I copy the mongo data directory to another directory, then restart mongo and use the new data directory, it can start normally, but it will exit unexpectedly at an uncertain time
There is about 400G of data in this database, and there is no copy or even backup, which is embarrassing.
This is the current version of mongodb.
root@iZ8vbaz9bzczwu67s939mfZ:~# mongod --version db version v3.0.14 git version: 08352afcca24bfc145240a0fac9d28b978ab77f3
I don't know how to start now, I hope to get your help.
Below is the log I saw
