Summary

Efficiently managing the storage of your servers will ensure that things continue to run smoothly, as a full filesystem can definitely cause your server to grind to a halt. Thankfully, Linux servers feature a very expansive toolset for managing your storage, some of which are a source of envy for other platforms. As Linux server administrators, we benefit from technologies such as LVM, and utilities such as ncdu, as well as many others. In this chapter, we explored these tools and how to manage our storage. We covered how to format, partition, mount, and unmount volumes, as well as managing the fstab file, LVM, monitoring disk usage, and more.

In the next episode of our Ubuntu Server saga, we'll work through connecting to networks. We'll configure our server's hostname, work through examples of connecting to other servers via OpenSSH, and take a look at IP addressing.
