cluster-computing - 如何为 Redhat 集群创建（软件）防护代理

Question

我刚刚在我的电脑上创建了一个带有 RHEL 7.9 的虚拟 Redhat 集群，其中包含三个节点：

rhel79_a
rhel79_b
rhel79_c

我想使用围栏，但我认为我需要一些帮助。

我尝试使用以下命令创建围栏（fence_virt 类型）：

pcs stonith create fence_rhel79_a_virt fence_virt port="rhel79_a" pcmk_host_list="rhel79_a"
pcs stonith create fence_rhel79_b_virt fence_virt port="rhel79_b" pcmk_host_list="rhel79_b"
pcs stonith create fence_rhel79_c_virt fence_virt port="rhel79_c" pcmk_host_list="rhel79_c"

但正如我所想，缺少了一些东西。确实 pcs status 命令给出了以下错误：

fence_rhel79_a_virt    (stonith:fence_virt):   Stopped
fence_rhel79_b_virt    (stonith:fence_virt):   Stopped
fence_rhel79_c_virt    (stonith:fence_virt):   Stopped

我是否必须创建一个新的服务器来创建一个隔离设备？必须如何创建它？

先感谢您
