Major - P3 Hello there, can someone help me? I've mounted my data volume into a docker container running a mongod and accidentally stopped the execution with CTRL-C. After that I could not restart my local mongod using the same data directory. I saw in some issues e.g here SERVER-31196(https://jira.mongodb.org/browse/SERVER-31196)) that the problem may be resolved by replacing some WiredTiger files. So I did. But unfortunately that didn't work out.
Could you tell me:
- is a recovery possible somehow? Even now that I have replaced my original WiredTiger.wt and WiredTiger.turtle files?
- what information do you need from me then?
Here is the stacktrace of my initial try using the `--repair` statement.
Thank you in advance. Matthaeus
