Description SATHEESARAN 2016-08-21 17:24:28 UTC 
Description of problem:
-----------------------
Optimizing the gluster volume for virt store from RHV UI, set the network.ping-timeout value to 10 seconds. This value is too less, so that with more VMs, one may see hearbeat exceeded problems. The recommended value for network.ping-timeout is 30 seconds


Version-Release number of selected component (if applicable):
--------------------------------------------------------------
RHV 4.0.2-7


How reproducible:
------------------
Always

Steps to Reproduce:
-------------------
1. Create a gluster replica 3 volume
2. Optimize the volume for virt-store by clicking 'Optimize for virt-store' tab under the 'volumes' tab


Actual results:
---------------
network.ping-timeout value is set to 10 seconds

Expected results:
------------------
network.ping-timeout value should be set to 30 seconds
Comment 1 SATHEESARAN 2016-08-21 17:25:51 UTC 
After optimizing the volume for virt-store from RHV UI, the volume options looks as follows :

[root@ ~]# gluster volume info

Comment 3 Sahina Bose 2016-12-16 06:07:47 UTC 
Is the network.ping-timeout set to 30 seconds in group virt of gluster?

Sahina,

No. Its not the part of the group virt.

I think the value of ping-timeout=10secs is burned (hard-coded) somewhere in the vdsm code
Comment 5 SATHEESARAN 2017-02-08 17:51:58 UTC 
Tested with RHV 4.1 beta1 ( Red Hat Virtualization Manager Version: 4.1.0.3-0.1.el7 )

When the volume optimized for virt-store, the volume option 'network.ping-timeout' was set to 30 seconds now
