问题描述

当 ndmpcopy 在 SSH 上运行时,无论重试次数如何,它始终在配置的 SSH 超时时间段(例如,10 分钟)后停止:

  • 在源端控制台上,报告了  Write to socket failed
  • 在目标端控制台上,报告了 interrupted due to an abort
  • 在源端 backup log  中观察到转储正常进行,然后使用 Error (Write to socket failed) 或类似方法中止。
  • 检查备份日志中  Phase_change 和  Error 行的时间戳,这两个事件之间的经过时间将是多次尝试中的一致间隔。 
    • 例如,Phase_change 和 error/abort 之间的经过时间始终为 15 分钟(或其他一些典型的超时值)。
  • ndmpd 日志与调试级别
