[Gluster-users] add brick fails

[mkey]

Hi,
I am trying to use tried to glusterfs_3.2.0 on ubuntu natty(11.04).
I have 3 servers, and 2 servers are already added to peer by following
command.
> root at natty3:~# gluster peer probe natty3
> root at natty3:~# gluster peer probe natty4

also, I created volume.
> root at natty3:~# gluster volume create test-volume transport tcp
natty3:/opt/gluster/distributed natty3:/opt/gluster/distributed
> root at natty3:~# gluster volume info
> Volume Name: test-volume
> Type: Distribute
> Status: Created
> Number of Bricks: 2
> Transport-type: tcp
> Bricks:
> Brick1: natty4:/opt/gluster/distributed
> Brick2: natty3:/opt/gluster/distributed


but when I tried to add brick, it failed.
> root at natty3:~# gluster peer probe natty2
> root at natty3:~# gluster volume add-brick test-volume
natty2:/opt/gluster/distributed
> Another operation is in progress, please retry after some time

Mounting volume is OK because if I tried to mount test-volume from
natty3 natty4, and created some files, then I can see them from both
hosts. In addition, probing natty2(new server) is OK because "gluster
peer status" lists natty2.

I have no idea how to get over this.
Any helps are appreciated.
