Hello, I try to set up a clustered samba server (on Novell SLES11SP2) based upon CTDB and NFS. My problem is that I do not yet understand the structure of the setup when using NFS. I followed the documentation in http://wiki.samba.org/index.php/CTDB_Setup#Setting_up_CTDB_for_clustered_NFS As far as I understand this documentation, it should be possible to set up a samba cluster say having 3 nodes where I can use NFS instead of a cluster filesystem like OCFS for the shared data directory that ctdb needs. My initial thought was that I have exactly one NFS share (provided by one NFS...
