システムが故障した後、ディスクがいっぱいになったため、赤色のインデックスがいくつかあります。 しかし、私は失われたシャードを再割り当てすることはできません。それは私が基本的にrerouteコマンド（ドキュメントhere）のすべてのオプションを試してみましたelasticsearch - 利用可能なシャードのコピーはありませんか？

「利用可能シャードのないコピーが存在しない」と言います。しかし、それはこのように私に400エラー..を与える：
curl -XPOST 'localhost:9200/_cluster/reroute?pretty' -H 'Content-Type: application/json' -d'
{
"commands" : [
{
"allocate_replica" : {
"index" : "myindex", "shard" : 0,
"node" : "node2"
}
}
]
}'
応答：
{
"error" : {
"root_cause" : [
{
"type" : "illegal_argument_exception",
"reason" : "[allocate_replica] trying to allocate a replica shard [myindex][0], while corresponding primary shard is still unassigned"
}
],
"type" : "illegal_argument_exception",
"reason" : "[allocate_replica] trying to allocate a replica shard [myindex][0], while corresponding primary shard is still unassigned"
},
"status" : 400
