OSError input/output error when writing to mounted filesystem

问题

I have created Google Cloud Storage Bucket and mounted it to my VM using:
gcsfuse my-bucket /path/to/mount/point
When I type df -H its listed as mounted filesystem.
I have the following issue:

If I upload file to the bucket using the GCP web console I can see it from the VM. If I try to create a directory however from the VM to the mounted file system mkdir /path/to/mount/point/test it says:

mkdir: cannot create directory ‘/path/to/mount/point/test’: Input/output error

回答1:

I found the cause. I enabled the debug options as others suggested. Thank you. Unfortunately the logs did not tell me much. Fortunately I had one more VM and I tested there and it worked fine (mount + read/write to bucket). I understood its not the permissions on the bucket side. The VM was created with "Allow default access" which gives readonly to "Storage". I granted read/write to store. One can specify also "Allow full access to all Cloud APIs" although its better not to grant all permissions if you do not need them.

Try to use following command,and it will show more information.

gcsfuse --foreground --debug_gcs --debug_http \
        --debug_fuse --debug_invariants \
        --key-file=/src/gcloud_service_account.json \
        my-bucket /path/to/mount/point

You might see such error message

"code": 403, "message": "Access Not Configured. The API (Cloud Storage JSON API) is not enabled for your project. Please use the Google Developers Console to update your configuration."

If so , you need to enable this API for this instance.
