Instructions

維護活動後,程序可能無法自動啟動。

可能會注意到下列警示:

Event : Process <Process Name> of service <Service Name> has failed to restart after multiple attempts
Example:
Process isi_healthcheck of service isi_healthcheck has failed to restart after multiple attempts

通常,該過程會自動重新啟動。萬一程序未自動重新開機,手動重新啟動程序通常便可解決問題。


確認程序是否正在執行中:

  1. 在叢集的任何節點上開啟 SSH 連線,然後使用 root 帳戶登入
  2. 檢查程序目前是否 正在顯示錯誤訊息的節點上執行。
# isi_for_array -n <Node Numeber> 'ps auxwww | grep -i <Process name> | grep -v grep'
Where <Node Number> is the Node on which the process is not running.
# isi_for_array -n1 'ps auxwww | grep isi_healthcheck | grep -v grep'


如果程序正在執行中:

  1. 使用下列命令取得群組 ID:

# isi event groups list
  1. 清除警示:
# isi event groups modify --resolved=yes --ignore=yes --id=<Group ID from Step #1>


如果程序並非在執行中:

根據過程的不同,重新啟動進程的確切過程可能會有所不同。如需手動重新啟動程序的協助,請聯絡 Dell 技術支援 部門。  


警示:如果服務在錯誤的節點上錯誤地重新開機,可能會發生嚴重問題。
