Gluster users - Jun 2015 - Replicated with bricks of different sizes

We are/were running a simple 1x2 replica volume and have had a major 
failure on one of our gluster servers. We want to create a new replica, 
at least for the time being, but don't have another available server 
with sufficient drive space. Working on the assumption that we will not 
increase the disk usage, and will therefore not get anywhere near the 
capacity of the smaller server's drives, is it safe to create a replica 
using mismatched brick sizes? Will gluster even allow that?

regards,
John

I did bit of testing of this some time ago. Not with the lastest Gluster
mind you... You can have different size bricks in a volume but you
should always have the same size bricks in a replica.

You say that there's enough space and no space will be consumed after
etc and in theory this could work. But I wouldn't certainly recommend
this kind of setup.
