I can't start my mongo instance after restoring a snapshot. Journaling is enabled but I guess some file are corrupted.
it looks a lot like Is there any way to repaire WiredTiger.wt and WiredTiger.turtle to discard any pending changes ?
I can not find anything in the documentation.
Thank you

To prevent this type of problem in the future please take note of the following guidelines to help mitigate any issues related to unreliable storage layers or server failures:

I've attached the files after a repair attempt. Would you please extract these files, substitute them for the current ones in your $dbpath, and let us know if it resolves the issue? Thanks,
