教程:将群集节点添加到 Azure FXT Edge Filer 群集Tutorial: Add cluster nodes to an Azure FXT Edge Filer cluster

仅使用一个节点创建新的 Azure FXT Edge Filer 群集。A new Azure FXT Edge Filer cluster is created with only one node. 在进行其他配置之前,应至少再添加两个节点并启用高可用性。You should add at least two more nodes and enable high availability before doing other configuration.

本教程介绍如何添加群集节点并启用高可用性(HA)功能。This tutorial explains how to add cluster nodes and enable the High Availability (HA) feature.

本教程介绍:In this tutorial, you will learn:

  • 如何将节点添加到 FXT 群集How to add nodes to the FXT cluster
  • 如何启用 HAHow to enable HA

本教程中的步骤大约需要 45 分钟才能完成。The steps in this tutorial take approximately 45 minutes to complete.

在开始本教程之前,请打开要添加的节点并设置其初始密码Before you start this tutorial, power on the nodes that you want to add and set their initial passwords.

1.加载“群集节点”页面1. Load the Cluster Nodes page

在 Web 浏览器中打开群集的控制面板,然后以管理员身份登录。Open the cluster's Control Panel in a web browser, and sign in as an administrator. (详细说明位于概述文章的打开设置页面下。)(Detailed instructions are in the overview article, under Open the Settings pages.)

控制面板在打开时显示“仪表板”选项卡 。The Control Panel shows the Dashboard tab when it opens.

控制面板仪表板(第一个选项卡)

此图显示了新创建的具有单个节点的群集的仪表板。This image shows the dashboard of a newly created cluster, with a single node.

2.找到要添加的节点2. Locate the node to add

若要添加节点,请单击“设置”选项卡,在“群集”部分选择“FXT 节点”页面 。To add nodes, click the Settings tab and choose the FXT Nodes page in the Cluster section.

控制面板“设置”选项卡(第二个选项卡),其中已加载“群集”>“FXT 节点”

“FXT 节点 - 未连接”列表显示了所有未分配的 FXT 节点(大多数数据中心只有几个这样的节点) 。The FXT Nodes - Unjoined list shows all unassigned FXT nodes (most data centers have only a few. 找到想要添加到群集的 FXT 节点。Find the FXT nodes that you want to add to the cluster.

提示

如果在“未加入”列表中找不到所需的节点,请检查它是否满足以下要求 :If you cannot find the node you want on the Unjoined list, check that it meets these requirements:

  • 它已启动并已设置 root 密码It is powered on and has had a root password set.

  • 它已连接到你可以访问的网络。It is connected to a network you can access. 如果使用 VLAN,则它必须与群集位于同一 VLAN 中。If you use VLANs , it must be on the same VLAN as the cluster.

  • 可以使用 Bonjour 协议检测到它。It can be detected with the Bonjour protocol.

    某些防火墙设置会阻止 Bonjour 使用的 TCP/UDP 端口,从而阻止 FXT 操作系统自动检测节点。Some firewall settings block the TCP/UDP ports used by Bonjour, which prevents the FXT operating system from automatically detecting the nodes.

如果要添加的节点不在列表中,请尝试以下解决方案:If the node that you want to add isn’t on the list, try these solutions:

  • 单击“手动发现”按钮,按 IP 地址查找它 。Click the Manual Discover button to find it by IP address.

  • 手动分配临时 IP 地址。Manually assign temporary IP addresses. 这种情况很少见,但如果使用标记的 VLAN 并且节点不在正确的网络上,或者网络不允许自我分配的 IP 地址,则可能需要这样做。This is rare but might be needed if you use tagged VLANs and the nodes are not on the correct network, or your network does not allow self-assigned IP addresses. 按照本文档旧版本中的说明手动设置静态 IP 地址Follow the instructions in the legacy version of this document to manually set a static IP address.

