Fixed In Version: Doc Type: Bug Fix
Doc Text:
Cause: Some OpenStack environments might enforce a policy where VMs can't boot with ephemeral disks and need to boot from a cinder volume. Consequence: In these cases, it is impossible to install OCP with IPI because even when configuring the master and worker nodes to boot from volume using the rootVolume setting, the bootstrap node would still boot from ephemeral disk. Fix: Have the bootstrap node follow the rootVolume settings from controlPlane machine pool. Result: It is now possible to install OCP in OpenStack environment that enforce a policy where VMs can't boot with ephemeral disks.

Description Pierre Prinetti 2020-04-27 11:42:25 UTC
+++ This bug was initially created as a clone of Bug #1820434 +++

Description of problem:

  OCP4.2 IPI on RHOSP does not deploy bootstrap node using volume boot.

  In some actual RHOSP13 environments, only the volume boot is available.
  So, the use of image boot is restricted, because
     - RHOSP operation becomes simple or easy at the migration and system trouble.
     - some end user customers do not recognize the difference between image boot and volume boot

  In this case, "openshift-install create cluster" by OCP4.2 IPI on RHOSP fails.

Version-Release number of the following components:

  RHOCP 4.2

How reproducible:

  $ openshift-install create cluster

  Note: The OSP environment has a limitation, so only the volume boot is available.
Steps to Reproduce:
1. openshift-install create cluster

Actual results:

  "openshift-install create cluster" failed.
Expected results:

  "openshift-install create cluster" succeed.
