影響

IO 不受影響，這些錯誤是可重試的。尖峰 I/O 流量可能會導致效能下降

叢集中的其中一個 ESXi 主機設定錯誤 - VMFS。未設定 HardwareAcceleratedLocked。

在 vSphere 中，可以為每個檔案系統或全域啟用 ATS 鎖定。在這種情況下，叢集中的所有主機都有其所有 VMFS 資料存放區的相符設定 （僅限 ATS），但有一個主機已全域停用：

[root@ESXI01:~] cat /etc/vmware/esx.conf |grep HardwareAcceleratedLocking
/adv/VMFS3/HardwareAcceleratedLocking = "0"

為了進行比較，已正確設定每個資料存放區的鎖定 （ATS）：

因應措施

在進階設定中啟用硬體加速鎖定。
