In this chapter, we looked at the location of the important configuration files needed to run a Proxmox cluster. We also looked at the configuration files from inside to have a better understanding of the parameters used and other possible values for different parameters. As mentioned earlier, most of these configuration files can be changed via the Proxmox GUI. But when the GUI becomes inaccessible for any reason, knowing where these files are located can save a tremendous amount of time by accessing them through the CLI.

In the next chapter, we will take a look at the various storage systems that can be used with Proxmox and the different types of disk images and their use cases.
