Provisioning hosts using Red Hat Satellite 6 Capsule Server fails when download policy for kickstart repos are set to On Demand

Solution Verified - Updated

Environment

  • Red Hat Satellite 6
  • Red Hat Capsule 6

Issue

  • Provisioning hosts using Satellite Capsule Server fails when the Satellite kickstart repos are set to On Demand and the Capsule Server synchronization is also set to On Demand.

  • The Satellite Server is able to provision successfully, but provisioning using Capsule Server fails when the kickstart repositories have the On Demand download policy.
    Example, when provisioning a RHEL8.3 vm from the capsule, where the RHEL8.3 Kickstart repo is set to download policy "On Demand", dracut captures below logs during provisioning:

[   17.516924] rhel83test dracut-initqueue[1141]: anaconda: successfully fetched stage2 from http://cap6.example.com/pulp/repos/my_org/baseline_2020/RHEL_8_x86_64/content/dist/rhel8/8.3/x86_64/baseos/kickstart/
[   17.633120] rhel83test kernel: loop: module loaded
[   17.656135] rhel83test dracut-initqueue[1141]: losetup: /tmp/curl_fetch_url1/install.img: Warning: file does not fit into a 512-byte sector; the end of the file will be ignored.
  • Capsule Server fails to provision hosts due to vmlinuz not being found.

Root Cause

  • If the kickstart repo for the Capsule Server is set to On Demand, the kernel will not be available for the host boot.

  • The issue can occur unexpectedly due to On Demand being the default synchronization policy for new repositories beginning in Satellite 6.3.
