[bug\_fix] FailedMount: unable to mount volume into pod

Verify the volume still exists and is reachable from the node. Confirm the StorageClass, CSI driver, or in-tree plugin is installed and running. Check mount options, filesystem type, and node IAM permissions. For NFS, ensure \`rpcbind\` and \`nfs-common\` are installed on the node and the export is accessible.

Journey Context:
A pod stays in ContainerCreating. \`kubectl describe pod\` shows "MountVolume.SetUp failed for volume ... : mount failed" or "timed out waiting for the condition". The PVC is Bound, but the node cannot reach the NFS server due to a security-group change. After opening the port and installing \`nfs-common\` on the worker node, the volume mounts and the pod starts. The fix works because kubelet delegates volume mounting to a plugin; if the storage backend is unreachable, the plugin cannot complete the mount, so the container never starts.
