在kubectl应用-f cluster.yaml(来自rook GitHub存储库的Yaml示例文件)后，即使我等待了1个小时，我也只能运行一个pod rook-ceph-mon-a-***。我该如何调查这个问题？
NAME READY STATUS RESTARTS AGE
rook-ceph-mon-a-7ff4fd545-qc2wl 1/1 Running 0 20m
在单个正在运行的Pod的日志下方
$ kubectl logs rook-ceph-mon-a-7ff4fd545-qc2wl -n rook-ceph

最佳答案
假设您已遵循rook的Github页面here上的官方ceph-quickstart指南，请首先使用以下命令检查有问题的Pod:
kubectl -n rook-ceph get pod
并使用以下命令从中检索日志:
kubectl logs <pod_name>
请更新您的原始问题以包括这些命令输出。
