Couchbase重新平衡不匹配

标签： couchbase

配置我的群集后，使用cuchbase Rest API，当我想添加新节点，然后重新平衡时，我遇到了问题。

我正在做什么

为机器A创建帐户和群集

createAccount(){
    ip=$1
    curl -s -u ${USER}:${PASSWORD} -X POST http://${ip}:8091/pools/default -d memoryQuota=${QUOTA} }

createCluster(){
    ip=$1
    # Initialize Node
    curl  -u ${USER}:${PASSWORD} -v -X POST http://${ip}:8091/nodes/self/controller/settings \
      -d 'data_path=%2Fopt%2Fcouchbase%2Fvar%2Flib%2Fcouchbase%2Fdata& \
      index_path=%2Fopt%2Fcouchbase%2Fvar%2Flib%2Fcouchbase%2Fdata'

    # Rename Node
    curl  -u ${USER}:${PASSWORD} -v -X POST http://${ip}:8091/node/controller/rename \
      -d 'hostname=127.0.0.1'

    # Setup Services
    curl  -u ${USER}:${PASSWORD} -v -X POST http://${ip}:8091/node/controller/setupServices \
      -d 'services=kv%2Cn1ql%2Cindex'

    # Setup Administrator username and password
    curl  -u ${USER}:${PASSWORD} -v -X POST http://${ip}:8091/settings/web \
      -d "password=$PASSWORD&username=$USER&port=SAME"

}

为机器B创建帐户和群集（与上面相同的脚本）

然后添加服务器B呼叫服务器A 

addServer(){
    curl -u ${USER}:${PASSWORD} http://A:8091/controller/addNode \
          -d "hostname=B&user=$USER&password=$PASSWORD&services=kv%2Cn1ql%2Cindex"

}

然后我可以看到A和B服务器中的B如何等待重新平衡。 但是当我尝试重新平衡呼叫A

时 
rebalance(){
    masterIp=$1
    couchbaseNode=$2
    curl -v  -u ${USER}:${PASSWORD} -X POST http://A:8091/controller/rebalance \
    -d "knownNodes=ns_1@A, ns_1@B"
 }

服务器返回

  {"mismatch":1}

我在这里做错了什么？

此致

正如您所看到的，最后一个请求因400代码而失败

1 个答案:

答案 0 :(得分：1)

在knownNodes列表中，删除节点之间的空格。我能够复制它。使用空格，{“mismatch”：1}。没有空格，它就有效。

我在这个问题的文档上打开了一个错误。
