如何解决如何为 Redhat 集群创建软件防护代理
我刚刚在我的电脑上用 RHEL 7.9 创建了一个具有三个节点的虚拟 Redhat 集群：
rhel79_a
rhel79_b
rhel79_c
我想使用围栏，但我想我需要一些帮助。
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服务器来创建防护设备？必须如何创建它？
