Is it because there are not enough resources for a new pod on my node and i need to increase it? The emptyDir.medium field controls where emptyDir volumes are stored. The following table lists the available effects: Azure File CSI driver has been rolled back to 1.12 to avoid storage account creation every time when a new Azure file share volume is created.
