A couple of general remarks:

* You should not cluster AD servers with ctdb, but file servers,
  typically domain member servers.

  For s4 that means to start only the source3-components,
  typically smbd and winbindd.

* You will not only need DRBD but a proper clustered file system,
  the storage of which might be replicated with DRBD.
  Examples are GFS2 , OCFS2, GPFS, and (I guess) Ceph.

  If you replicate a simple local file system (like ext or xfs),
  and access it simultaneously from multiple nodes, you risk data
  corruption.

Could you please attach your bin/config.log or upload it
somewhere for further analysis?
