Unable to start mongo server due to corrupted admin database

Hello,

We have an instance of mongo which does not start up anymore due to corrupted data, the root cause seems to be unclean shutdown. I tried using the --repair option but it did not help. Here is the error I see in the log files:

Fatal assertion 28548 NoSuchKey Unable to find metadata for table:admin/collection-184-1679902527159703400

I did find a related issue https://jira.mongodb.org/browse/SERVER-28364. The final comment seem to indicate there is nothing that could be done. But I just wanted to see if anything has changed since then. Is there anything that could done to recover this database (admin). Our other databases contain sensitive data, but since this is just the admin database, I was wondering if I upload this securely so that somebody from mongo can take a look (don't want to just attach it here)?

Please let me know your thoughts!
