- [Instructor] In this lesson, we'll take a look at how to verify the integrity and availability of important resources and processes. As time goes by, a server will usually use more and more resources. Storage space is a good example. As the database grows, as users store more and more files, more and more gigabytes of storage space are used. In the cloud, it's relatively easy to add more disks or SSDs to a server. But how do we know when we're running out of storage space? Well, we can use the df, disk-free utility, but this output is a bit hard to read. For example, we can see how much space is used on a disk, but we see this in one kilobyte blocks. We can tell df to make this output a bit more human readable. With the -h option. Now, sizes are displayed in megabytes, gigabytes, and terabytes instead, where we see the letters M, G, or T. We can ignore the file systems that contain the word tmpfs. Those are virtual file systems that only exist in the computer's memory, not on…
