Hello,

I have the following issue:

{"error":{"root\_cause":[{"type":"unavailable\_shards\_exception","reason":"[archival\_collection][2] primary shard is not active Timeout: [1m], request: [delete {[archival\_collection][object][ARC1]}]"}],"type":"unavailable\_shards\_exception","reason":"[archival\_collection][2] primary shard is not active Timeout: [1m], request: [delete {[archival\_collection][object][ARC1]}]"},"status":503}

When we ran the explain command as below then we received below issue:

Command: curl -X GET "localhost:9200/\_cluster/allocation/explain?pretty"

**issue**  
"unassigned\_info" : {  
"reason" : "REPLICA\_ADDED",

},

"explanation" : "the shard cannot be allocated on the same node id [oHuLmxrGTCKl88XllP-nqQ] on which it already exists"  
}  
]  
}  
}

Can you please check this and let me know how we can fix this issue?

Thanks!
