Hi Team, I had performed an upgrade of my Galaxy server and had experienced an issue with some of the database / metadata files have been corrupted. I have found instances where the dataset exists, but cannot be detected or read by galaxy when attempting to analysis data from a history. In some cases I have been able to locate another copy and replace the damaged file. What might have been the cause and is there a way to resolve it? Is this a possible Postgres issue or since the metadata is contained in the /database/files/ directory an artifact of the upgrade?
