Let's say What if your have noted while monitoring disk space, that you have starting to run -out of disk space on your '''centos2''' VM, and you need more space on the '''/home''' file-system in order to host more web-pages, or to support a larger databasealthough you do NOT have any available space on your current hard disk. What are your options? Getting a replacement You could obtain an additional hard-drive would probably require re-installation of the operating system and/or backing up and restoring data on the old hard disk. Because we're using LVM we can avoid this problem. We can '''add a new <u>virtual</u> hard-drive''' (which will serve as a physical volume) to the volume group), and extend the root '''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.
