How to deal with error of shared library

While working in a Linux system, sometimes you fail to start applications or even face problems in accessing the files associated with some applications   following error messages related to various library functions. Such issues occur due to the corruption, damage or deletion of library files, which are necessary for the applications to run. In order to resolve these issues, you need to replace the damaged library files with the good ones and may encounter data loss thereof. Such instances of data loss can only be dealt with any powerful Linux data recovery software.

The error message that you encountered, in case of a damaged library file can be read as below:
“Program name: error in loading shared libraries: lib xxx...so. X: cannot open shared object file: No such file or directory.”
Once, you encounter the above error, the corresponding application terminates or hangs in the middle and can not be run further.
The prime cause behind the above problem is the corruption or damage of the library files, which happens because of the operating system malfunction, virus/malware infection, unexpected system shut-down etc. However, sometimes, the above problem may have occurred due to the missing or corruption of the system files.

Resolution:

Try updating the system libraries, and check whether that solves the issues.
If with the above process, you can not be able to resolve the issue, you need to reinstall the operating system in order to replace the damaged or missing system files. 

If you do have a single Linux partition, with the re-installation of the operating system all your data from the drive will be lost and you need to restore them from a valid backup, failing to which, you have to take the help of a Data recovery utility to recover back your formatted Linux data.

Linux drive Recovery applications are safe, reliable and powerful utilities to find out all your lost, deleted or formatted data from the Linux hard drive and restore them back. The recovery steps with these software can be understood by all as they come with detailed instructions for each step.

Linux Data Loss Caused by Block Group Descriptor

Ext3 or the third extended file system is the most popular file system with many Linux distributions. Ext3 is a journaled file system and stores data by dividing the Linux hard drive into different blocks of bytes. Furthermore, the blocks are managed in block groups and all the information about each block group is defined in the Group Descriptor. Moreover, the information is indexed in the group descriptor table. In case, if the block group descriptors get damaged, the whole Linux system becomes inaccessible and you have to run any Linux data recovery software to recover the data back.

In the situations, when the group descriptor table has been corrupted, you may encounter error messages suggesting the same, following which the Linuxsystem fails to boot. The error message may read as below:

“EXT3-fs error: ext3_check_descriptors / group descriptors corrupted”
When you boot your Linux system, the operating system fetches the information from the Group Descriptor Table and thereby you manage to access the data from various system locations. Hence, when the Group Descriptor gets damaged, the operating system even fails to start-up, as the entire file system becomes unavailable.

The reason behind the corruption can be anything including a virus/malware attack, application malfunctioning or a sudden system shut-down etc. Whatever be the reason behind, it is your important data that has been inaccessible and techniques like Linux data recovery can help you recover them back.
In order to resolve the above issue, try using the command-line utility 'fsck', which can check the file system for possible file system corruptions and repair the same. Sometimes, if the damage/corruption to the file system is severe, 'fsck' fails to repair and terminates without doing anything. As Linux duplicates the file descriptor table and stores at different locations of the hard drive, if you are an advance user, you can input the location or the size of alternate super-block to the 'fsck', which can eventually fetch the information from there.

In case, if you failed to resolve the issue with 'fsck', you are left with only choice to format the drive and make a fresh installation. After that, you can restore your data from a valid backup file. In case, backup of data is not available or you failed to restore data from the backup, you can still recover all your valuable data back by using any Linux data recovery utility.

Linux Errors and data recovery

 The Linux OS is compatible with vast range of tablet computers, mobiles, video game consoles, mainframes, super computers etc. Even, statistics says that as, server OS, Linux accounts more than 50% of the whole global installations. Also,over the years, Linux OS has gained fair amount of popularity among the common home users with the Fedora, Ubuntu and Open SUSE distributions. Moreover, with the advent of smart phones, notebooks etc, which are running on embedded Linux, the OS has been more closely used by many users. Though Linux has advanced technology and features, sometimes, some errors  lead to data loss or inaccessibility and you need to look for any Linux data recovery software to recover back your valuable data.

In day to day usage of a Linux system, there can be enormous possibility of data loss situations, and you may not always successful in trouble shooting the system to gain access of your data. Hence, if you don't have a valid backup available or failed to restore the data from the backup, Linux recovery is the answer to bring back your data.

Common errors in Linux:

• Grub Error 12 – Invalid device requested.

• Grub Error  17 – Can not mount selected partition

• Error – Mount wrong fs type, bad option, bad super block on /dev/hdb2.

• Error – Too many mounted file systems.

• File system error.

