Hello to everyone, Cluster health turned red when a node fell from the cluster. When I re-add the node, some directories automatically turned from red to green, but there is an index still red and I don't know what to do. It looks like it is trying to assign the primary and replica shard of the directory to the same node. There was no change when I set the replication number to 0. How do I assign a primary shard? I did some research and finally got this printout, but I have no idea what to do. ``` GET /_cat/shard?h=index,shard,prirep,state,unassigned.reason ticket 2 p INITIALIZING NODE_LEFT ticket 2 r

What is the output from the `_cat/recovery?v` endpoint? ---

Thank you for your answer. I could not find a solution. Finally I delete the index and re-created it. There is no problem right now. ---
