What if your have noted while monitoring disk space, that you starting to run-out of space on your '''home''' file-system, although you '''do NOT have any available space on your current hard disk. ?''' You could obtain an additional hard-drive.We can '''add a new <u>virtual</u> hard-drive''' (which will serve as a physical volume to the volume group), and extend the '''home''' logical volume to make use of the new available space. Creating virtual hard drives is not only inexpensive, but a great way for students to learn now to simulate growing the size of the file system.!
