查看分区
curl 'localhost:9200/_cat/shards?v'




curl -XGET 'http://localhost:9200/_cat/shards' | grep INIT




修复unsigned 分区
for shard in $(curl -XGET http://localhost:9200/_cat/shards | grep UNASSIGNED | grep goods_v1 |awk '{print $2}'); do
    curl -XPOST 'localhost:9200/_cluster/reroute' -d '{
        "commands" : [ {
              "allocate" : {
                  "index" : "goods_v1", 
                  "shard" : $shard, 
                  "node" : "n_4.216", 
                  "allow_primary" : false
              }
            }
        ]
    }'
    sleep 5
done


curl -XPOST 'localhost:9200/_cluster/reroute' -d '{
        "commands" : [ {
              "allocate" : {
                  "index" : "goods", 
                  "shard" : 2, 
                  "node" : "n2", 
                  "allow_primary" : false
              }
            }
        ]
    }'




索引修复
java -cp lucene-core-4.10.4.jar -ea:org.apache.lucene... org.apache.lucene.index.CheckIndex /opt/elasticsearch-1.5.0/data/elasticsearch/nodes/0/indices/goods_v2/2/index -fix
