Mnesia Clustering

If I am clustering 2 nodes together, from my experimenting and reading up online I understand that Node A will be like a "master" node and Node B will copy the tables over if I want them to. (Otherwise it will just access them remotely.)

What happens though if Node B goes down? Does it just recopy the data that's been changed since it was last up?

Also what happens if Node A goes down. Is Node B still usable? If so, if data is changed on Node B, does Node A copy it over to itself? My understanding so far is that Node A doesn't care about what Node B says, but someone please tell me I'm wrong.
