VSAN 节点系统安装时需要注意无论是缓存盘还是容量盘都不要有分区信息。所以每次安装完系统,配置完网络,在加入集群之前,先登录节点web,查看磁盘是否有分区信息,如果有,按照下图方式删掉。如果已经加入到集群,发现有分区信息是不容易删掉的。(最佳实践总结)
方法一:
这个方法经实践总结髌骨不是十分靠谱,哪怕看不到分区,如果执行clear有报错,可能还有问题

方法二:
登录shell,使用command,只要naa.500xxxx这样的磁盘看不到分区信息,说明就没有分区

[root@vsannode01:/dev/disks] ls

该方法对应的清除分区的方法:

[root@vsannode:/dev/disks] partedUtil delete naa.5000c500a05432e7 1

方法三:
将节点加入到vsan,通过查看vsan集群的磁盘管理,如果看到的磁盘数量合格,说明没有磁盘有分区问题
