pvecm manages Proxmox VE cluster membership. It handles creating clusters, joining nodes to existing clusters, and removing nodes. The cluster provides high availability, live migration, and shared storage capabilities.
Proxmox clustering uses corosync for cluster communication and pmxcfs for distributed configuration storage. All cluster nodes share the same configuration.

Creating a cluster is irreversible without reinstalling. Removing nodes requires the node to be offline and clean shutdown procedures. Network configuration must allow cluster communication (default port 5405-5412).

Part of Proxmox VE, enabling multi-node deployments with shared management. Built on corosync cluster engine and provides foundation for high-availability features.
