If you mean that one node looses data from it's disk (e.g. the disk
melts).
In this case, on node restart, it will copy all the data from the
surviving node in the node group. i.e. you loose nothing.
Remember we have synchronous replication between nodes so that COMMIT
means that the data is on more than one node.
