Check the cloud provider's support for mounting object stores:

• Some cloud providers may not support mounting object stores like GCS without privileged mode.

Use COPY mode as an alternative:

• Manually upload files at the end of the task using gsutil cp.

Consider the following workaround:

resources:
  cloud: runpod

  ...

file_mounts:
  /data:
    source: gs://<bucket-name>
    mode: MOUNT

run: |
  echo hi > mycheckpoint.dat
  gsutil cp mycheckpoint.dat gs://mybucket/

Future improvements:

• Fail early if mounting is not supported on a cloud provider.
• Provide clear error messages when mounting fails.
