I have 2 disk devices for the database of MongoDB like this

$ df
Filesystem           Mount Position
/dev/xxx1            /
/dev/xxx2            /work

If I make the database and the collection, is it impossible like below?
And on each case how do I write the command.(for example createCollection)

１．To allocate each collection to each disk device on same database

database user
collecttion  data1 --->  /dev/xxx1
collecttion  data2 --->  /dev/xxx2

２．To allocate each collection and each databases to each disk device

database user1
collecttion  data1 --->  /dev/xxx1
database user2
collecttion  data2 --->  /dev/xxx2

Hi Gowest,

MongoDB stores all its data under one folder which is controlled by the
DBPath variable.

http://www.mongodb.org/display/DOCS/Starting+and+Stopping+Mongo#Start...

There are no methods within mongo to direct the output for different
databases to different locations.

Hope that clears things up,

David

Hi David. Thanks a lot !!

>>There are no methods within mongo to direct the output for different

I got it.

But that link is very available.

I'll make effort to decrease the data amount, or re-build the database on a
larger space than current.

You can specify the directoryperdb option to have each database in a
different directory, under dbpath. In this way you can store different
databases on difference devices using symlinks or mount points.

http://www.mongodb.org/display/DOCS/--directoryperdb

This allows you to do number 2.

Hi, Scott. Thanks a lot for an available massage.

I think it might be the way to do waht I want.

But, It is impposible to use the option when I create  the database.

Best Regards.

It is a mode you start the server in. You can create the db
directories and move the files over if you started without it. Just
create the directories with the same name as the database, and put all
the database files in there with that name.

Hi, Scott.

Its been a while.

Now, I need your addvise.

I made 2 databases under same directory like this,
(under /var/db/mongo)

db1 col1.0 col1.1 col1.ns
db2 col2.0 col2.1 col2.ns

I want to move db2 database to other directory(/home/mongo).

So, I do the mongod command like this

/opt/mongodb/bin/mongod --dbpath /home/mongo/col2.0 --directoryperdb

But it didn't work well.

How do I write the command?

Hi Gowest

I think you should make directory "db2" in "/home/mongo" . And you could
start your database by command: /opt/mongodb/bin/mongod --dbpath
/home/mongo/db2 --directoryperdb

Thanks.

Hi Tom. Thank you for your reply.

At that example, db1 and db2 are not directories but databases.

If I make new database with dedault sessing by createCollection command,
New database is build under a default directory.

Can I make db2 under another directoty ?

Best Regard.
