Description SATHEESARAN 2020-03-10 13:32:37 UTC 
Description of problem:
-----------------------
As I look at the code, it tries to blacklist the disks before turning on NBDE.
We should really look for inputs from user, whether they have multipath in the configuration. Only in the absence of multipath configuration, all the required devices should be blacklisted

Version-Release number of selected component (if applicable):
--------------------------------------------------------------
gluster-ansible-infra-1.0.4-5.el8rhgs.noarch.rpm

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

Actual results:
----------------
All the devices are blacklisted

Expected results:
-----------------
Devices should be blacklisted based on the requriements
Default behavior should be blacklisting the required devices.

--- Additional comment from SATHEESARAN on 2020-03-10 12:37:53 UTC ---

Also the procedure to blacklist is by adding the blacklist block to the file created under /etc/multipath/conf.d/<file.conf>
Comment 2 SATHEESARAN 2020-03-21 10:59:23 UTC 
Tested with gluster-ansible-infra-1.0.4-6
