Since version 2.0, Proxmox VE offers a [[high availability]] option for clusters based on the [[Corosync Cluster Engine|Corosync]] communication stack. Starting from the PVE v.6.0, Corosync v.3.x is in use (not compatible with the earlier PVE versions). Individual virtual servers can be configured for high availability, using the built-inintegrated HA ha-manager.<ref>{{cite web|url=https://git.proxmox.com/?p=pve-ha-manager.git;a=summary|title=PVE HA Manager Source repository|access-date=2020-10-19}}</ref><ref>{{cite web|url=https://pve.proxmox.com/pve-docs/chapter-ha-manager.html#_how_it_works|title=Proxmox VE documentation: High Availability|access-date=2020-10-19}}</ref> If a Proxmox node becomes unavailable or fails, the virtual serversmachines can be automatically moved to another node and restarted.<ref>{{cite web |url=http://www.jaxlug.net/index.php/2014/07/16 |title=High Availability Virtualization using Proxmox VE and Ceph |publisher=Jacksonville Linux Users' Group |access-date=2017-12-15 |archive-date=2020-11-30 |archive-url=https://web.archive.org/web/20201130000142/https://www.jaxlug.net/index.php/2014/07/16 |url-status=dead }}</ref> The database and [[Filesystem in Userspace|FUSE]]-based Proxmox Cluster filesystemfile system (pmxcfs<ref>{{cite web |title=Proxmox Cluster File System (pmxcfs) |url=https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_pmxcfs |website=Proxmox VE Administration Guide |access-date=15 November 2022}}</ref>) makes it possible to perform the configuration of each cluster node via the Corosync communication stack with [[SQLite]] engine.<ref name="drilling" />
Another HA-related element in PVE is the distributed filesystemfile system [[Ceph (software)|Ceph]], which can be used as a shared storage for guest machines.<ref>{{cite web |last1=Ladyzhenskyi |first1=Pavel |title=Setting up a Proxmox VE cluster with Ceph shared storage |url=https://medium.com/@qwonkiwow/setting-up-a-proxmox-ve-cluster-with-ceph-shared-storage-e7a4f652f321 |website=Medium.com |access-date=12 November 2023}}</ref>
