== Introduction ==
This new storage plugin supports the use of GlusterFS volumes. It uses a fuse mount point for volume management (create/delete/snapshot,rollback,...) but  Qemu accesses the virtual disk images directly to get best performance.
This storage plugin is a technology preview, available since Proxmox VE 3.1.

Storage pool type: glusterfs

GlusterFS is a scalable network file system. The system uses a modular design, runs on commodity hardware, and can provide a highly available enterprise storage at low costs. Such system is capable of scaling to several petabytes, and can handle thousands of clients.

Note After a node/brick crash, GlusterFS does a full rsync to make sure data is consistent. This can take a very long time with large files, so this backend is not suitable to store large VM images.


The backend supports all common storage properties, and adds the following GlusterFS specific options:


GlusterFS volfile server IP or DNS name.


Backup volfile server IP or DNS name.


GlusterFS Volume.


GlusterFS transport: tcp, unix or rdma

Configuration Example (/etc/pve/storage.cfg)
glusterfs: Gluster
        volume glustervol
        content images,iso

File naming conventions

The directory layout and the file naming conventions are inherited from the dir backend.

Storage Features

The storage provides a file level interface, but no native snapshot/clone implementation.
