[Gluster-users] replaceing bricks from a cluster with replication

[John G. Heim]

How can I replace machines in a gluster cluster with triple replication? 
I've had crashes and I've replaces single machines before but always 
with one with the same name. Now I need to take machine1, machine2, and 
machine3 out of the cluster and replace it with machineA, machineB, and 
machineC.

Gluster will not let me detach machine1 all by itself. I have to detach
  machine1, machine2, and machine3 all at the same time. But is that 
going to cause data loss?

It seems to me that detaching all 3 machines in a brick on a triple 
replicated cluster would be like removing a single brick from a 
non-replicated cluster. And you can lose data in that case, right?
