GBase 8a GCDW存算分离主机版安装使用-扩容

扩容调度和计算资源

本次将10.0.2.211扩容为调度和计算节点。管理集群gcware当前版本不支持扩容。

注意，扩容调度资源，需要停集群服务。

准备

除了标准要求，安装foundationdb客户端外，还要将foundationdb的配置文件复制到新节点.

 scp /etc/foundationdb/fdb.cluster 10.0.2.212:/etc/foundationdb/

以新节点能运行fdbcli的status正常为准，参考前面的部分。

扩容配置文件

与953扩容相同，注意要增加数据库登录的用户名和密码，genDBUser和genDBPwd。

扩容warehouse

通过向现有warehouse增加节点来完成扩容过程。请参考后面扩容计算资源的对应章节。

扩容计算资源

在已有2个调度节点，2个计算节点的情况下，只扩容10.0.2.212为纯计算资源。前置要求一样，特别是foundationdb的客户端和其配置文件。参考前面准备章节。

配置文件

只增加了dataHost,其它的将现有的节点写上去就行了。

[gbase@rh7_210 gcinstall]$ cat demo_3.options
installPrefix= /opt
coordinateHost =
coordinateHostNodeID = 211
dataHost = 10.0.2.212
existCoordinateHost =10.0.2.210,10.0.2.211
existDataHost =10.0.2.210,10.0.2.211

扩容warehouse

通过gcadmin addnodes将计算节点加入现有warehouse

创建配置文件

[gbase@rh7_210 gcinstall]$ cp gcChangeInfo.xml  gcChangeInfo_extend_212.xml
[gbase@rh7_210 gcinstall]$ vi gcChangeInfo_extend_212.xml
[gbase@rh7_210 gcinstall]$ cat gcChangeInfo_extend_212.xml
<?xml version="1.0" encoding="utf-8"?>
<servers>
    <rack>
        <node ip="10.0.2.212"/>
    </rack>
</servers>
[gbase@rh7_210 gcinstall]$

将新扩容的计算节点加入现有warehouse

[gbase@rh7_210 gcinstall]$ gcadmin addnodes gcChangeInfo_extend_212.xml testwh
gcadmin add nodes ...

flush statemachine success

gcadmin addnodes to wh [testwh] success
