I downloaded mongodb-linux-x86_64-3.2.8.gz (not enterprise) to set up MongoDB 3.2 replica on Red Het Enterprise Linux 6.6. I got "Unrecognized option: Storage.directoryPerDB" error when I started the DB.

$ numactl --interleave=all /opt/mongo-3.2.8/bin/mongod -f /etc/mongod.conf
Unrecognized option: Storage.directoryPerDB

$ cat /etc/mongod.conf
storage:
dbPath: "/var/data/mongodb"
directoryPerDB: true
journal:
enabled: true
systemLog:
destination: file
path: "/var/log/mongodb/mongod.log"
...

Please advise.

Thanks,
Ed
