Comment 2 SATHEESARAN 2020-03-20 14:44:19 UTC
As per my conjecture, this looks like problem because of incorrect inclusion of content from master branch.

On RHEL 7 based RHHI-V 1.7 the content looks like:
[root@ ]# ls -l /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks
total 36
-rw-r--r--. 1 root root 2264 Jan 24 16:39 cache_setup.yml
-rw-r--r--. 1 root root 1331 Jan 24 16:39 fscreate.yml
-rw-r--r--. 1 root root 3637 Jan 24 16:39 main.yml
-rw-r--r--. 1 root root 2222 Jan 24 16:39 mount.yml
-rw-r--r--. 1 root root  230 Jan 24 16:39 thick_lv_create.yml

-rw-r--r--. 1 root root 2002 Jan 24 16:39 vg_create.yml


The same content with the latest RHEL-8 looks like:
[root@ ]# ls -l /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks
total 92
-rw-r--r--. 1 root root  1427 Mar 13 09:54 bind_tang_server.yml

-rw-r--r--. 1 root root 11748 Mar 13 09:54 thin_pool_create.yml
-rw-r--r--. 1 root root  6652 Mar 13 09:54 thin_volume_create.yml
-rw-r--r--. 1 root root  3327 Mar 13 09:54 vdo_create.yml
-rw-r--r--. 1 root root  2951 Mar 13 09:54 vg_create.yml

Also the content of thin_pool_create.yml is totally different with the latest.
