Grafana Pod - Init:CrashLoopBackOff

S

I have freshly installed K10 and after the installation Grafana works and after a restart (Of the Cluster or Pod) I get the following error message. Can anyone explain this to me? 

pod/k10-grafana-856b5d6b5f-nqczn         0/1     Init:CrashLoopBackOff

@Smugness2774 Thank you for posting this question.

While looking at the event messages, the attach-detach controller is failing to attach the volume to the node where `k10-grafana` pod is scheduled.

Do you still see the older instance of K10-grafana pod in terminating state ?

Sry for the late reply, but no… Also, using another storage class doesn't work. Also, reinstalling the whole thing doesn’t change anything.
