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@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
The brick directory will have some xattrs while being part of the volume. So you will have to remove the xattrs from the directory before adding the brick to the volume again. You can simply delete the directory and re-create it again.
[root@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
Since you have replica 2 volume, you should add/remove at least 2 bricks at a time. You can try the following (after you delete and re-create gwgfs02:/data/brick1/vol01)
gluster volume add-brick vol01 gwgfs02:/data/brick1/vol01 gwgfs03:/data/brick1/vol01
