Vincent Pelletier authored Jul 31, 2009

When the disconnection is not caused by a broken node event, pick the state from a mapping: by default, a disconnected node is considered down (ie, removed from node manager as soon as it gets disconnected), with the exception of a storage node (it must be kept in partition table, so it must also be kept in node manager).
