I am using MongoDB v2.6.10
This is my configuration file, /etc/mongodb.conf
# mongodb.conf
# Where to store the data.
dbpath=/var/lib/mongodb
#where to log
logpath=/var/log/mongodb/mongodb.log
logappend=true
bind_ip = 127.0.0.1
#port = 27017
# Enable journaling, http://www.mongodb.org/display/DOCS/Journaling
journal=true
When I am starting the MongoDB server,
sudo service mongodb restart
This error is showing,
exception in initAndListen: 28574 Cannot start server. Detected data files in /var/lib/mongodb created by storage engine 'wiredTiger'. The configured storage engine is 'mmapv1'., terminating
I am not sure why it is taking wiredTiger
engine, when I have not configured it anywhere.
