Bacula:主管与 SD 的此工作连接已丢失

Question

SD-7.4.4(ubuntu 16)Director-7.4.4(ubuntu 16)FD-5.2.10(Windows)

我在使用 Bacula 备份 Windows 客户端时遇到问题。当备份大小约为 1MB 或 2 时，我可以很好地运行备份，但是当运行 500MB 的备份时，我每次都会遇到相同的错误

"Director's connection to SD for this Job was lost."

有些事情要提一下。当我发出status client时:

Terminated Jobs:  JobId  Level    Files      Bytes   Status   Finished
======================================================================
    81  Full      5,796    514.8 M  OK       06-Nov-17 12:50 BackupComputerA

当我发出status dir时

06-Nov 17:58 acme-director JobId 81: Error: Director's connection to SD for this Job was lost.

备份大约 5 分钟后，我收到一条消息:

作业完成并终止，但随后失去连接，我从未得到

"OK"

状态更新。

我添加了"Heartbeat Interval = 1 Minute"对于所有的守护进程，仍然没有运气。在Director上使用mysql作为数据库

感谢您的帮助

对于遇到同样问题的人，我可以通过向客户端添加心跳间隔并调整保持事件时间来解决 SD 和主管之间的问题

sysctl -w net.ipv4.tcp_keepalive_time=60

在存储守护进程和 Controller 上。使用 bconsole 远程连接到主管也会中断作业，因此我在与主管相同的计算机上运行 bconsole 并通过 ssh 连接。
