[Rdo-list] Issues with sysctl.conf settings on CentOS 6?

Hi all, Running packstack --allinone on a freshly installed and updated CentOS 6.5 system I encountered this error with sysctl.conf: """ Applying 192.168.122.152_neutron.pp 192.168.122.152_neutron.pp: [ ERROR ] Applying Puppet manifests [ ERROR ] ERROR : Error appeared during Puppet run: 192.168.122.152_neutron.pp Error: sysctl -p /etc/sysctl.conf returned 255 instead of one of [0] You will find full trace in log /var/tmp/packstack/20140914-225857-OebbrQ/manifests/192.168.122.152_neutron.pp.log Please check log file /var/tmp/packstack/20140914-225857-OebbrQ/openstack-setup.log for more information """ Running `sysctl -p /etc/sysctl.conf` myself I receive: """ # sysctl -p /etc/sysctl.conf net.ipv4.ip_forward = 1 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key error: "net.bridge.bridge-nf-call-iptables" is an unknown key error: "net.bridge.bridge-nf-call-arptables" is an unknown key kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 # echo $? 255 """ Removing the errant lines and re-running PackStack it just adds them back and thus fails for the same reason. I couldn't find another RDO bug covering this issue, has anyone else run into it? Logs are attached to https://bugzilla.redhat.com/show_bug.cgi?id=1141608 Thanks, Steve
