[Gluster-users] Add brick question.

[何亦军]

Hi Guys,

     I have two servers in my pool , I plan add new server to that pool.
     My volume info below:

    Volume Name: vol01
Type: Distributed-Replicate
Volume ID: 0bcd8d7c-b48a-4408-b7b8-56d4b5f8a97c
Status: Started
Number of Bricks: 2 x 2 = 4
Transport-type: tcp
Bricks:
Brick1: gwgfs01:/data/brick1/vol01
Brick2: gwgfs02:/data/brick1/vol01
Brick3: gwgfs01:/data/brick2/vol01
Brick4: gwgfs02:/data/brick2/vol01

I plan to form a combination:

Brick1: gwgfs01:/data/brick1/vol01
Brick2: gwgfs03:/data/brick2/vol01
Brick3: gwgfs01:/data/brick2/vol01
Brick4: gwgfs02:/data/brick2/vol01
Brick5: gwgfs02:/data/brick1/vol01
Brick6: gwgfs03:/data/brick1/vol01

My processing steps：

1.       gluster peer probe gwgfs03

2.       gluster volume replace-brick vol01 gwgfs02:/data/brick1/vol01  gwgfs03:/data/brick2/vol01 status

3.       After replace completed, do: gluster volume rebalance vol01 start

And  finally  I try to add brick meet problem:
[root at gwgfs03 vol01]# gluster volume add-brick vol01 gwgfs02:/data/brick1/vol01  gwgfs03:/data/brick1/vol01
volume add-brick: failed: /data/brick1/vol01 is already part of a volume

[root at gwgfs03 vol01]# gluster volume remove-brick vol01 gwgfs02:/data/brick1/vol01 start
volume remove-brick start: failed: Remove brick incorrect brick count of 1 for replica 2

Current , my volume info below:    What can I do now? Help?

[root at gwgfs03 vol01]# gluster volume info
