Mongodb data corruption

Hi,

I am using mongodb 4.0.26 and 3 node replicaset and nearly 500GB data, it has. Sometimes, especially one node getting crash. Data corruption occurs.

İnitial sync is not a complete solution. Because even if ı do initial sync by deleting data file, after one or two months later it getting crash again.

And also my disk is SSD.

When I check the log file, ı can see checksum errors. What is the reason and permanent solution.


This is likely a storage issue. Start with a healthcheck on the ssd.
