The RECMASTER and LMASTER capabilities can be disabled when CTDB
is used to create a cluster spanning across WAN links. In this
case CTDB acts as a WAN accelerator.

DMASTER for records, so can still have Samba running on them. However,
to find the who is DMASTER the "remote" nodes will still need to go to
the LMASTER. I've never understood the term "accelerator" in this
