Troubleshooting

• MountVolume.SetUp failed for volume due to multipathd on the node
• Pod stuck in creating state when Longhorn volumes filesystem is corrupted
• If provisioning of volumes fails continuously, it often helps to kill the pods of the csi-attacher and csi-provisioner DaemonSets. Once they're recreated, the Kubernetes API can interface with the CSI driver again
