Description Osher De Paz 2022-06-20 12:33:42 UTC

Description of the problem:
Currently assisted-installer requires all nodes (master/worker/SNO) to have a minimum of 120GB disk space in one of their disks to use as an installation disk. Since openshift version 4.6 the official requirements have been changed to 100GB (ocp<=4.5 still has it 120GB) so we should update the requirements as either way we allow installation of later OCP versions.

Release version:
Relevant to all 2.5.x versions currently available.

OCP version:
Relevant to all OCP versions currently supported

Steps to reproduce:
1. Try to install a cluster with nodes having a disk of 100GB
2. Take a look at hosts' state. It will display as insufficient with message that no disk is available for installation

Actual results:
Hosts are in "insufficient" state.

Expected results:
Hosts considered "ready" to participate in cluster installation.
