es重启保留原有分分片模式

环境:

Os:Centos 7

ES:6.5.8

 

1.查看当前的分片情况

[elasticsearch@host134 bin]$ curl -u elastic:elastic -X GET "192.168.1.134:19200/_cat/shards/metric_pl?v&h=shard,prirep,node,docs,store"
shard prirep node      docs store
2     p      node-135 19936 1.7mb
2     r      node-14  19936 1.7mb
1     p      node-135 19976 1.7mb
1     r      node-134 19976 1.7mb
3     p      node-14  20038 1.7mb

0     p      node-14  20063 1.7mb

 

查看当前的节点角色

[elasticsearch@host134 bin]$ curl -u elastic:elastic http://192.168.1.134:19200/_cat/nodes?v
ip            heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name

2.设置参数

curl -u elastic:elastic -X PUT "192.168.1.134:19200/_cluster/settings?pretty" -H 'Content-Type: application/json' -d'
{"transient" : {"cluster.routing.allocation.enable": "none"}
}
'

 

3.停掉主节点
192.168.1.14
查看当前节点角色

[elasticsearch@host134 bin]$ curl -u elastic:elastic http://192.168.1.134:19200/_cat/nodes?v
ip            heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name

4.重新启动
查看节点角色

[elasticsearch@localhost bin]$ curl -u elastic:elastic http://192.168.1.134:19200/_cat/nodes?v
ip            heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name

查看分片

[elasticsearch@localhost bin]$ curl -u elastic:elastic -X GET "192.168.1.134:19200/_cat/shards/metric_pl?v&h=shard,prirep,node,docs,store"
shard prirep node      docs store

0     p      node-135 20063 1.7mb
0     r 

 

5.恢复参数

curl -u elastic:elastic -X PUT "192.168.1.134:19200/_cluster/settings?pretty" -H 'Content-Type: application/json' -d'
{"transient" : {"cluster.routing.allocation.enable": "all"}
}
'

再次查看分片情况

[elasticsearch@host134 bin]$ curl -u elastic:elastic -X GET "192.168.1.134:19200/_cat/shards/metric_pl?v&h=shard,prirep,node,docs,store"
shard prirep node      docs store
2     p      node-135 19936 1.7mb
2     r      node-14  19936 1.7mb
3     r      node-14  20038 1.7mb
3     p      node-134 20038 1.7mb
1     p      node-135 19976 1.7mb
1     r      node-134 19976 1.7mb
4     r      node-14  19987 1.7mb
4     p      node-134 19987 1.7mb
0     p      node-135 20063 1.7mb
0     r      node-14  20063 1.7mb

与原来的比较,发现保持一致,下面是原来的:[elasticsearch@host134 bin]$ curl -u elastic:elastic -X GET "192.168.1.134:19200/_cat/shards/metric_pl?v&h=shard,prirep,node,docs,store"
shard prirep node      docs store
