FEStorageControllerErrors

This alert is raised when the FE CSI storage controllers are raising errors. Malfunctioning storage controllers prohibit the creation of new volumes by the k8s cluster.

The alert disappears after 30m when the problem is fixed.

Error Resolution

The storage controller pods need to be restarted in order to fix the problem. There are two pods in the kube-system namespace.

Example:

$kubectl -n kube-system get pods|grep csi-controller
everest-csi-controller-5857bdb9fd-95gq8   1/1     Running   0          16h
everest-csi-controller-5857bdb9fd-qwnjd   1/1     Running   0          16h

kubectl -n kube-system delete pod everest-csi-controller-XXXXXXXXXXXX
