Hi All, Mistakenly we shut downed 3 nodes in the cluster in the same time. They contained both the primary shard and its replica ☹ ES probably decided that it has lost the entire shard and created new shard but with zero documents. We've returned those 3 previously shut downed nodes to the cluster but the new shards still empty . So looks like we lost the shard's data. Fortunately we have a backup of ES data folder from the lost shard The question is : how can we recreate the data? Will simple copy to the empty shard resolve it? What would you recommend?
