Paxos algorithm allows to keep state of distributed processes
consistent.  An accessible paper about it is:
http://research.microsoft.com/en-us/um/people/lamport/pubs/paxos-simple.pdf
 It seems there were several attempts at implementing generic Paxos
library in Erlang (https://www.google.com/search?q=paxos+erlang), I
don't know how matured these implementations are,  maybe they can
serve you as a starting point.

Cheers,
