In this chapter, we took a look at the storage options that are supported by Proxmox and their advantages and disadvantages. We also saw the types of virtual image files that can be used with Proxmox and when to use them. We learned how to configure different storage options using NFS, ZFS, RBD, and Gluster as storage backends. Storage is an important component for Proxmox clustering because this is where virtual machines are created and they operate from. A properly implemented storage system is very critical to make any cluster a successful one. With proper planning of different storage requirements and choosing the right format and option, a lot of hassle and frustration can be minimized later on.
In the next chapter, we will see how to create and manage KVM-based virtual machines. We will also examine virtual machine configuration files and learn some advanced configuration options.
