確認 ntp 與 ntpq -pn 顯示在可疑節點上的連線已拒絕。 
編輯的輸出僅顯示受影響的節點：
 

admin@utility:~/>: mapall --noerror '/usr/sbin/ntpq -pn'
Using /usr/local/avamar/var/probe.xml

(0.3) ssh -q  -x  -o GSSAPIAuthentication=no admin@192.168.255.5 '/usr/sbin/ntpq -pn'
/usr/sbin/ntpq: read: Connection refused

當您直接在受影響的節點上確認狀態時，我們會發現 ntpd 正在使用中：啟用 （自動重新開機） （結果：資源）：
  
root@node03:~/>: systemctl status ntpd
● ntpd.service - NTP Server Daemon
   Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled)
  Drop-In: /run/systemd/generator/ntpd.service.d
           └─50-insserv.conf-$time.conf
   Active: activating (auto-restart) (Result: resources) since Fri 2022-09-23 13:22:35 UTC; 1min 58s ago

但是狀態應該會反映作用中：作用中 （執行中）：
  
root@node03:~/#: systemctl status ntpd
● ntpd.service - NTP Server Daemon
   Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled)

           └─50-insserv.conf-$time.conf
   Active: active (running) since Fri 2022-09-23 14:04:37 UTC; 26s ago

嘗試啟動 ntpd 失敗：
  
root@node03:~/#: systemctl start ntpd.service
Job for ntpd.service failed because a configured resource limit was exceeded. See "systemctl status ntpd.service" and "journalctl -xe" for details.

檢閱 journalctl -xe 時，會看到「裝置上沒有剩餘空間」的訊息。

df 顯示 /var 為 100%：

/dev/sda7       2.0G  2.0G     0 100% /var 


 

Cause

/var/lib/ntp/drift/ntp.drift 上的 ntpd reliies，其中包含頻率錯誤的最新預估。如果 /var 為 100%，則 ntpd 無法更新或建立 ntp.drift 檔案，而 ntp 無法正常運作。

Resolution

在受影響的節點上，調查並解決 /var 100% 的使用率。修正後重新開機 ntpd：
  
root@node03:~/#: systemctl restart ntpd
 
注意：成功重新開機不會產生任何輸出。

檢查 ntpd 的狀態：
  
root@node03:~/#: systemctl status ntpd

應觀察類似以下結果：
  
root@node03:~/#: systemctl status ntpd

使用 ntpq 驗證 ntp：
  
root@node03:~/#: /usr/sbin/ntpq -pn

應觀察類似以下結果：
