[Gluster-Maintainers] [Gluster-devel] Master branch lock down status

[Ashish Pandey]

I think the problem with this failure is the same which Shyam suspected for other EC failure. 
Connection to bricks are not being setup after killing bricks and starting volume using force. 

./tests/basic/ec/ec-1468261.t

---------------------------- 
When I see the glustershd log, I can see that there is an issue while starting the volume by force to starte the killed bricks. 
The bricks are not getting connected. 
I am seeing following logs in glustershd----

[2018-08-06 23:05:58.204494]:++++++++++ G_LOG:./tests/basic/ec/ec-1468261.t: TEST: 83 ^0$ get_pending_heal_count patchy ++++++++++ 
There are many more such logs in this duration 
============================ 
Time at which test at line no 80 started - 
[2018-08-06 23:05:38.652297]:++++++++++ G_LOG:./tests/basic/ec/ec-1468261.t: TEST: 80 6 ec_child_up_count patchy 0 ++++++++++ 
Time at which next test started to get pending heal count - 
[2018-08-06 23:05:58.204494]:++++++++++ G_LOG:./tests/basic/ec/ec-1468261.t: TEST: 83 ^0$ get_pending_heal_count patchy ++++++++++ 
Time gap is 20 second which is exactly the time for which we wait for all the connection to come up in our tests. 
78 #Bring up the down bricks 
79 TEST $CLI volume start $V0 force 
80 EXPECT_WITHIN $CHILD_UP_TIMEOUT "6" ec_child_up_count $V0 0 
81 
82 #Wait for heal to complete 
83 EXPECT_WITHIN $HEAL_TIMEOUT "^0$" get_pending_heal_count $V0 
In this time, 20 seconds, bricks did not come up. That's why test on line no 80 failed. As bricks did not come UP, heal did not happen and that lead to failure of test at line no 83.
