<div class="moz-cite-prefix">bricks are not peers and vica versa.<br>
<br>
Your peers are the nodes, bricks are the disks on the nodes. When
you remove a bricks from the cluster you don't remove the peer.<br>
<br>
# gluster peer detach 192.168.0.124:/data/brick1<br>
<br>
Incorrect syntax, the command is for removing the peer, not the
brick. It should be:<br>
<br>
# gluster peer detach 192.168.0.124<br>
<br>

<div>It doesn't show that 192.168.0.124 is in the volume but it
is in the cluster. Here is why:</div>
<div><br>
</div>
<div>When I try to add it back to peer list it doesn't do
anything. Because it says that it is already in a peer list:</div>
<div>
<div><br>
</div>
<div># gluster peer probe 192.168.0.124</div>
<div>peer probe: success. Host 192.168.0.124 port 24007
already in peer list</div>
</div>
<div><br>
</div>
<div>OK. I go to the machine 192.168.0.124 and try to show a
peer list:</div>
<div>
<div># gluster peer status</div>
<div>Number of Peers: 0</div>
</div>
<div><br>
</div>
<div>OK. I go to the machine 192.168.0.123 and try to show peer
status:</div>
<div>
<div># gluster peer status</div>
<div>Number of Peers: 2</div>
<div><br>
</div>
<div>Hostname: 192.168.0.125</div>
<div>Uuid: a6ed1da8-3027-4400-afed-96429380fdc9</div>
<div>State: Peer in Cluster (Connected)</div>
<div><br>
</div>
<div>Hostname: 192.168.0.124</div>
<div>Uuid: b7d829f3-80d9-4a78-90b8-f018bc758df0</div>
<div>State: Peer Rejected (Connected)</div>
</div>
<div><br>
</div>
<div>As we see machine with ip 192.168.0.123 thinks that
192.168.0.124 is in the cluster. OK lets remove it from the
cluster:</div>
<div>
<div><br>
</div>
<div># gluster peer detach 192.168.0.124:/data/brick1</div>
<div>peer detach: failed: 192.168.0.124:/data/brick1 is not
part of cluster</div>
</div>
<div><br>
</div>
<div>
<div># gluster peer detach 192.168.0.124</div>
<div>peer detach: failed: Brick(s) with the peer 192.168.0.124
exist in cluster</div>
</div>
<div><br>
</div>
<div>Isn't it strange? It is in the cluster and it isn't in the
cluster. I can't neither add machine with IP 192.168.0.124 nor
remove machine with IP 192.168.0.124</div>
<div><br>
</div>
<div>Do you know what is wrong with it?</div>
<div><br>
</div>
