Question

在磁盘已满导致系统出现故障后，我有一些红色索引。但我无法重新分配丢失的碎片。它说“没有可用的碎片副本”

        }
      ]
    }
  }
}

我基本上尝试了reroute命令的每个选项（文档here）。但它给了我400个错误..像这样：

curl -XPOST 'localhost:9200/_cluster/reroute?pretty' -H 'Content-Type: application/json' -d'
{
    "commands" : [

        {
          "allocate_replica" : {
                "index" : "myindex", "shard" : 0,
                "node" : "node2"
          }
        }
    ]
}'

响应：

{
  "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
}

试试这个：

curl -XPOST＆＃39; xx.xxx.xx：9200 / _cluster / reroute＆＃39; -d＆＃39; {＆＃34;命令＆＃34; ：[{＆＃34; allocate_stale_primary＆＃34;：{＆＃34; index＆＃34; ：＆＃34; myindex＆＃34;，＆＃34;碎片＆＃34; ：0，＆＃34;节点＆＃34; ：＆＃34; node2＆＃34;，＆＃34; accept_data_loss＆＃34; ：true}}]}＆＃39;

elasticsearch - 没有可用的碎片副本？
