🕒 03:00–03:35
🏷️ Labels: Filesystem, Troubleshooting, Linux, Data Recovery
📂 Project: Dev
⭐ Priority: MEDIUM
Session Goal:
The session aimed to troubleshoot and resolve various filesystem issues on a Linux system, focusing on external drive recognition, file access, and filesystem corruption.
Key Activities:
- Troubleshooting External Drive Recognition: Steps were outlined to troubleshoot an external drive recognized as
/dev/sdbwith a partition/dev/sdb1. This included confirming the filesystem type, using filesystem-specific tools, manual mounting, and reviewing system logs. - Viewing File and Directory Permissions: Utilized the
ls -lcommand to view file and directory permissions, detailing the output structure and options for hidden files. - File Access Issues: Addressed potential causes and solutions for accessing file metadata, focusing on corrupted filesystems, symbolic links, hardware problems, and network drive issues.
- Removing Problematic Files: Provided a step-by-step guide for safely removing problematic files using command-line instructions.
- Resolving Input/Output Errors: Outlined troubleshooting steps for ‘Input/output error’ issues, including deleting files using inode numbers and performing filesystem checks.
- Filesystem Corruption Troubleshooting: A systematic approach was taken to address filesystem corruption and hardware issues, including backing up data and assessing hardware health.
Achievements:
- Successfully identified and applied solutions to various filesystem issues.
- Improved understanding of file permissions and filesystem troubleshooting techniques.
Pending Tasks:
- Further monitoring of the filesystem health and stability is recommended to ensure long-term resolution.
- Consider reformatting if issues persist despite troubleshooting efforts.
