Re: [Gluster-devel] [PATCH] Enable replica 1 mirror creation for mirrored volumes

[Craig Carl, Gluster]

Avati - 
   This type of functionality is incredibly useful from an IT operations POV, 
my thinking is it would make migrating from a distribute only to a 
distribute-replica volume easier.

Joe, 
Can you shed some more light on the use case? What purpose is the replicate 
translator serving without the second server? In what way is this more 
beneficial than loading the replicate translator only when the second server is 
introduced to the system?

This patch to the cli enables a very simple replica 1 mirror creation (similar 
to the "missing" attribute for mdadm RAID1 creation). 

It will likely need additional supporting work in add-brick so that incomplete 
mirrors are assembled correctly for distributed-replicated cases. 

Building/Assembling an incomplete mirror is an important capability needed for 
a number of use cases.
