After a system crash, MongoDB (4.0.6) refuses to start because of corrupted data.
Mongod --repair does not fix it:
WT_CURSOR.search_near: read checksum error for 24576B block at offset 57344: block header checksum of 3933356853 doesn’t match expected checksum
(full log: https://controlc.com/72632df7)
I try to repair with more recent tool with more effect.
I’m not able to execute a mongodump because Mongod refuses to start.
How can I restore collection?
How to retrieve data from collection files (for instance collection-101–1569900909144710.wt)?
What is recommended for MongoDB resilience: backup, distribution?
Thanks by advance.
