[Gluster-users] Can I remove a brick for dispersed volume on 3.9?
Hi, I am new to glusterFS and now I am trying it with the proxmox VE under lab situation. I have 5 nodes on proxmox VE and made a dispersed volume of 1 x (4 + 1) = 5. however, the node02 has failed to work now. so i plan to reinstall proxmox VE on node02 so i need to remove the brick on node02 but i failed with this message: gluster> volume remove-brick DispersedVol node02:/gluster/node02/brick01 force Removing brick(s) can result in data loss. Do you want to Continue? (y/n) y volume remove-brick commit force: failed: Remove brick incorrect brick count of 1 for disperse 5 is that possible to remove a brick from the dispersed volume in this kind of circumstance? here is some information of my volume: root at node04:~# gluster gluster> peer status Number of Peers: 4 Hostname: node02 State: Peer in Cluster (Disconnected) Hostname: node05 State: Peer in Cluster (Connected) Hostname: node03 State: Peer in Cluster (Connected) Hostname: node01 State: Peer in Cluster (Connected) gluster> volume info Volume Name: DispersedVol Type: Disperse Status: Started Snapshot Count: 0 Number of Bricks: 1 x (4 + 1) = 5 Transport-type: tcp Bricks: Brick1: node01:/gluster/node01/brick01 Brick2: node02:/gluster/node02/brick01 Brick3: node03:/gluster/node03/brick01 Brick4: node04:/gluster/node04/brick01 Brick5: node05:/gluster/node05/brick01 Options Reconfigured: nfs.disable: on performance.readdir-ahead: on transport.address-family: inet Anybody can help?

I am not an expert, but I think bricks could not be removed on dispersed volume. Maybe ?volume replace-brick? could be more accurate in this situation ?> On 10 Dec 2016, at 12:13, Zhang Hang <hangzzzzz at qq.com> wrote: > > Hi, > I am new to glusterFS and now I am trying it with the proxmox VE under lab situation.
