Global File System 2 - cluster tools

 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 the gfs_controld daemon and associated tools required
 to use GFS2 in a cluster. Virtually every user of GFS2 will need to install
 this package.
