Open Stack

Evgeniy L:

 

Thank you for the information. I have a few, possible silly/noob, question. After your email I reviewed the tcpdump again and identified that the “dhcp offer” does not contain options 66 and 67.

You can see from the excerpt of a bootp capture the highlighted portions contain the IP address offered, next server, and boot file.

 

However, in the options section there is not an option 66, tftp server name, and option 67, bootfile name.

 

SO here is the question, taking cobbler into account which file should I be editing to attempt to add these options? Is the “/etc/cobbler/dhcp.template” file the correct file; thought “template” seems to  indicate that it is not?

If not, again silly/noob, which file should I be editing.

 

Any assistance would be appreciated.

Hi Ken,

 

Fuel uses Cobbler which uses DNSMasq to provide DHCP and PXE boot, if the issue is hardware specific, you can try to search if anybody else had such problems with DNSMasq PXE boot and similar hardware.

 

Thanks,

All:

 

First off not sure I am in the right place so if I am not please be kind and point me in the correct direction. I am attempting to build an Openstack system with Fuel Community 11 with a mix servers from different manufacturers. I have successfully installed Fuel Community 11 on the master node and am attempting to add nodes to the Openstack environment. The “Dell” servers pxe boot fine, see the master node and can be added to the system. However, I have an older “Silicon Mechanics” server that will not pxe boot.

 

I have upgraded the AMI BIOS on the “Supermicro” system board to the latest release as well as the IPMI firmware. I have attempted to use both legacy and UEFI boot from the BIOS and I always see the same error. Please note that the Intel PXE release is 1.5.13.

 

“PXE-E7B: Missing MTFTP server IP address. This message is displayed when the ROM did not receive any PXE discovery tags or proxyDHCP offers and the DHCP SIADDR field is set to 0.0.0.0.”

 

I have take a tcpdump and see the dhcp discover and the dhcp offer. The Fuel master node is offering the server an IP address and is telling it what its next server and file are. 

 

Any assistance and or information would be greatly appreciated.

 

 

Regards,
