前段时间，我在单节点k3s集群上用rook创建了一个ceph集群，就是为了试一试，效果很好。我能够通过 cephfs 为其他 pod 提供存储空间。我按照 rook quickstart 文档中给出的示例来执行此操作。
然而，两天前，在我没有任何干预的情况下，ceph 集群停止了工作。ceph manager pod 似乎有一个问题：我的 podrook-ceph-mgr-a-6447569f69-5prdw在循环中崩溃，这是它的事件：

不知道failed to sync secret cache是原因还是结果。是车问题还是k3s问题？
没有输出k3s kubectl logs rook-ceph-mgr-a-6447569f69-5prdw -n rook-ceph（添加 -p 没有任何改变）
谢谢你的帮助，这是我关于stackoverflow的第一个问题，希望它是正确的:)
