你好，

我们已安装一个4节点Nutanix群集。在安装过程中，您必须选择群集冗余因子，RF2或RF3。我们尝试选择RF3，但系统表示您需要至少5个节点。所以我们被迫与RF2创建群集。在未来，我们计划将群集与其他节点扩展，可能只是存储节点。是否有可能从rf2升级到rf3，而无需删除现有群集并创建一个新的群集？

    \nwe have installed a 4 node Nutanix cluster. In the installation process you have to select the cluster redundancy factor, RF2 or RF3. We tried to select RF3 but the system says that you need at least 5 nodes. So we were forced to create the cluster with RF2. In the future we plan to extend the cluster with additional nodes, may be only storage nodes. Will it be possible to upgrade from RF2 to RF3 without having to delete the existing cluster and create a new one?

    对于RF3，我们需要5个节点，因为我们存储5个元数据副本。存储仅节点可以参加元数据圈，因此您可以将群集从RF2升级到RF3。

    是的！一旦您有5个节点，您可以从RF2到RF3无空升级：

    有一个命令要将群集级别从RF2更改为RF3，一旦完成，您也可以将容器设置为RF3。