There can be many such errors leading to the loss or inaccessibility of your Linux data. In such cases, if you are a technical person, then you can trouble shoot at the low-level. You can  run the 'fsck' command to detect and fix such error. Prior to running the 'fsck' command, first, you need to go to the single user mode. Then, you have to unmount the file system partition, you are going to work upon, if it is not the root file system. If you don't take enough care to unmount the file system, the 'fsck warns you, such as- 'The file system is mounted, do you want to continue anyway?' Saying yes to the message, may result in the loss of your data, because, at times, 'fsck' writes directly to the disk.

If you need to check the root file system based partition, you have to boot the system in single user mode and run the 'fsck' with a '-b' option so that it will run in a read-only mode. Also, the '-b' option directly go to the 'init' and makes an emergency booting while skipping the other start-up scripts.

Sometimes, 'fsck' fails to run or exits without running at all. At that time, you need to force run the utility with '-f' option. This is a case of severe corruption and you need to give additional information to 'fsck', such as the size of the alternate superblock or the address of the superblock to fetch the data and fix the error.

However, sometimes, these low-level recovery process is tedious as well as risky with respect to your valuable data. Hence, you can go for any Linux data recovery software, which can recover the data for you safely.

stellar Linux Partition recovery software

Linux is basically a command based OS where, in this operating system there is a command for each function and users, who use Linux based systems are usually known as more technically sound person. But, however tech savvy one may be, there are thinks that are beyond any one control like the case of  accidental deletion of data it is quiet common even in case of Linux machine. Moreover, sometimes while resizing partitions with various third-party tools, important existing Linux partition gets accidentally deleted causing a serious situation of data loss . In such a case of Linux partition deletion, the thing that is most required is the data recovery software for Linux to recover your lost partition .

Users quiet often makes multiple logical partitions to a single hard disk drive for the convenience of data storage. Moreover, Linux OS based computers are often with multiple partitions and each of the individual partition has a fixed size. It is quite common that the need of partition space changes and hence, the need to resize the partition arises. Though, there are several partition resizing tools for Linux systems available on line, there lies a number of potential risks of partition loss as well. Therefore, the whole process of partition resizing becomes more complex than it actually seems.

There can be a number of causes behind the loss or deletion of a partition, while partition resizing. Moreover, the user must gain enough knowledge before dealing with the partitions as they contain your valuable data. However, once, your Linux partition gets deleted, you can be able to restore it from your previous valid backup. In case, you do not have any good backup or due to any unresolved reason, failed to restore data from the backup, then, you have to take the help of an efficient Linux data recovery software to recover your lost partition back.

Linux partition recovery software are designed to recover all your lost, deleted, formatted or inaccessible Linux based partitions or volumes with ease. These utilities are powerful enough to scan the drive, locate your lost partitions and recover all the data from them. Moreover, with detailed instructions based graphical user interface, these utilities are simple in usage even for the users, who are not so proficient in terms of computer technology.

Linux Volumes are inaccessible due to I/O error what to do now?

This is possible in Linux OS to install and run the system software on a single hard disk partition. Such type of configurations are easy to establish . But if you divide your Linux hard disk into multiple volumes/ Partitions, you can effectively manage your critical data and get several other benefits. But in some situations, you might encounter I/O errors while accessing logical hard drive volumes and they become inaccessible. This behavior of Linux system results into critical data loss situations and require Linux drive Recovery to be sorted out.

While this is true that Linux OS would work fine on the hard drive with only one large partition, but there are several benefits of dividing the hard drive into at least four volumes (home, root, swap and usr). The major benefits of partitioning the hard drive are as given below:

First, it helps you to reduce the time required for carry out file system checks (while booting the system and carrying out manual checkup), because these checks can be performed simultaneously. With several volumes, it is quite easy to perform checkup.

Second, with many volumes, you can mount one or more of the volumes in read only mode. For example, when you consider that everything in the /home directory would not be touched even by the root, you can mount home in read only mode.

Finally, the most important advantage that hard drive volumes provide is absolute data protection. If anything goes wrong with your OS and you've to format the primary volume and then reinstall the OS. All of the data stored in secondary volumes would remain safe.

Although, this is quite useful to create several hard drive volumes, but in some situations the volumes might become inaccessible and you may encounter error messages while opening them. As an example, while accessing Linux hard drive volume, you may come across below error which put you in need of Linux Recovery:

“[ 234.284559] Buffer I/O error on device f 60. Logical block 0
[ 272.376782] Buffer I/O error on device f 60. Logical block 0”

In all these cases, Linux Data Recovery Software helps you to recover lost data. These software perform Recovery of Linux  system by thoroughly scanning affected hard drive using advanced scanning mechanisms.
