As far as I know you can add bricks to a replica volume just fine but
you need to add as many as your count was when you created the volume.
If you created your volume with 'count 3' as it sounds you did then you
need to add three bricks at once that will replicate with each other (or
6, 9, 12...). If you want to change your count then you have to stop,
delete, and re-create the volume. There is a way to do this with
downtime but without losing data.
The "can't change replica count" issue may have changed in 3.3 but I
don't run non-GA releases so I don't know. Also you didn't say what
version you are running nor provided the output of 'gluster volume info'.

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
