gfs-tools 3.0.2-2ubuntu1 (amd64 binary) in ubuntu karmic

 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 available services without the single point
 of failure a file server would be.
 .
 This package contains userspace tools for creating and managing global
 file systems. GFS itself is a set of kernel modules.
 .
 Note: the package requires gfs2-tools installed and it's known to work fine
 even if GFS2 is highly experimental and *MUST NOT* be used in production
 environment yet.
