What this manual trying to resolve

1. You had a running rook/ceph cluster, suddenly your Kubernetes environment exploded, you have to start a new Kubernetes environment and put your existing rook/ceph cluster back.

背景

幻想乡又发生了一场新的异变。 说是异变也不完全准确，倒不如说，似乎又是“某人”因为闲着无聊而发起的无伤大雅的玩笑呢。 希望快点解决异变然后回家喝茶的，莫名其妙被卷入或是兴致勃勃站在“某人”一方的，乃至别有用心想要大闹一番的——当这些少女汇集在一起的时候，一场华丽的弹幕战，即将开幕！
