我正在尝试部署一个elasticsearch statfulset,并由rookceph storagecclass提供存储。
pod处于挂起模式,原因如下:Warning FailedScheduling 87s default-scheduler 0/4节点可用:4 pod有未绑定的immediate persistentvolumecclaims。
状态集如下所示:

和PVC没有被创建的原因是:
Normal FailedBinding 47s (x62 over 15m) persistentvolume-controller没有可用于此声明的持久卷,也没有设置存储类
你知道我做错了什么吗?
在添加了brook -ceph-block存储类并将其更改为正常工作后,
