Gluster users - Jan 2012 - Howto add bricks to a replicated Volume

Hi,

I am running a three Node replicated Volume and need to add more
Bricks. What I've read so far this that this is not really possible so
the question is how it should/can be done?
Can I create a replicated Volume with 10000 Bricks where 9997 are
missing? Is there a way that I didn't find so far?
The Gluster Volume is used to store images for a Webshop in the Amazon
Cloud and I can't really stop the Volume and recreate it with XX
Bricks every time a new Server is added.

Thanks a lot,
Ben

Ben,

You can add bricks to the volume using 'gluster volume add-brick'
command.

And which version of glusterfs are you using? If it's 3.2.x version, 
then you can't change the replica count once the volume is created. That 
means your replicated volume will become distributed-replicated volume 
after add-brick. And you can only add bricks in multiples of replica count.
However, In 3.3  branch there is provision to change the replica count 
after volume creation.

Best Regards,
Vishwanath
