Description SATHEESARAN 2019-06-13 17:36:03 UTC

Description of problem:
------------------------
During RHHI-V deployment, all the devices are blacklisted.
This decision should be made by the admin, as the setup may or may not have multipath disks.

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
RHHI-V 1.6
gluster-ansible-roles-1.0.4-4

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

Steps to Reproduce:
-------------------
1. Complete gluster deployment procedure of RHHI-V deployment

Actual results:
---------------
1. /etc/multipath.conf file is generated with 'vdsm-tool configure --force'
2. /etc/multipath.conf file is edited to blacklist all the devices

Expected results:
-----------------
Do not perform any of the multipath configuration to blacklist the disks

The dependent bug is already ON_QA, moving this bug to ON_QA

Comment 4 SATHEESARAN 2019-06-26 01:33:48 UTC

Tested with RHVH 4.3.5 + RHEL 7.7 + RHGS 3.4.4 ( interim build - glusterfs-6.0-6 ) with ansible 2.8.1-1
with:
gluster-ansible-features-1.0.5-2.el7rhgs.noarch
gluster-ansible-roles-1.0.5-2.el7rhgs.noarch
gluster-ansible-infra-1.0.4-3.el7rhgs.noarch

Gluster configuration is done with the following modifications:
1. Glusterfs systemd slice configuration removed in favor of configuring the same while adding the host to RHVM managed cluster
2. Configuration of multipath removed: no blacklisting of devices
3. Package installation step is removed, as RHVH has all the packages available

Comment 5 SATHEESARAN 2019-06-26 01:38:03 UTC

doc_text is required for this bug, as this new changes differ from the previously known behavior
"Multipath is no longer configured to blacklist all the local devices.
Its left to the admin to provide multipath WWID during cockpit deployment, in case mpath is configured in the setup"

@Sachi, could you provide doc_text for this bug for the doc_team to add it to 'Release Notes'
