[Starlingx-discuss] PXE-boot error with 5.0 build

[Penney, Don]

The error in your screenshot indicates trouble retrieving the initrd. I would check the dnsmasq logs in daemon.log on the active controller. You'll see the DHCP request and response there, and should see tftp requests for the pxelinux.cfg file, followed by the bzImage (kernel) and initrd.

In my test, the initrd is the last of the three files, so it's surprising there'd be an issue on that one and not the earlier files. Maybe the logs will shed some light for you.

Example from my system:
[sysadmin at controller-0 ~(keystone_admin)]$ tail -f /var/log/daemon.log | grep dnsmasq

Subject: [Starlingx-discuss] PXE-boot error with 5.0 build

[Please note: This e-mail is from an EXTERNAL e-mail address]
Hi,

We are trying to bring-up Starlingx in ALL-IN-ONE DUPLEX mode and using the 5.0 release-build.
The first node is coming up properly but the second node is failed in PXE boot.

Note: We have created OAM and MGMT VLAN over same interface and enable the pxeboot on the interface. This networking was working fine with starlingx:4.0 and we are seeing the issue with 5.0 only

The screen-shot is attached for your reference.


Thanks,
Ankush
