question is I can manage to get the correct replica state if I start and stop solr using command line. how if solr failure or crashed, how can I get the correct replica state?
As I have stated elsewhere on this mailing list, actual Solr crashes are extremely rare. The most common reason for Solr to die suddenly is the intentional death that happens when OutOfMemoryError is thrown. Other causes are possible, but normally indicate serious problems with the system itself.
If Solr is ungracefully killed due to OOME or some other reason, then as Erick mentioned, live_nodes and the clusterstate will not be updated immediately. Eventually, when attempts to use those replicas fail, the remaining Solr servers will notice that the node is down and update the clusterstate. But it won't happen as soon as the node dies.
