Description

Session Goal: The session aimed to troubleshoot and resolve various filesystem-related issues on a Linux system, particularly focusing on an external drive and general filesystem errors.

Key Activities:

• Troubleshooting an external drive /dev/sdb and its partition /dev/sdb1, including confirming the filesystem type and using specific tools for manual mounting and system log review.
• Viewing file and directory permissions using the ls -l command to understand access rights and identify potential permission issues.
• Addressing file access issues by diagnosing potential causes such as corrupted filesystems, symbolic links, hardware problems, and network drive issues.
• Safely removing problematic files using command-line instructions, including navigation, verification, and deletion.
• Resolving ‘Input/output error’ issues by deleting files using inode numbers, performing filesystem checks, and checking for hardware issues.
• Systematically troubleshooting filesystem corruption, including backing up data, checking the filesystem, assessing hardware health, and considering reformatting.

Achievements:

• Successfully identified and addressed various filesystem issues, improving system stability and data accessibility.

Pending Tasks:

• Monitor the external drive for recurring issues and perform regular filesystem checks to ensure ongoing stability.
