oVirt 4.4.10三节点超融合集群安装配置及集群扩容(二)_ovirt超融合

在上节安装完成3节点集群后，在此基础上扩容到6节点<oVirt每次扩容后的容量必须是3的倍数>

操作步骤

1. 在原始第一台服务器访问https://192.168.5.100:9090/,在"Virtualiztion"->“Hosted Engin"下点击"Manage Gluster”
   
   点击"Expand Cluster"
   
   填写新加入的3个节点的FQDN，然后点击"下一步"开始安装glusterfs
   

此处根据需要添加是只扩容data，还是需要扩容所有的如data, vmstore, engine

2. gfs安装完成之后到engine管理页面新增主机
3. 在数据中心将data设置为维护状态

4. 在存储域中选中data域后点击管理域

5. 修改挂载选项，将新加入的gfs节点加入原有参数后边，然后再重新激活data域

6. 重新平衡数据，即将原有数据平衡分布到新添加的brick中

[root@node100 data]# gluster volume rebalance data start
volume rebalance: data: success: Rebalance on data has been started successfully. Use rebalance status command to check status of the rebalance process.

查看rebalance状态

[root@node240 glusterfs]# gluster volume rebalance data status
                                    Node Rebalanced-files          size       scanned      failures       skipped               status  run time in h:m:s
