            Bug ID: 1539657
           Summary: Georeplication tests intermittently fail
           Product: GlusterFS
           Version: 4.0
         Component: geo-replication
          Assignee: bugs at gluster.org
          Reporter: nigelb at redhat.com

        Depends On: 1537602



+++ This bug was initially created as a clone of Bug #1537602 +++

The tests fail due to a possible configuration issue. Shyam and I debugged it
down to that. Going to disable the test to unblock all the other reviews.

REVIEW: https://review.gluster.org/19301 (tests: Disable geo-rep tests) posted
(#1) for review on master by Nigel Babu

The test fails in the following runs:

https://build.gluster.org/job/centos6-regression/8602/console
https://build.gluster.org/job/centos6-regression/8604/console
https://build.gluster.org/job/centos6-regression/8607/console
https://build.gluster.org/job/centos6-regression/8608/console
https://build.gluster.org/job/centos6-regression/8612/console

Failure is almost always when checking for which nodes are in "Active" and
"Passive" states, 

06:58:02 not ok 22 Got "1" instead of "2", LINENUM:83
06:58:02 FAILED COMMAND: 2 check_status_num_rows Passive
AND/OR
06:58:02 not ok 37 Got "1" instead of "2", LINENUM:102
06:58:02 FAILED COMMAND: 2 check_status_num_rows Passive

On checking slave25 and rerunning this test (from a fresh clone of the sources
etc.) post step in line 83 it is noted that the command output looks as
follows,


[root at slave25 ~]# gluster volume geo-replication master 127.0.0.1::slave status

The above never recovers, and so is not a timing issue per-se.

Can someone from the geo-rep team take a look at the logs from those runs to
determine what is going wrong and why is the status "Faulty" or Initializing"
as that seem to be th estart of the test failure.
