[Gluster-users] Need help making a decision choosing MS DFS or Gluster+SAMBA+CTDB
An example of a working share on samba4: You can choose to work with vfs objects= glusterfs Glusterfs:volume=yourvolume Glusterfs:volfile.server=Your.server Form e it turned out to be too buggy.

Thanks everyone. So from reading all your comments, I understand that if I need an active / active synchronized setup for higher workloads, Gluster is for me. Other then that, DFS-R is a good option for data replication at the expanse of latency of the replicated data to the secondary node, and only one server is active per CIFS share. Does DFS-R works well on high rate of changes? Found from other users use cases that DFS-R caused server hangs and such, hope it was fixed in Win2K12 server.
