Use the ‘df -I’ command to check the inode usage on your file systems. This will show you the percentage of inode utilization for each mounted file system.
Uninstall unnecessary software or libraries that you no longer need. This can free up both disk space and inodes.
Identify and delete unnecessary or temporary files. You can use commands like ‘find’ to locate files based on criteria like size or last modification time.
Check and clean up log files, especially those in ‘/var/log/’. Logs can accumulate and consume a significant number of inodes.
Sometimes, files can be deleted but still hold open by a process. These are called "orphaned inodes." You can use the ‘lsof’ command to identify and stop processes holding onto deleted files.
