#3957 Multiple issues with makedhcp and service node pools

[Russell]

Hi all,

I am seeing the following problems with makedhcp in both xCAT 2.8.2 and 2.8.3:

• When networks.tftpserver is blank as documented for service node pools, the DHCP subnet entry in /etc/dhcp/dhcpd.conf does not contain a next-server line that points to itself. As a result, nodes fail to boot.

This is affecting an upgrade in production. Are there any quick patches available to fix these issues?

Doesn't look like I can edit the title on this, but this ticket started out with multiple issues but the 2.8.3 upgrade corrected all of them except for this one I listed here :)

Can not recreate this problem on my 2.8.4 MN.

Hi Guang,

Is the 11_10_0_0-255_255_0_0 network the only one you have in your networks table? Were there any commits to the 2.8.4 code that could be responsible for this being fixed?
