README example fails

[JulienVig]

Hi,
Running the following example in Section 3 fails with an error:

runai submit \
  --name setup-test-storage \
  --image ubuntu \
  --pvc mlo-scratch:/mloscratch \
  -- ls -la /mloscratch/homes

The logs show the following:

runai-rcp logs setup-test-storage
ls: cannot open directory '/mloscratch/homes': Permission denied

I'm not sure why this example now fails as it used to work in the past.
