Re: [xcat-user] xCAT 2.9.1 - !remote! interfaces no longer working for makedhcp -n

[Jarrod J. <jjo...@le...>]

Sorry about that.  I was unable to sort out how to make work what was put into 2.9.1.  I have since commited a patch which restores 2.9.0 behavior, *theoretically* working for whatever use case 2.9.1 worked for (but again, I couldn't verify I didn't break that case, because that case never worked for me…)

It was two changes back to back:

Hi all,

After upgrading to 2.9.1 from 2.9.0, !remote! definitions in the network table is no longer generating the required shared-network stanzas in /etc/dhcp/dhcpd.conf for CentOS 6.

I noticed that the man page for "networks" states the format needs to now be !remote!<nicname>, so I have tried site.dhcpinterfaces=eth1,!remote!       eth1,!remote!eth1    and finally eth1,!remote!<eth1> while also updating networks.mgtifname to the same thing to no avail, I cannot get the shared network stanza to be generated anymore in dhcpd.conf.

This all worked fine prior to the 2.9.1 upgrade. No configuration changes were made between the 2.9.0 and 2.9.1 upgrade.  Any help is appreciated, thanks!


Here's what my current tables look like:

Site table:
"dhcpinterfaces","eth1,!remote!",,


Networks table:

#netname,net,mask,mgtifname,gateway,dhcpserver,tftpserver,nameservers,ntpservers,logservers,dynamicrange,staticrange,staticrangeincrement,nodehostname,ddnsdomain,vlanid,domain,comments,disable
