          A cluster filesystem.

          Allows a cluster of computers to simultaneously use a block device
          that is shared between them (with FC, iSCSI, NBD, etc...).  GFS reads
          and writes to the block device like a local filesystem, but also uses
          a lock module to allow the computers coordinate their I/O so
          filesystem consistency is maintained.  One of the nifty features of
          GFS is perfect consistency -- changes made to the filesystem on one
          machine show up immediately on all other machines in the cluster.
