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 operate from. A properly implemented storage system is crucial to making any cluster a successful one. With proper planning of different storage requirements and by 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 install and configure a Ceph storage system and integrate it with a Proxmox cluster.
