Changes to GFS 6.1 for RHEL4 U3

      
   Red Hat GFS 6.1 contains no new features for Red Hat Enterprise
   Linux 4 Update 3.

   
   
Important Notes
   
   Multipath GNBD is not available with this and previous releases of  
   Red Hat GFS 6.1. That is, device mapper multipath (dm-multipath) 
   cannot use GNBD. GNBD without multipath *is* available.
   
   This release prevents the activation of snapshots in a clustered volume
   group.
