今天ES 服务器，一致处于yellow状态，有节点带分配，看了一下ES的日志，发现LockObtainFailedException 异常，在网上看到解决方案，先close 再open，可以 解决，试了，没用。 无奈重启服务器（非线上），依然相同的错误， 无奈使出杀手锏，手动分配，

curl -XPOST 'localhost:9200/_cluster/reroute' -d '{
        "commands" : [ {
              "allocate" : {
                  "index" : “indexname",
                  "shard" : 2,
                  "node" : "p7hX9aD3STuGUHR-R03UPA",
                  "allow_primary" : true
              }
            }
        ]
    }'

真正的问题显现出来，

[YES(total shard limit disabled: [index: -1, cluster: -1] <= 0)][YES(node passes include/exclude/require filters)][YES(below shard recovery limit of [2])][YES(allocation disabling is ignored)][NO(more than allowed [85.0%] used disk on node, free: [12.726023442766103%])]"},"status":400}

原来是硬盘不够了，哎！ 删除日志，问题解决。
