Thanks for explanation. Just some real case for clearance. Imagine node A is crashed completely (disk failure). It means that I will not be able to start it. Do I understand correctly that I have to install jboss messaging server on new machine and assign the same serverpeer id as it was on node A to be able process remaining message?
