Description Nag Pavan Chilakam 2018-01-02 14:53:36 UTC
Description of problem:
======================
when verifying bz#1526373 - Brick Multiplexing: Gluster volume start force complains with command "Error : Request timed out" when there are multiple volumes 

heal info shows the brick as transport end point error, ie still not online.
even when the brick is online.
this obviously leads to more entries pending heals as more IOs are pumped in

the chance of hitting this problem is about 50%

Version-Release number of selected component (if applicable):
===========
glusterfs-server-3.8.4-52.3.el7rhgs.x86_64

How reproducible:
=================
2/4

Steps to Reproduce:

1. create a brick mux setup
2. create about 60 ecvols all 1x(4+2)
3. start the volumes
4. pump IOs to the base volume and another volume(i created an extra ecvol for this)
5.now kill a brick say b1
6. use volume force start of any volume(some vol in higher ascending order say vol15 or vol20 ...and not the base volume)
7. now start other volumes ie the mounted vols using vol force 




Actual results:
=========
healinfo still sees brick down
shd fails to start on one of the vols (raised a seperate BZ#1530217 - Brick multiplexing: glustershd fails to start on a volume force start after a brick is down)

logs of  BZ#1530217 can be used
