About this tag
The pmxcfs tag on WindowsForum.com covers discussion of the Proxmox Cluster File System and its role in Proxmox VE hosts, including how this cluster filesystem contributes to persistent background writes on boot SSDs. The tagged content examines claims about SSD wear from idle Proxmox nodes, noting that pmxcfs is one source of small writes alongside historical monitoring data, while measured idle-node writes were far less dramatic than some reports suggest. For Windows admins and homelab operators migrating workloads from Hyper-V or VMware, the practical takeaway is to treat the Proxmox boot disk as an actively used system volume rather than an idle one.
