我按照here的说明，昨天从Opscenter 5.2.0升级到6.0.7（这是DSE 4.8.10）。升级后，我注意到所有计划的备份作业都丢失了。备份服务的“活动”选项卡永远加载并给了我一些超时错误。我在opscenterd.conf中添加了一个超时来解决这个问题。
[ui]
default_api_timeout=400
然后我添加了我的简单预定作业 - 每日备份服务器，2个列系列。我保存了这份工作，然后把它安排到＆＃34;立即运行＆＃34;。备份失败，并显示以下错误：
Failed query to http://10.0.30.161:61621/ops/take-snapshot?req-id=78c53af6-bc02-49f2-b9a2-89452ec91cc9 : The http request to the agent timed out. This most likely indicates that you need to restart the agent on this node.
根据Opscenter UI，所有代理都已启动。我在升级期间错过了什么吗？或者6.0.7是否存在已知问题？
编辑：我在agent.log
