After Mongodump, calling MongoRestore hangs
We are trying to do a simple MongoDump on a relatively small DB.
our steps are simple:
export
drop exisiting DB from target machine
import on target machine
The MongoDump executes perfectly.
mongodump --out=/root/mongo-prod
The same goes for the DB drop:
mongo db_name --eval "db.dropDatabase()"
On the other hand, After calling mongoRestore
mongorestore --stopOnError --drop --db db_name /root/mongo-prod-{{ build }}/db_name/
The import process starts, and hangs on 3 specific collections with the following error repeating:
no collection options to restore
restoring db_name.Collection4 from file /root/mongo-prod-31/db_name/Collection4.bson
file /root/mongo-prod-31/db_name/Collection4.bson is 56625 bytes

******* This loops infinitely *******
p.s adding --repair to the mongodump command, creates a different error on mongorestore:
Failed: restore error: db_name.Collection1: error restoring from /root/mongo-prod-33/db_name/Collection1.bson: insertion error: E11000 duplicate key error index: db_name.Collection1.$_id_ dup key: { : ObjectId('5651802de4b0293285f7f508') }
Answer
I just spent an hour with this:
Read from archive
--archive=/backup...
Ignore the archive argument and wait for stdin
--archive /backup
Seems arguments work with either arg value or arg=value, just not archive...
