Node failure is that the machine is not able to connect to storage network and serve data.

Mirror type volume will keep serving full data from another server.  For example, a  mirror type volume involves six servers means three mirrored pairs and data is distributed across these pairs.  If a server is down, data is served by its mirror server.  If pair of server is down, data stored in those pair won't be available, but we get other data.

Upcoming 3.1 version will have dynamic volume, in which we can specify a replacement node.  In 3.0, there is no such option.
