To cleanly shut down or hot swap storage hardware on a UNIX or UNIX-like system, you must be able to unmount any file system that uses storage on that device. However, you can't unmount a file system if files or directories in that file system are in use. The lsof and fuser commands can help you identify and terminate the processes that are using files on or executing from the storage devices that your system is using. Using these commands simplifies the traditional detective work associated with finding the processes that are preventing you from unmounting storage devices, decreasing frustration, and helping you proceed with critical system administration tasks.
