Corrupted database

Hello,

We have an application that uses mongodb and the database has crashed.
Unfortunately no backup was set up so I’ve been tasked with trying to repair the DB.

The DB uses mongodb 3.6

This is the message I get when I try to use “repair” with mongodb 4.2: mongodb_mongo.1.vhmuaw0jsyfb@smtp001.yvd.grp | 2022-07-27T09:58:29.028+0000 I - Pastebin.com
(previous versions just shut down without repairing anything)

Is there any chance that this will eventually succeed?
