Hello guys! i have a 3 node Elasticsarch with indexes with 1 primary and 1 replica shards, but for now i want to add path.repo parameter for backup on NFS according to docs, i should restart Elasticsearch one by one node and its ok! but what about data? for example if 1 restart 1 node, will the replicas shards on another nodes R/W? or not? it's safe to reboot a node in cluster containing 3 nodes and 1 primary and 1 replica shards thank you! ---
