NAME

       GlusterFS - clustered file system

SYNOPSIS

       glusterfs [options] [mountpoint]

DESCRIPTION

       GlusterFS  is a clustered file system, capable of scaling to several peta-bytes.  It aggregates various storage bricks over Infiniband RDMA
       or TCP/IP and interconnect into one large parallel network file system. Storage bricks can be made  of  any  commodity  hardware,  such	as
       x86-64 server with SATA-II RAID and Infiniband HBA.

       GlusterFS  is  fully POSIX compliant file system. On client side, it has dependency on FUSE package, on server side, it works seemlessly on
       different operating systems. Currently supported on GNU/Linux and Solaris.

   Basic options
       -f, --volfile=VOLUME-FILE

       --read-only
