Instructions
在 vSphere 叢集中啟用 vSphere HA，或 ESXi 主機上未安裝容錯網域管理員 （FDM） 代理程式時，故障診斷問題。
事實：
vSphere HA
vSphere 叢集容
錯網域管理員 （FDM） 代理程式。
手續：
- 如果 vSphere HA 未啟用，請執行下列步驟：
- 停用並重新啟用或重新設定叢集上的 vSphere HA。此檢查可解決大部分問題。
- 查看版本資訊，瞭解 vSphere HA 的已知問題，並確認 vSphere 為最新版本。
- 檢查 ESXi 主機上的容錯網域管理員 （FDM） 記錄，並搜尋錯誤訊息。
要在 ESXi 主機上檢閱的記錄，以找出問題原因。
- FDM 作業記錄：
/var/log/fdm.log or /var/run/log/fdm - FDM 代理程式安裝記錄：
/var/log/fdm-installer.log
此問題的可能原因
- vSphere HA 未正確設定。
- 並非所有主機均可存取 vSphere HA 活動訊號的資料存放區。
- FDM 代理未正確安裝在 ESXi 主機上。
- ESXi 主機和 vCenter Server 之間的網路連線中斷。
- ESXi 主機未正確連接至 vCenter Server。
- FDM 代理程式無法安裝在 ESXi 主機上。
如果無法在 ESXi 主機上安裝 FDM 代理程式，請執行下列檢查：
- 檢查 FDM 記錄是否有錯誤：
/var/log/fdm.log - 確認 ESXi 主機和 vCenter Server 之間有足夠的網路頻寬。
- 檢查是否有硬體問題是由網路流量輸送量所造成。
- 檢查 ESXi 主機上的磁碟空間是否可用
/var and /tmp。使用命令：
vdf -h
如果在 ESXi 主機上安裝 FDM 代理程式的問題與網路流量有關，請識別問題的原因：
- 網路介面控制器 （NIC） 的硬體問題
- NIC 速度和交換器速度不相符
- 硬體或防火牆封鎖或減緩流量。
此外，請檢查下列檔案是否存在於 ESXi 主機上，以確認 FDM 代理程式檔案是否已從 vCenter 推到 ESXi 主機： /etc/opt/vmware/fdm 目錄：
- 叢集組態：
Clusterconfig - FDM 組態檔案：
fdm.cfg - 主持人成員資格清單：
Hostlist - 所有虛擬機器 （VM） 及其相容主機的清單：
Vmmetadata
請參閱以下範例螢幕擷取畫面：
圖 1：確認檔案已從 vCenter 推至 ESXi 主機。
