   1 GlusterFS Backend
   2 -----------------
   3 include::attributes.txt[]

   5 Storage pool type: `glusterfs`
   6
   7 GlusterFS is a salable network file system. The system uses a modular
   8 design, runs on commodity hardware, and can provide a highly available
   9 enterprise storage at low costs. Such system is capable of scaling to
  10 several petabytes, and can handle thousands of clients.
  11
  12 NOTE: After a node/brick crash, GlusterFS does a full 'rsync' to make
  13 sure data is consistent. This can take a very long time with large
  14 files, so this backend is not suitable to store large VM images.
