In Linux and UNIX operating systems, daemon is the computer program that runs in the background other than direct control of a user. You can use these daemons to configure your hardware (like devfsd) and perform tasks like scheduled run of cron in your Linux system. But sometimes, these programs fail to start while booting the Linux system. It can occur due to certain inconsistencies or corruption issues in the file system. In such situations, you need to use a recent and valid data backup to restore the data. However, if the data backup fails to provide the required results, efficient Linux Data Recovery applications can be used to recover the lost files. Consider a scenario, you try to boot Linux system and daemons fail to start. Additionally, when you reboot the system, you get a GRUB error message. When you use the boot disk to mount your root partition, it fails. CauseAs described above, if root partitions file system suffers corruption, the daemons may fail to start at bootup. It can occur if any of the metadata structures like superblock, inode etc. is damaged due to user errors like unexpected system shutdown, incorrect use of commands and more. Solution You can follow these steps to solve this issue: You can run the fsck command to diagnose and repair file system issues of hard disks root partition. The fsck is a command-line utility that can fix various issues of file system corruption. If you find errors that fsck cant fix and still observe the same issues, you need to reformat the hard disk and restore the lost data from a recent data backup. A format operation erases all the data from the selected Linux partition or volume. But, if you do not have a valid data backup, you need to scan your hard disk using Linux Recovery software to recover the lost or inaccessible files. Linux Data Recovery applications are specially designed to scan drives affected from logical data loss. These software can locate the missing information and t hen safely restore it. You will find such Data Recovery Linux tools with user-friendly interface plus remarkably fine recovery capabilities. Stellar Phoenix Linux Data Recovery is an effective Linux Recovery solution. The application supports Ext2, Ext3 and ReiserFS file systems. It is compatible with most of the Linux distributions like RedHat, TurboLinux, Slackware etc. It gets installed on Windows (Windows Vista, XP, 2003 and 2000) and the affected Linux hard drive should be connected as slave.