节点名称、IP 地址、软件版本和资格状态显示在列表中。The node name, IP address, software version, and eligibility status are displayed in the list. 通常,“状态”列会显示“要加入”或描述导致节点无法加入群集的系统或硬件问题 。Typically, the Status column either says “Wants to join” or describes a system or hardware problem that makes the node ineligible to join the cluster.

“操作”列包含一些按钮,可用于将节点添加到群集或更新其软件 。The Actions column has buttons that let you add the node to the cluster or update its software. 更新按钮会自动安装与群集中已有节点匹配的软件版本。The update button automatically installs the software version that matches the nodes already in the cluster.

群集中的所有节点都必须使用相同版本的操作系统,但在添加节点之前无需更新软件。All of the nodes in a cluster must use the same version of the OS, but you don’t need to update software before adding a node. 单击“允许加入”按钮后,群集加入过程将自动检查并安装与群集上的版本匹配的操作系统软件 。After you click the Allow To Join button, the cluster join process automatically checks and installs the OS software that matches the version on the cluster.

若要详细了解此页面上的选项,请参阅群集配置指南中的“群集” > “FXT 节点”To learn more about the options on this page, read Cluster > FXT Nodes in the Cluster Configuration Guide.

3.单击“允许加入”按钮3. Click the "Allow to Join" button

单击要添加的节点的“操作”列中的“允许加入”按钮 。Click the Allow To Join* button in the Actions column for the node that you want to add.

单击该按钮后,节点的软件可能为准备将其添加到群集中而更新,其状态也会随之更新。After you click the button, the node's status might change as its software is updated in preparation for adding it to the cluster.

下图显示了正在加入群集(最有可能的是在加入前进行操作系统更新)的节点。The image below shows a node that is in the process of joining the cluster (most likely, it’s getting an OS update before being added). 对于正在添加到群集的节点,“操作”列中不显示任何按钮 。No buttons appear in the Actions column for nodes that are in the process of being added to the cluster.

节点表的一行,显示了节点的名称、IP 地址、软件版本、“允许加入”消息和空白的最后一列

几分钟后,新节点应出现在 FXT 节点设置页面顶部的群集节点列表中 。After a few moments, the new node should appear in the list of cluster nodes at the top of the FXT Nodes settings page.

重复此过程以将其他节点添加到群集。Repeat this process to add the other nodes to your cluster. 无需等待一个节点完成加入群集的过程,即可开始加入下一个。You don’t need to wait for one node to finish joining the cluster before starting another.

启用高可用性Enable High Availability

将第二个节点添加到群集后,可能会在控制面板仪表板上看到一条警告消息,指出未配置高可用性功能。After you’ve added a second node to your cluster, you might see a warning message on the control panel Dashboard that the high availability feature is not configured.

高可用性(HA)允许群集节点在发生故障时相互补偿。High availability (HA) allows the cluster nodes to compensate for each other if one goes down. 默认情况下不启用 HA。HA is not enabled by default.

“仪表板”选项卡,“条件”表中显示了“群集有多个节点,但未启用 HA…”消息。

备注

群集中的节点少于三个时不要启用 HA。Do not enable HA until you have at least three nodes in the cluster.

按照此过程打开 HA:Follow this procedure to turn on HA:

  1. 在“设置”选项卡的“群集”部分,加载“高可用性”页面 。Load the High Availability page in the Cluster section of the Settings tab.

    HA 配置页面(“群集”>“高可用性”)。

  2. 单击标记为“启用 HA”的框,然后单击“提交”按钮 。Click the box labeled Enable HA and click the Submit button.

“仪表板”上将显示一条警报,确认已启用 HA 。An alert appears on the Dashboard to confirm that HA is enabled.

仪表板上会显示一条消息,“HA 已完全配置”

后续步骤Next steps

添加群集中的所有节点后,配置群集的长期存储以继续设置。After adding all of the nodes in your cluster, continue the setup by configuring your cluster's long-term storage.
