ubuntu - MongoDB Failed: can't create ActualPath object from path dump: stat dump: no such file or directory -


i have bunch of mongo databases need restore. used mongodump backup directories, include collections inside of them. this:

|- mydir |-- db1 |--- collection1 |--- collections2 |-- db2 |--- collection1 |--- collections2

i cd mydir , mongorestore , following error:

2016-07-25t10:41:12.378-0400    using default 'dump' directory 2016-07-25t10:41:12.378-0400    failed: can't create actualpath object path dump: stat dump: no such file or directory

then try restore specific database this: mongorestore db2 , following errors:

2016-07-25t10:47:04.413-0400    building list of dbs , collections restore db2 dir 2016-07-25t10:47:04.413-0400    don't know file "db2/collection1.bson", skipping... 2016-07-25t10:47:04.413-0400    don't know file "db2/collection1.metadata.json", skipping..."db2/collection2.bson", skipping... 2016-07-25t10:47:04.413-0400    don't know file "db2/collection2.metadata.json", skipping... 2016-07-25t10:47:04.414-0400    done

no matter or try, alternate between these 2 errors. , it's same of databases use.

i tried using --db flag, -d parameter, setting dump path third argument (mongorestore --db [db] [dump_path]). found around stackoverflow. nothing.

i'm stuck on , have no idea how proceed.

edit

os: ubuntu 14.04

installed mongodb following guide:

https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

mongorestore no dump_path positional argument expecting there folder named dump in current working directory. if folder dump not exist, "can't create actualpath..." error.

so if not have folder named dump, need pass positional argument. parent directory of mydir run:

mongorestore mydir

if want use --db option need specify dump path way down directory contains .bson files database or specific .bson file.

so example restore collections db1:

mongorestore --db db1 ./db1

or restore collection1:

mongorestore --db db1 ./db1/collection1.bson
