This package is part of the red hat cluster suite, a complete high-availability solution.

the global file system allows a cluster of machines to concurrently access shared storage hardware like sans or iscsi and network block devices. gfs can be deployed to build high-availability services without the single point of failure of a file server.

this package contains tools for creating and managing global file systems. gfs itself is a set of kernel modules.

note: the package requires gfs2-tools installed; this is known to be reliable even though the gfs2 kernel modules themselves are highly experimental and *must not* be used in a production environment yet.
