Hi Having tried hard with DFS (and finding it very trying), we had to give up and to go with HA. We built an entry level cluster. There is a lot of badly explained/wrong/misleading information about this. We've tried to explain it in plain English here: http://linuxcostablanca.blogspot.com.es/2014/07/samba4-cluster-for-ad-drbd-ocfs2-ctdb.html HTH to at least save you some valuable time. Cheers, Steve
