Overview of this book

Proxmox is an open source server virtualization solution that has enterprise-class features for managing virtual machines, for storage, and to virtualize both Linux and Windows application workloads. You'll begin with a refresher on the advanced installation features and the Proxmox GUI to familiarize yourself with the Proxmox VE hypervisor. Then, you'll move on to explore Proxmox under the hood, focusing on storage systems, such as Ceph, used with Proxmox. Moving on, you'll learn to manage KVM virtual machines, deploy Linux containers fast, and see how networking is handled in Proxmox. You'll also learn how to protect a cluster or a VM with a firewall and explore the new high availability features introduced in Proxmox VE 5.0. Next, you'll dive deeper into the backup/restore strategy and see how to properly update and upgrade a Proxmox node. Later, you'll learn how to monitor a Proxmox cluster and all of its components using Zabbix. Finally, you'll discover how to recover Promox from disaster strikes through some real-world examples. By the end of the book, you'll be an expert at making Proxmox work in production environments with minimal downtime.

The Proxmox cluster file system

Proxmox is a cluster-based hypervisor. It is meant to be used with several server nodes. By using multiple nodes in a cluster, we provide redundancy or high availability to the platform while increasing uptime. A production virtual environment may have several dozens to several hundreds of nodes in a cluster. As an administrator, it may not be a realistic scenario to change configuration files in the cluster one node at a time. Depending on the number of nodes in a cluster, it may take several hours just to change one small argument in a configuration file of all the nodes. To save precious time, Proxmox implemented the clustered filesystem to keep all the configuration files or any other common files shared by all the nodes in the cluster, in a synchronous state. Its official name is Proxmox Cluster file system (pmxcfs). The pmxcfs is a database...
