Explanation:
File SystemThe following list shows the process of mapping user files to the disk storage that uses an
LVM:
1. Files are created and managed by users and applications.
2. These files reside in the file systems.
3. The file systems are mapped to file system blocks.
4. The file system blocks are mapped to logical extents of a logical volume.
5. These logical extents in turn are mapped to the disk physical extents either by the operating
system or by the LVM.
6. These physical extents are mapped to the disk sectors in a storage subsystem.
If there is no LVM, then there are no logical extents. Without LVM, file system blocks are directly
mapped to disk sectors.
