Description Byreddy 2017-02-09 06:49:11 UTC 
Description of problem:
=======================
modification done to the volume when some cluster are down are not synced once offline nodes comes up.



Version-Release number of selected component (if applicable):
==============================================================
glusterfs-3.8.4-14

How reproducible:
=================
Always


Steps to Reproduce:
====================
1. Have 3 nodes cluster
2. Create and start a Distributed volume using 3 bricks (pick one from each node)
3. stop glusterd on two nodes (say n2 and n3 )
4. change these volume options from default to 
performance.readdir-ahead from on to off
cluster.server-quorum-ratio from default value to 30
5. Now start glusterd on n2 and n3 nodes
6. check the volume info on both nodes and check modified volume options are synced.

Actual results:
===============
Modified volume options not synced once offline nodes comes up.


Expected results:
=================
sync should happen once nodes comes up.

Comment 4 Atin Mukherjee 2017-02-09 07:33:31 UTC 
upstream patch : https://review.gluster.org/16574
Comment 5 Byreddy 2017-02-09 08:24:23 UTC 
This issue is not there in 3.1.3 GA build.
Added Regression keyword.
Comment 7 Atin Mukherjee 2017-02-09 08:41:34 UTC 
http://review.gluster.org/14876 (came as part of rebase to 3.8.4) has caused this regression.
Comment 8 Atin Mukherjee 2017-02-12 15:51:47 UTC 
downstream patch : https://code.engineering.redhat.com/gerrit/#/c/97503/
Comment 10 Prasad Desala 2017-02-21 05:45:42 UTC 
Verified this BZ on glusterfs version 3.8.4-15.el7rhgs.x86_64.

Followed the below steps:
1) Created and started a Distributed volume using 3 bricks (picked one from each node)
2) stopped glusterd on two nodes (n2 and n3 )
3) From node1, changed the below volume options from default
performance.readdir-ahead from on to off
cluster.server-quorum-ratio from default value to 30
4) Now, started glusterd on n2 and n3 nodes
5) checked the volume info on all the 3 nodes and the above modified volume options are in sync across all the 3 nodes.

Hence, moving this BZ to verified.
