Linux data recovery after file descriptor corruption

When you open your Linux system, during the boot process, you can receive errors related to file system corruption and the system may get hang. You may face the following error messages:

"Activating swap partitions: dup2: Bad file descriptor [FAILED]

Setting hostname Leshkow2: dup2: Bad file descriptor [FAILED]

/etc/rc.sysinit: /dev/null: Read-only file system

/etc/rc.sysinit: /dev/null: Read-only file system

Mounting USB file system: dup2: Bad file descriptor [FAILED]

Initializing USB controller (usb-ohci): dup2: Bad file descriptor [FAILED]"

And

"Grep: /proc/mounts: No such file or directory

Checking root file system

dup2: Bad file descriptor [FAILED]"

when these error messages occurs, you get the Linux shell prompt. At this situation, your system becomes totally unusable

These situation occurs due to corrupted or missing file descriptors. Due to the same, Linux can not locate and access the boot files and thus displays the above error messages.

The file descriptors are conceptual keys to view files. Usually the file descriptors are the indexes for entries in Linux kernel-resident data structure, which contains details of all the stored files. The file descriptors are stored in file descriptor table.

When the file descriptors not working properly, OS can not locate the stored files and thus the accessibility of these files become impossible. To overcome this condition, you have to perform Linux data recovery.

Data Recovery Linux is the solution to retrieve your inaccessible, missing or lost data. It is potential using third party applications, known as Linux Recovery software.

Such recovery software are easy-to-use tools, which perform methodical scan of affected hard drive and recover all data from it. These software incorporate powerful scanning algorithms to scan the hard drive and salvage all lost data.

The Linux recovery tools come equipped with different set of functions. To ensure optimum data recovery in Linux, it is essential to implement quality and powerful recovery software. These software are designed with features like largely automated functionality, to-the-point documentation, self-descriptive graphical screens and user friendly recovery options to achieve full-fledged recovery in all logical data loss cases.
