A Linux based computer system becomes unbootable in case its file system gets corrupted or damaged. In most of these situations, a Linux user encounters an error message that does not allow him/her to access the data saved on the Linux hard drive. Few main causes for corruption in file system (either EXT4, EXT3, or EXT2) can be improper system shutdown, inode corruption, superblock damage, virus infection, accidental system shutdown, and operating system malfunction.
To overcome such situations, the user needs to repair the damaged file system using ‘e2fsck’ command. This command checks and repairs the corrupted files system in almost all cases. However, the command does not ensure 100% repair in all file system corruption scenarios. For cases where the above command fails, the user needs to reinstall Linux operating system and then restore data from an updated backup. But, in the absence of a valid backup, you will need to opt for a commercial Linux Recovery application.
To illustrate the above situation, consider a practical scenario where you encounter the below error message while trying to boot your Linux system:
“ext2fs partition type 0x83….. ext3-fs: journal inode is deleted….mount: error 22 mounting ext3 error 2 mounting name switchroot: mountfailed:22 umount/initrd/dev failed:2 kernal panic – not syncing.”
Once the above error message flashes on your screen, the system becomes unbootable, further resulting in inaccessibility of hard drive data.
The above error message appears when the files gets corrupted or damaged.
Follow the below guidelines to resolve the above error message:
1. Run ‘e2fsck’ command to repair the corrupted file system.
2. In case, the above command fails to repair the file system, follow the below steps:
Reinstall the Linux operating system.
Restore the data from an updated backup.
For cases where there is no backup available, use a third-party Linux Data Recovery software.
A Linux Data Recovery utility is a powerful tool that is specifically designed to recover data post clean reinstall of Linux operating systems. Such tools are very easily understandable and do not require any technical knowledge.
Stellar Phoenix Linux Data Recovery is a safe, fast, and effective Linux Recovery utility that recovers data from formatted Ext4, Ext3, Ext2, FAT file system based volumes. Supported by almost all Linux distributions, the utility recovers every file and folder, irrespective of its type and size. This powerful repair tool includes functionalities like hard drive cloning, create image, and S.M.A.R.T.
