Description Adrian Gruntkowski 2015-11-19 10:28:28 UTC 
Description of problem:

Currently there's no clear indication of volume being in an arbiter setup in the "gluster volume info" output. There's a change addressing that in 

http://review.gluster.com/#/c/12479/

but it still is a bit cryptic.

Version-Release number of selected component (if applicable):

arbiter in GlusterFS 3.7.6 with a patch applied from http://review.gluster.com/#/c/12479/

How reproducible:

Issue "gluster volume info test-volume" where "test-volume" is a volume with an arbiter brick.


Actual results:

Volume Name: system_mail1
Type: Replicate
Volume ID: 7a49e1a2-01d3-4fe7-ac61-173757396250
Status: Started
Number of Bricks: 1 x (2 + 1) = 3
Transport-type: tcp
Bricks:
Brick1: cluster-rep:/GFS/system/mail1
Brick2: mail-rep:/GFS/system/mail1
Brick3: web-rep:/GFS/system/mail1
Options Reconfigured:

Expected results:

Volume Name: system_mail1
Type: Replicate
Volume ID: 7a49e1a2-01d3-4fe7-ac61-173757396250
Status: Started
Number of Bricks: 1 x (2 + 1) = 3
