Objective 2: Maintain the Integrity of Filesystems
Over the course of time, active filesystems can develop problems, such as:
A filesystem fills to capacity, causing programs or perhaps the entire system to fail.
A filesystem is corrupted, perhaps due to a power failure or system crash.
A filesystem runs out of inodes, meaning that new filesystem objects cannot be created.
Carefully monitoring and checking Linux filesystems on a regular basis can help prevent and correct these types of problems.
