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
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 startvolume rebalance: data: success: Rebalance on data has been started successfully. Use rebalance status command to check status of the rebalance process. ID: 2e213ca1-206c-49bd-8381-93bd1ea5195f
