AFR arbiter volumes:
--------------------------
Arbiter configuration is special type of 3 way replica volume in AFR 
where the 3rd brick holds only the meta-data of the file. It consumes 
less space than  a 3 way replica, provides the same consistency and 
prevents split-brain of files. More about the usage @ 
https://github.com/gluster/glusterfs-specs/blob/master/done/Features/afr-arbiter-volumes.md

Recent enhancements for 3.7.7 include:
-Indicating which bricks are arbiters in the output of `gluster volume 
info` (http://review.gluster.org/#/c/12747/)
-Skipping data-selfheal for arbiter bricks since they are zero byte 
files containing only metadata.(http://review.gluster.org/12778)
-An important bug fix which prevents arbiter bricks from also storing 
the file contents (data) under certain conditions 
(http://review.gluster.org/12479)

Thanks,
Ravi
