【VMware vSAN】主机之间网络性能测试，提示“无法运行网络性能测试。请稍后重试。”的处理过程。

2023-12-07 17:33 由 JUNIOR_MU 发表于 #其他

vSAN集群监控，有一个主动测试功能，里面可以针对vSAN主机进行虚拟机创建测试、网络性能测试等。

官方解释：

虚拟机创建测试通常需要 20 至 40 秒时间，在超时情况下最长需要 180 秒时间。将为每个主机生成一个虚拟机创建任务和一个删除任务，这些任务将显示在任务控制台中。
网络性能测试旨在评估是否存在连接问题以及主机间的网络带宽是否能够满足 vSAN 的要求。

使用该功能需要提前启用 vSAN 性能服务的网络诊断模式，设置路径：vSAN服务配置 - 性能服务 - 网络诊断模式。

现在运行网络性能测试后，平台出现错误，提示“无法运行网络性能测试。请稍后重试。”。

SSH连接到vCenter Shell，进入到/storage/log/vmware/vsan-health目录，查看tail -n 300 vmware-vsan-health-service.log日志，发现以下内容：

从上面日志可以看出，其实在运行网络性能测试后，后台是已经成功执行了的，那为什么平台提示运行错误呢？

我的环境是VMware vSAN 6.7 U3，VMware vCenter 6.7 U3，之前因为VMware vCenter Server高危漏洞做过升级，现在是U3t。

怀疑这可能是个bug......

如果想正常运行网络性能测试，并且展示出来，可以在vCenter右上角，选择我的首选项，将vSphere Client的语言修改为英文或者其他语言，再重新执行即可。

修改语言为英文后，运行正常。

其他补充：
