drive. A hard drive is divided into several logical volumes for a number of reasons such as multiple operating systems, keeping different categories separately etc. Though multiple hard drive volumes have many benefits, sometimes, the volumes get deleted, corrupted or inaccessible leading to the cases of huge personal as well as professional loss of data. Under such cases, you need to take the help of Linux data recovery to recover back your valuable data.

Different partitions or volumes are loaded with different file systems and in Linux these volumes are dealt by a logical volume manager. Every day, as we deal with many different kinds of data under different hardware and/or software environment, it is impossible to completely avoid data loss situations. Following are the reasons that can trigger the loss or inaccessibility of the logical volume:

• Virus attack or malware intrusion leading to corruption.
• Accidental or intentional deletion of partition/volume.
• Heavy power surge leading to file system corruption.
• Operating system malfunction etc.

All the above situations lead to the loss or inaccessibility of your valuable Linux data. As, data loss is quite inevitable it is always advised to take regular backups and moreover, it is suggested to automate the backup process. But, it is not always possible to take backup of almost every piece of data and as, data loss events can accidentally happen at anytime, such data loss situations have always been a nightmare for many. However, the good thing is that any seemingly lost data can be recovered, until those are being overwritten by some other data. Above all, with the invention of technology like Linux data recovery, all your lost, deleted and even formatted Linux data can be recovered safely.

Linux data recovery applications are quite handy are designed with rich graphical user interfaces. The incorporated powerful algorithm and stepwise instruction set make enable the novice users user to without much hardship.

Stellar Phoenix Linux Data recovery is a wonderful Linux recovery utility that enables users to locate and recover seemingly unrecoverable data irrespective of the data loss situations. The software is capable of recovering lost, deleted, formatted or inaccessible Linux data from et2, ext3, ext4 and FAT file system based volumes and is compatible with almost all available Linux flavors and version.

The Linux operating system is supposed to be the most regularly updated operating system among its counterparts. Apart from this fact, for its advanced technology and features, a large number of users prefer Linux. But, in Linux, the user can not get everything preloaded just like Windows. There is an unique command for each operation in Linux and from the long list of regularly used commands, the ‘mount’ command lets the operating system to learn about the file system and lists in the file system hierarchy of the computer, which lets us access the the particular drives. However, sometimes, the ‘mount’ command fails to work and the OS can not be able to learn the drives resulting in the inaccessibility of them. In such situations of data loss or inaccessibility, Linux data recovery can help you recover your valuable data back.

There can be a possible file system corruption, which has led this abrupt behavior of the Linux system following the failure of the ‘mount’ command. The ‘fsck’ is a built-in command-line utility in Linux operating system, which checks the consistency of the file system and repairs the same, if finds any error. After encountering the above situation, if you try to mount the drives using the ‘fsck’ command, you may encounter some more error messages. The error messages may be read as below:

“[/dev/mapper]fsck -a /dev/mapper/mpath0p1
fsck 1.35 (28-Feb-2004)
ext2fs_check_if_mount: Input/output error while determining whether /dev/mapper/mpath0p1 is mounted.”

OR

“fsck.ext2: Bad magic number in super-block while trying to open /dev/mapper/mpath0p1
/dev/mapper/mpath0p1:
The superblock could not be read or does not describe a correct ext2
file system. If the device is valid and it really contains an ext2
file system (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>”

The above error messages clearly state that the file system has been corrupted. In order to resolve the issue, you need to boot the Linux system from the safe mode and run the ‘fsck’ command to repair the corruption. However, if the file system has been severely corrupted, ‘fsck’ simply exits without doing anything. In such a case, if you are an expert user, you can input the next super-block address or the size of the same to the ‘fsck’ command, which can help the utility to gather the information from the next super-block and do the job.

However, failing to the above resolution method, you need to opt for any Linux drive recovery software to bring back your precious data.

Stellar Phoenix Linux Data Recovery is an efficient as well as 100% risk-free Linux recovery utility of the current time. The utility has been trusted by a number of users for its power-packed scanning algorithms and ability to recover lost, deleted, formatted or inaccessible data from any troubled Linux drive irrespective of the complexity of the data loss situations.

Linux is an open-source operating system that has various distributions, which include Fedora Core. It is an OS, which enables you to access latest open source applications. The OS uses a disk structure similar to various other Linux distributions and may face the same problem of corruption as others do. Corruption makes it inaccessible and unbootable, causing severe data loss. In such critical situations, you are required to opt for Linux data recovery solutions to get your valuable data back.

In a practical instance of the disk structure corruption in Fedora Linux OS, you may encounter the below error message when you reboot the Fedora operating system-based computer after it freezes at startup-

“EXT-fs: dm-0: couldn’t mount because of unsupported optional features (2000200)
mount error 22 – mounting ext 3″

Subsequent to the above error message, you might get further error message that says-

“kernel panic – not syncing: Attempting to kill init.”

After this error message, Fedora operating system cannot detect and access Linux hard drive partitions when you try to perform data recovery Linux using Linux Rescue CD. When you try mounting the disk manually, it says that the disk has invalid arguments and thus it cannot be mounted.

Grounds of the problem
As stated above, this problem occurs due to corruption to the logical structure of the Linux hard drive. It may also occur if disk data structures, like Superblock and file system, are damaged. Corruption might be the outcome of virus infection, improper system shutdown, operating system malfunction, and other similar reasons.

Resolution
Use any of the below Linux recovery solutions to sort out this problem-
Boot your Linux computer using the Rescue CD and then run pvscan command for checking the logical volumes.
Run fsck -C -y /dev/hdXX command.

If none of the above Ext2 recovery methods work, you are required to format the disk and reinstall operating system. Although, formatting can fix all disk related problems, but it also cause serious data loss. In such situations, Linux File recovery software are required to retrieve lost data after formatting.

.You are frequently encountering the rebooting of your Linux system and hangs frequently.
.Getting an error message, such as: “No Fixed Disk Present” or “DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER”.
.On start-up receiving error message, such as: “Operating system not found” or “Drive not formatted”.
.There can be a number of possible causes, for which you are encountering the above mentioned situations of data loss or inaccessibility from your Linux system. To name a few, below are some serious and complex causes behind hard drive crash:
.Corrupted or damaged Master Boot record(MBR).
.Deletion or missing of necessary system files.
.Corruption to the superblock of the hard drive.
.Corruption to the file system of the Linux hard drive.
.Deadly boot sector virus or malware infection.
.In all the above data loss situations, first of all, you can try repairing your operating system by running the operating system CD. However, if you do not get any positive result out of it, try the ‘fsck’ command-line utility, which is meant to locate any file system based errors and fix them.

In case, you are still unable to resolve the issue, you have to format the hard-drive and make a fresh installation of the operating system. As formatting will erase all the data from the Linux hard drive, you have to restore them from a valid backup. If backup is unavailable, you have to use any Linux drive recovery utility to bring the lost/formatted data.
