Fixed In Version: glusterfs-3.7.9-1
Doc Type: Bug Fix
Doc Text:
Previously, using the force option with the 'gluster volume start' command succeeded even when server-side quorum was not met. This has been corrected so that force no longer overrides a lack of server-side quorum being met.

Description Byreddy 2016-02-11 09:41:35 EST
Description of problem:
Had a four node cluster and created a Distributed volume using one brick and enabled the server quorum and server-quorum ratio was 90, and stopped glusterd in one of the node to achieve server quorum not met condition based on server quorum ratio set and started the volume, *it's started and bricks are online**

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

How reproducible:
Every time

Steps to Reproduce:
1.Have 4 node cluster (node-1..4)
2.Create a simple distributed volume using one brick
3.Enabled the server quorum 
4.Set the server quorum ration to 90
5.Stop glusterd on one of the node (eg :node-4)
6.Try to start the volume now //will start and bricks will be online

Actual results:
Bricks are online when server quorum not met

Expected results:
Bricks should be in offline when server quorum not met

Comment 13 Atin Mukherjee 2016-02-15 00:46:55 EST
We have a crude workaround here which is as follows:

1. Disable server side quorum by gluster volume reset <volname> cluster.server-quorum-type
2. Stop the volume
3. Turn on server side quorum by gluster volume set <volname> cluster.server-quorum-type server

The fix is now available in rhgs-3.1.3 branch, hence moving the state to Modified.
Comment 22 Byreddy 2016-04-04 03:17:10 EDT
Verified this bug using the build "glusterfs-3.7.9-1"

Repeated the reproducing steps mentioned in description section of bug, Fix is working properly, volume start is not happening when "server side quorum not met"

Moving to verified state based on above info.

This bug doesn't need a doc text since its a regression. Apologies for this effort waste.

Also if you see any bugs which Gaurav has worked on, raise needinfo on me instead of Satish :)
