DESCRIPTION

20       This  tool  is  part  of  glusterfs(8) package, which is used to
21       mount using GlusterFS native binary.
22
23       mount.glusterfs is meant to be used by the mount(8) command  for
24       mounting  native GlusterFS client. This subcommand, however, can
25       also be used as a standalone command with limited functionality.
