问题
I have a script which dumps a mongodb
mongodump --archive=$MONGODB_PATH --host $MONGODB_HOST --port $MONGODB_PORT --username $MONGODB_USER --password $MONGODB_PASS --db $MONGODB_NAME
but when I try to restore it with
mongorestore -d db_name backup/dump
it fails with:
Failed: dump_name: error restoring from backup/dump/dump_name: reading bson input: invalid BSONSize: -2120621459 bytes
I tried --batchSize=100 but it didn't solve the issue for me.
What's going wrong here?
Solution was:
mongorestore --archive=backup/dump
回答1:
When you dump with --archive flag you must restore with --archive flag as well.
