pvecm

Pvecm is a command line tool used in Proxmox VE, a virtualization management platform. It stands for "Proxmox VE Cluster Manager" and is responsible for managing and configuring the cluster functionality in Proxmox. Pvecm allows you to create and manage a cluster of Proxmox VE nodes, enabling the creation of highly available and fault-tolerant virtual environments. With pvecm, you can add or remove nodes from the cluster, manage cluster-wide shared storage, and configure cluster communication settings. The tool uses various algorithms and techniques to ensure that the cluster operates efficiently and maintains high availability of virtual machines. Pvecm relies on a distributed consensus algorithm to achieve cluster synchronization and agreement among the nodes. It supports both two-node and multi-node clusters, making it scalable and flexible for various deployment scenarios. The command line tool provides extensive logging and debugging capabilities to assist in troubleshooting and monitoring the cluster's health and performance. Pvecm also integrates with other Proxmox VE features, such as live migration and backup, to enhance the overall reliability and efficiency of the virtual environment. Proxmox VE includes comprehensive documentation and community support to help users effectively utilize pvecm and build robust cluster configurations.
