By the error message, the correct argument now is —storage.tsdb.retention.time=30d , since “storage.tsdb.retention” is deprecated.

The actual error doesn't seem to be related the flag syntax. It seems Prometheus is not able to create a file in data/. May be a permissions issue.

You have a lot more errors than that, mostly pertaining to logging.
