使用三台虛擬機器和兩台裸機(bare metal)安裝openshift 4.17時，出現下列的log
updated status from known to insufficient (Host cannot be installed due to following failing validation(s): Host clock is not synchronized, service time is ahead of host’s at least for 20.0 minutes, please configure an NTP server via DHCP. Service time: 2025-03-28 03:29:28.867434383 +0000 UTC ; Host couldn’t synchronize with any NTP server)
透過ssh登入其中一台虛擬機器檢查，發現系統時間比當前時間還要快
1 | sudo hwclock -v |
進一步確認ESXi Host的時間設定，發現和虛擬機器一樣，有時間較快的狀況
1 | esxcli hardware clock get |
確認後，決定使用NTP服務修正ESXi Host的時間
並在該虛擬機器的設定中，開啟主客體時間同步的設定
