[Gluster-users] add-brick to replicated setup

hi Patrick,
     Because the Volume is created with replica type with 2 bricks per replica, you can only add bricks only in multiples of two.

Hi List,

I am running gluster 3.1.2 on a three node gentoo based cluster.

I have set up a two brick replicated setup.

#gluster volume info repstore1

Volume Name: repstore1
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp
Brick1: gluster1:/iscsi/1/data
Brick2: gluster3:/data/gluster3.data

I can not add a new brick to it though,

# gluster volume add-brick repstore1 gluster3:/iscsi/2/data
Incorrect number of bricks supplied 1 for type REPLICATE with count 2

is this incorrect syntax or is this just not possible right now?
