When you start any application on your Linux system, you may come across with the following error message:

“Program name: error in loading shared libraries: lib xxx…so. X: cannot open shared object file: No such file or directory.”

After this error message, the application gets terminated unexpectedly and you can not use it any more.

Reason of this problem

This problem occurs with the applications which are using shared libraries. This problem occurs if your computer has incompatible libraries to the applications or the applications and system have mismatched file versions of libraries.

Another reason of this problem could be the corruption to system files. The corruption could be the result of virus attack. Due to corruption, the application could not access the required files and fails to start.

Regardless of the reason, this error message leads to the inaccessibility of your precious data stored on the hard drive and ultimately leads to data loss. For savin your business critical data, it is extremely important to solve this issue as soon as possible.

Resolution

To work around this issue, you can use the following two options:

? If the problem is due to incompatible application or system libraries, update them.

? If it does not work, the problem is due to system file corruption and it needs to reinstall the operating system.

Reinstallation of operating system is the ultimate solution of all the system related problems. But it also has a downside which can lead to data loss. Reinstallation requires hard drive formatting and formatting wipes all the data stored on the drive.

In these situations, you need for something which can perform data recovery Linux to recover your lost Linux data. The data recovery Linux is feasible with the application of Linux recovery software.

Linux data recovery software are the perfect solutios of Linux recovery. They can carry out data recovery Linux in all cases of data loss. These software are highly developed and do fast and effective Linux data recovery.

Stellar Phoenix Linux Data Recovery software is the best ever made and highly developed Linux recovery software. This software is applicable to each and every case of data loss and executes efficient data recovery Linux.

You can use this Linux data recovery software for all flavors of Linux to recover all sorts of lost files including documents, spreadsheets, library files, application data and many alike. User interface of this Linux recovery software is very cool looking and thus allows you to have trouble-free data recovery Linux.

Sometimes when you try to install device drivers on your Linux system, you might fail to do it. It could be due to incompatibility of the operating system Kernel with your device driver or device.

To work around this issue, you need to install the latest version of Linux kernel. It may include ‘forcedeth’ patch, which is capable of resolving most of the incompatibility issues.

In some cases, after installing the latest version of Kernel, when you reboot the Linux system, you might face the following error message:

“fsck.ext2: No such file or directory while trying to open /dev/hda8. The super block 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 super block is corrupt, and you might try running e2fsck with an alternate super block: e2fsck -b 8193 fsck failed.”

After this error message, neither the system boots nor any file can be accessed.

Grounds of the issue

As stated in the error message, this problem generally occurs due to super block corruption or file system corruption.

è Super block and file system are two most important data structure of Linux system. Proper functioning of both these is required for ensuring effective working of the system.

After corruption, the operating system could not locate the file and thus can not retrieve it.

Resolution

To work around this problem, you need to install a fresh copy of super block and file system. It is possible through formatting of the hard drive and reinstallation of operating system.

Though, it will remove the errors but will also erase all the data stored on your hard drive. It is the worst scenario of data loss and needs Linux data recovery to get it fixed.

Linux data recovery is feasible with the application of third party Linux recovery software known as Linux data recovery software. Linux recovery software is easy to use and thus allow you to have simple and fast data recovery Linux.

Stellar Phoenix Linux Data Recovery is the most advanced Linux recovery software offered by the data recovery giant- Stellar. This data recovery Linux software works well in all data loss cases and allows Linux data recovery for all sorts of files.

Stellar Phoenix Linux Data Recovery software is powerful enough to carry out efficient scanning of entire hard drive and extract all lost data from it. The user interface of this software is very interactive and thus does not require any sound technical knowledge from users’ side.

Superblock is the most significant component of a Linux volume that restrains critical information about files and folders in file systems as ext2, ext3 and more. It enables us to mount and access the file systems. Superblock corruption primarily occurs due to metadata structure damage, file system corruption, unexpected system shutdown, malicious software like virus and more.

In most cases of superblock corruption, the volume becomes unmountable and the data becomes inaccessible. In such situations, you can restore the lost data using an updated backup. However, if you have not maintained any backup or it is not up-to-date, then you need to recover your data by using advanced Linux Data Recovery tools.

Consider a practical scenario, when you attempt to boot your Linux system, you encounter the below error message:

“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”

After running dmesg tail, you encounter the below error message:

“Couldn’t mount because of unsupported optional features (2000200)”

After the above error message appears, the system becomes unmountable and data stored on the hard drive volume becomes inaccessible. Additionally, you encounter the same error message each time you attempt to boot your system.

Cause:

The main reason behind occurrence of the above error message is superblock corruption.

Resolution:

To resolve the problem and access all inaccessible data, you need to follow these steps:

1. Boot your system by using an alternate block by running the below command:

e2fsck -b 98304 /dev/hdb8

2. Once the file system gets restored to the point at which it can be mounted, you need to fix it by using this command:

e2fsck -c /dev/hda8

-c parameter checks for the bad blocks

However, if the above steps are not able to resolve the issue, you should consider reinstalling Linux. A clean Linux reinstall will erase all existing data from the selected volume. For complete recovery of lost data, you should use efficient Linux Data Recovery software.

Such Linux Recovery tools incorporate effective scanning algorithms to recover all your lost data. These recovery tools provide highly graphical user interface that makes them easily understandable without prior technical knowledge. These tools recover data post situations like superblock corruption, group descriptor faults, inode table damage and more.

Stellar Phoenix Linux Data Recovery is the foremost Linux Recovery tool. It supports recovery from Ext2, Ext3 and ReiserFS file system based Linux volumes. This Data Recovery Linux tool gets installed on Windows (Vista, XP, 2003 and 2000) and the affected Linux drive is connected as slave.
