Hello again,

the point 1) is clear, but I have some doubts about the point 2).

Let me divide the data stored in a cache in primary and backup. When a node 
die, to avoid network storm, the primary data is not automatically gravitated. 
If so, why the automatic gravitation is done for the backup ?
In fact in the example that I posted, the primary data contained in the node C 
or cache 2 (the node three) is automatically copied in the backup data of the 
node B (or cache 1).

And then, when a node die, the cluster is not 'homogeneous' anymore. Some data 
has a backup and some other don't. In this situation, without a specific 
application code that force the gravitation, another fault can cause 
information loss.

thanks and regards
gianluca
