Thanks Michael,
shutdown all of them is not a choose for me, in a HA cluster, how to
re-seed the cluster data in online mode? take above neo4j instances as an
example:
1. Delete all data in neo4j_1 ( the master instance )
2. reload data into neo4j_1
then how the synchronization works?
1. When delete all the data in master instance
1) all the data stored in slaves will be deleted too?
2) delete the master data willl not impact the slaves?
2. the reloaded data in master server will sync to slaves by default.
Thanks in advance.
