Why is my persistent disk failing to mount to my pod? - kubernetes

Question

I've been trying to find out why my pod won't start up, when I go to describe it I get this:
Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Normal Scheduled 2m default-scheduler Successfully assigned my-namespace/nfs to gke-default-pool
Normal SuccessfulAttachVolume 2m attachdetach-controller AttachVolume.Attach succeeded for volume "nfspvc"

When I describe the compute disk, all looks good:

Updates are available for some Cloud SDK components. To install them,
please run:
$ gcloud components update
And here is my pods manifest:
apiVersion: extensions/v1beta1
kind: Deployment

volumeMounts:

volumes:

I'm not really sure what 'MountVolume.MountDevice failed for volume "nfspvc" : executable file not found in $PATH' means, or what else I should look in to, to investigate the source of the issue?
If it makes any difference, this is created by a script, the ordering of which is:
Create the compute disk
Run helm, which in turn creates the above deployment, service, persistent volume, and persistent volume claim.

Answer 1

fsType: ext4i
Try removing that 'i'.
