My server broke down and all I had is copy of database files in /data/db. No proper mongodump, only files.
After restoring my VPS from snapshot, I tried to run mongo, get error (see in attachment)
Answering to your question:
1. Which version of MongoDB was the original mongod using?
Original was 3.2.4. However, I already updated to 3.4.3 with hope that this will be fixed.
2. What method do you use to create backups?
That is the problem, that I didnt have mongodumps. Only *.wt files.
3. Have you ever manipulated (copied or moved) the underlying database files? If so, was the mongod running?
No I didnt touch files. After restoring from snapshot, server state was same as before server fault.
Please find all screenshots and WiredTiger.wt/ WiredTiger.turtle files.
Is it any chance to restore from unclean shutdown only with *.wt files.?
