Создал папку /var/lib/mongoWT (права, владелец все как у папки с файлами стараджа mmapv1)
Изменяю секцию сторадж в конфиге MongoDB:
# Where and how to store data.
storage:
dbPath: /var/lib/mongoWT
journal:
enabled: true
engine: wiredTiger
# mmapv1:

Перезапускаю сервис mongod:
[root@AdSpend ~]# systemctl restart mongod
Job for mongod.service failed. See 'systemctl status mongod.service' and 'journalctl -xn' for details.
