mongodb configration issue

Hi, Am editing configuration of running mongodb in 'amazon ubuntu instance'(have more than 30 GB data), and I attached some volumes I for data, log, and joural

I followed mongodb-ec2

• formated the volumes


• mount /data , /log and /journal


• stop mongodb


• edit /etc/mongodb.conf

mongodb.conf

dbpath=/data

• copy all files from old dir to new mount volumes.


• start mongodb For testing I run a python script,

from pymongo import MongoClient

db = MongoClient().my_testdb

I got the error message, ymongo.errors.ConnectionFailure: could not connect to localhost:27017: [Errno 111] Connection refused.

So remove the lock from the /data/mongod.lock.

and run sudo mongod --repair The following error I got. ..........

ERROR: dbpath (/data/db/) does not exist ........

My question is, even though I configured dbpath=/data, why it try to look for the path /data/db? how can I resolve it?
