   9 Storage pool type: `glusterfs`
  10
  11 GlusterFS is a scalable network file system. The system uses a modular
  12 design, runs on commodity hardware, and can provide a highly available
  13 enterprise storage at low costs. Such system is capable of scaling to
  14 several petabytes, and can handle thousands of clients.
  15
  16 NOTE: After a node/brick crash, GlusterFS does a full `rsync` to make
  17 sure data is consistent. This can take a very long time with large
  18 files, so this backend is not suitable to store large VM images.
