TrueNas OneDrive Cloudsync corrupted on transfer

This is a quick one, if you get the following error or similar:

2021/06/07 00:15:35 ERROR : Attempt 3/3 failed with 1 errors and: corrupted on transfer: sizes differ 189118 vs 130560
2021/06/07 00:15:35 Failed to copy: corrupted on transfer: sizes differ 189118 vs 130560

These track back to an issue with OneDrives metadata generation altering the size of the file. You can see details on this issue here: https://github.com/rclone/rclone/issues/399

To resolve this you need to add --ignore-size to the rclone config that TrueNas creates.

While the UI doesn’t expose a extra-args field, it is present in the underlying database. This post guides you through how to add additional args: https://www.truenas.com/community/threads/cloud-sync-task-add-extra-rclone-args-to-specify-azure-archive-access-tier.85526/

For this OneDrive error the following works: (Assuming you only have 1 cloudsync task ID == 1)

$ sqlite3 /data/freenas-v1.db
update tasks_cloudsync set args = "--ignore-size" where id = 1;

You can double check the change with the following

sqlite> .headers on
sqlite> select * from tasks_cloudsync;

Then it’s just a case of re-running the task in the UI and 🎉

Standard
