The mount count and maximum mount count in the superblock of the ext2 file system serve a crucial role in maintaining the integrity and reliability of the file system by determining when file system checks should be performed.

The mount count is the number of times the file system has been mounted since the last check, while the maximum mount count is a predefined threshold for how many mounts are allowed before a check is prompted. When the mount count reaches the maximum mount count, the system will automatically trigger a check the next time the file system is mounted. This process is important because it helps identify potential issues or corruption within the file system before they lead to more significant problems, ensuring data integrity and preventing data loss.

By regularly checking the file system through this mechanism, ext2 can uphold a higher standard of data reliability and minimize the risk of file system failures. Hence, the concept relates directly to maintaining system health rather than directly managing file access, determining file size limits, or tracking disk usage statistics.
