[Gluster-users] Problem adding brick to an existing volume

Hi,

It is a distribute-replica type of volume with replica count 2. Hence 
whenever you add bricks you have to add bricks in multiple of 2. 
Hence the error - Incorrect number of bricks supplied 1 with count 2.

You can just add bricks in multiple of 2 instead of changing the replica count. Also in the above
command you have given the replica count as 3 yet supplied just one brick, hence the command fails.
