| Doc Text: |
The 'readcache' and 'readcache size' options for virtual disk optimization (VDO) are not supported on VDO volumes based on Red Hat Enterprise Linux 8, which includes Red Hat Hyperconverged Infrastructure for Virtualization 1.8. These options are now removed so that VDO volume creation succeeds on version 1.8.

As readcache is no longer supported with VDO thanks @sas for the information But the deployment is trying to set that and it fails. The file where the issue occurs /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/vdo_create.yml /etc/ansible/hc_wizard_inventory.yml contains 'readcache' operation VDO Readcache related attributes should be removed from 2 places :
1. cockpit plugin
2. gluster_ansible_infra
VDO Readcache related attributes are:
"readcache": "disabled",
"readcachesize": "0"
