What to do when data loss occurs in Linux due to corrupt File Descriptors
In a Linux operating system based computer, directories, blocks, sockets, files, and other items are referred by their corresponding file descriptors. File descriptor is one of the significant data structures of Linux operating system. It is very essential for the file descriptor to be consistent for proper working of your system. In case it is damaged, you can not access your precious data from the disk and face severe data loss situations. In such cases, you need to opt for Linux data recovery solutions.
If you encounter any error from your system related to file descriptor corruption, it can be due to corruption to the Linux file system. File system corruption is a major reason of data loss and cause serious problems for you. For a practical instance of this problem with your Linux system, you may encounter the following error message when you attempt to access data from your Linux hard drive-
“Bad file descriptor”
The above error may also occur while booting your system or mounting a hard drive volume. It renders your precious data inaccessible. At this point, you need to find out the root of this problem and fix it using Linux recovery solutions.
Grounds of the problem-
You may encounter this behavior of Linux operating system due to any of the following reasons-
Linux uses /dev/null file that removes all data, which is written to the file after reporting that write process is completed successfully. You might encounter the file description problems if the file is deleted.
If this error occurs while accessing any file from the hard drive, it can be due to corrupt disk blocks or file system corruption.
Resolution
Try using the below methods to sort out this issue-
To fix overwritten or deleted /dev/null file problems, you are required to replace the file with suitable iNode.
Run fsck command on the affected Linux hard drive to resolve file system inconsistency and hard drive integrity issues. Before you run this command, file system must be un-mounted and system must be running in single-user mode.
Restore data from the most recent backup. It is an efficient Ext3 recovery solution to get your precious data back. If none of the above methods work, use third-party Linux recovery software to perform data recovery Linux. The applications are capable of retrieving your significant data in all data loss situations.
