Mongos not starting. "unknown option nojournal"

[Douglas Garstang]

All,

 I am trying to deploy mongo 2.6.1. I'm having a problem starting mongos.

My /etc/configdb.conf file looks like this:

bind_ip = 0.0.0.0
configdb = cfg01.prod.foobar.com:27017,cfg02.prod.foobar.com:27017,cfg03.prod.foobar.com:27017
fork = true
logappend = true
logpath = /var/log/mongodb/mongodb.log
nojournal = false
port = 27017
rest = false
smallfiles = false

I understand that in mongo 2.6, the config file format was moved to YAML. However, the docs at http://docs.mongodb.org/manual/reference/configuration-options/ say that the format is backwards compatible.

"Changed in version 2.6: MongoDB introduces a YAML-based configuration file format. The 2.4 configuration file format remains for backward compatibility."

However, when I start mongos, I see this:

[root@router01 init.d]# service mongos start
Starting mongos: Error parsing INI config file: unknown option nojournal

So, I replaced the config file at /etc/mongodb.conf with the example at one at http://docs.mongodb.org/manual/reference/configuration-options/, ie:

systemLog:
  destination: file
  path: "/var/log/mongodb/mongodb.log"
  quiet: true
  logAppend: true
storage:
  journal:
    enabled: true
processManagement:
  fork: true
net:
  bindIp: 127.0.0.1
  port: 27017

However, now, when I start mongos, I get this:

[root@router01 init.d]# mongos -f /etc/mongodb.conf 
Unrecognized option: storage.journal.enabled

Needless to say I'm a little confused. Mongo version is:

root@router01 init.d]# rpm -qa | grep mongo
mongodb-org-tools-2.6.1-2.x86_64
mongodb-org-server-2.6.1-2.x86_64
mongodb-org-mongos-2.6.1-2.x86_64
mongodb-org-shell-2.6.1-2.x86_64
mongodb-org-2.6.1-2.x86_64


What am I doing wrong? Why won't mongos take any of the config options in /etc/mongodb.comf?
The mongod process starts fine.

Since mongos does not having any files of its own (and no directory
dbpath) the journaling options don't make sense with it.

Journaling only applies with mongod processes since they store data.
