[Gluster-users] Help! Can't replace brick.

[Tao Lin]

Hello, glusterfs experts:
    I'v been using glusterfs-3.2.6 for moths, and it works fine.Now i'm
facing a problem of disk(brick) full.For some resons, I have to expand
space using replace current bricks to new bricks instead of add new bricks.

It seemed okay when i  used this command :
gluster volume replace-brick volume1 10.67.15.35:/media/data1/brick1
10.67.15.27:/data1/brick1 start
When i tried to use the command:
gluster volume replace-brick volume1 10.67.15.35:/media/data1/store4appstore1
10.67.15.27:/data1/store4appstore1 status
however, glusterfs reported this: replace-brick status unknown, and
glusterd's log said:

I've also found a strange problem,  a node had probed itself.

[root at yq33 ~]# gluster peer status
Number of Peers: 2

Hostname: 10.67.15.33                                        <<<=== it
shows itself.
Uuid: c213f7ab-18c1-40e1-85c8-dd7ae97fad03
State: Peer in Cluster (Connected)

Hostname: 10.67.15.35
Uuid: 98949cd6-2b61-4ba8-8b67-76d8b58d4ce8
State: Peer in Cluster (Connected)

But on another node, it shows correctly.

[root at yq35 ~]# gluster peer status
Number of Peers: 1

Hostname: 10.67.15.33
Uuid: c213f7ab-18c1-40e1-85c8-dd7ae97fad03
State: Accepted peer request (Connected)

Now I'm really stuck in this big trouble, can anyone help me out, please?

Regards.
