My mongo slave is dead because it stopped unexpectedly due to not enough space and It wont start due to
mongodb.service: Main process exited, code=exited, status=14/n/a
I tried to fix the error with following suggestions:
https://askubuntu.com/questions/823288/mongodb-loads-but-breaks-returning-status-14
but it lead to next error code:
mongodb.service: Main process exited, code=exited, status=100/n/a
which I tried to fix with following
https://dba.stackexchange.com/questions/220411/sudo-service-mongod-start-returns-error-100
this it it log output
2021-05-01T18:25:30.987+0000 I - [initandlisten] Fatal assertion 28579 UnsupportedFormat: Unable to find metadata for table:index-3-848131710157586571 Index: {name: _id_, ns: local.me} - version too new for this mongod. See http://dochub.mongodb.org/core/3.4-index-downgrade for detailed instructions on how to handle this error. at src/mongo/db/storage/wiredtiger/wiredtiger_index.cpp 241
The command sudo service mongodb start wont work because the status command shows that the service is dead.
I figured out that it would be easier to resync the data from scratch. I found the documentation
https://docs.mongodb.com/manual/tutorial/resync-replica-set-member/#resync-a-member-of-a-replica-set
but I am not fully aware what commands run to execute this operation.
My dbPath = "/mnt/mongo/mongodb", MongoDB shell version v3.4.14, and my database has about 2.5T. Could you give my some guidance how to execute initial sync mongo replica?
From my understanding i should
sudo rm -r /mnt/mongo/mongodb/*sudo service mongodb start- After some time everything should get back to normal(?)
Correct me if I am wrong...
