Subject Re: Quorum: killing 1 out of 3 server kills the cluster (?)
Date Thu, 09 Dec 2010 15:44:17 GMT

The UnavailableExceptions  will be thrown because quorum of size 2
needs at least 2 nodes to be alive (as for qurom of size 3 as well).

The data won't be automatically redistributed to other nodes.

But when I shut down one of them UnavailableExceptions are thrown. Why is that? Isn't that
the sense of quorum and a fault-tolerant DB that it continues with the remaining 2 nodes and
redistributes the data to the broken one as soons as its up again?
