Anda dapat menambahkan berikut ke file konfigurasi yang disediakan saat menjalankan mongod --config mongod.conf
Untuk MongoDB 3.x (versi terbaru)
storage:
mmapv1:
smallFiles: true
Untuk versi 2.6+
storage:
smallFiles: true
Untuk versi 2.4 dan lebih sedikit
smallfiles = true
Kemudian jalankan mongod untuk menerima file konfigurasi Anda (di sini diasumsikan bahwa lokasi konfigurasi adalah /etc/mongodb.conf ):
mongod -f /etc/mongodb.conf
Dokumentasi untuk file kecil parameter:
Set to true to modify MongoDB to use a smaller default data file size.
Specifically, smallfiles reduces the initial size for data files and
limits them to 512 megabytes. The smallfiles setting also reduces the
size of each journal files from 1 gigabyte to 128 megabytes.
Mulai mongod misalnya menggunakan perintah berikut
mongod --dbpath /data/db --smallfiles
Saya mengikuti panduan resmi di http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
Setelah menggunakan
$sudo service mongod start
Saya pergi untuk memverifikasi apakah MongoDB telah berhasil dimulai dengan meninjau log ini:
/var/log/mongodb/mongod.log
Inilah masalah yang saya temukan:
2014-11-11T12:54:05.808-0500 [initandlisten] ERROR: Insufficient free space for journal files

Solusi:
Di akhir file /etc/mongod.conf saya menambahkan baris ini:
smallfiles = true
Setelah itu, saya memulai kembali layanan mongod:
$sudo service mongod restart
Kemudian ketika saya meninjau log, saya menyadari bahwa semuanya sempurna, dan masalahnya telah diperbaiki:
