pve-moosefs

MooseFS integration for Proxmox VE

This plugin enables native support for MooseFS as a storage backend in Proxmox VE.

⚠️ Disclaimer

This project is highly experimental.

⚠️ Do NOT use snapshots in MooseFS block device (bdev) mode. They are currently unsafe and may result in data loss. Snapshot support is still under active development and will remain experimental until this warning is removed.
