原因分析

  1. 查看DBService的备份页面错误信息,有如下错误信息提示:
    Clear temporary files at backup checkpoint DBService_test_DBService_DBService_20180326155921 that fialed last time.
    Temporyary files at backup checkpoint DBService_test_DBService_DBService20180326155921 that failed last time are cleared successfully.

  2. 查看/var/log/Bigdata/dbservice/scriptlog/backup.log文件,发现日志停止打印,并没有备份相关信息。
  3. 查看主 OMS 节点 /var/log/Bigdata/controller/backupplugin.log日志发现如下错误信息:
    result error is ssh:connect to host 172.16.4.200 port 22 : Connection refused (172.16.4.200是DBService的浮动IP)
    DBService backup failed.
