I recalculated disk usage and it is still pretty high: 232.5 GB
You are also using two accounts, which is a more immediate problem.
You should write in to galaxy-bugs@lists.galaxyproject.org immediately so that we can sort out your duplicated accounts before they are both picked up and deleted. Once that is resolved, we can figure out why you are unable to permanently delete data, privately via email.
This is what happens when duplicated accounts are monitored by a human (no data loss and consolidation is possible).
When duplicates are detected by automated processes, it usually results in full data loss, as noted in all account activation emails. Quote:
By clicking on the above link and opening a Galaxy account you are also confirming that you have read and agreed to Galaxy’s Terms and Conditions for use of this service (https://usegalaxy.org/static/terms.html). This includes a quota limit of one account per user. Attempts to subvert this limit by creating multiple accounts or through any other method may result in termination of all associated accounts and data.
Let’s fix this, now and fast.
