Fixed In Version: puppet-ironic-9.5.0-2.el7ost
Doc Type: Bug Fix
Doc Text:
Originally, the DHCP server configuration file for Ironic Inspector was not set up properly to handle hosts that were using UEFI and iPXE. Consequently, any such host might fail to boot during Ironic Introspection. The problem has been fixed and the `/etc/ironic-inspector/dnsmasq.conf` has been updated to handle this situation. As a result, hosts using UEFI and iPXE can properly boot during Ironic Introspection.

Description PURANDHAR SAIRAM MANNIDI 2017-08-08 09:19:42 EDT
Description of problem:

Ironic introspection loops over ipxe.efi for UEFI boot_mode

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start the ironic node introspection
2. Node loops at PXE booting after downloading ipxe.efi

Actual results:
Node loops at PXE booting by downloading ipxe.efi

Expected results:
Node should continue with introspection process.

Additional info:
To reproduce the issue in lab, I added dhcp-match=set:efi,option:client-arch,9 as well.

I have another customer that seems to be hitting this issue attaching screenshot of where their remote console is looping on introspection with UEFI.

Comment 13 Bob Fournier 2017-10-12 16:05:43 EDT
stphilli - its likely, would have to see a tcpdump of the dhcp transactions to know for sure.  We recommend making the change to /etc/ironic-inspector/dnsmasq.conf as shown above.  The fix has merged upstream and should be in next 10.z release.
Comment 14 PURANDHAR SAIRAM MANNIDI 2017-10-12 21:36:40 EDT
stphilli it looks like a networking issue to me. PXE boot itself didn't start in the first place and this bug resolves PXE boot loop.

Comment 22 Bob Fournier 2017-11-02 10:54:55 EDT
I made 2 minor edits to doc text, otherwise it looks fine.
- changed iPxE to iPXE
- removed "over PXE"
