If files and directories other than confluence.cfg.xml, which is the core file of local-home, are different from other nodes (or if they are previous files), booting seems to be possible, but it is certain to request an index snapshot that exists in shared-home and take it. Shouldn't we disable the node while it's coming?
This seems to be an important part to apply to replicaCount of kubernetes deployment and Cloud (example AWS) Autoscaling service.
