.SH NAME
GlusterFS \- Clustered Filesystem.
.SH SYNOPSYS
.B glusterfs 
.I [options] [mountpoint]
.PP
.SH 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 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 FileSystem. On client side, it has dependency on FUSE package, on server side, it works seemlessly on different OSes. (Currently supported on GNU/Linux, Mac OSX, FreeBSD, OpenSolaris).
