昨天的服务很好。但是今天当我检查服务的状态时,我看到:
Mar 11 14:03:16 coreos-1 systemd[1]: scheduler.service: main process exited, code=exited, status=2/INVALIDARGUMENT
Mar 11 14:03:16 coreos-1 systemd[1]: Unit scheduler.service entered failed state.

真的很困惑,因为 etcd、flannel 和 apiserver 工作正常。
etcd 只有一些奇怪的日志:
Mar 11 20:22:21 coreos-1 etcd[472]: [etcd] Mar 11 20:22:21.572 INFO | aba44aa0670b4b2e8437c03a0286d779: warning: heartbeat time out peer="6f4934635b6b4291bf29763add9bf4c7" missed=1 backoff="2s"

所以,我真的被卡住了,不知道出了什么问题。我该如何解决这个问题?或者,我如何查看调度程序的详细信息日志。
journalctl
给我同样的日志systemd status
