Hi, I'm currently trying to mirror a couple of yum repositories and the only tool that seems to be available for this is reposync. Unfortunately reposync for some inexplicable reason seems to use the yum config of the local system as a basis for its work which makes no sense and creates all kinds of problems where cache directories and metadata gets mixed up. Are there any alternatives? Some

Hi, I'm trying to setup the provisioning of new OpenStack hypervisors with cinder volumes on them. The problem is that kickstart doesn't allow dashed in volume group names? I tried this: volgroup cinder-volumes --pesize=4096 pv.02 and this: volgroup cinder--volumes --pesize=4096 pv.02 but in both cases I end up with a volume group named "cindervolumes" on the system. Any

Hi, I''m trying to find a way to configure the firewall on centos systems using puppet by copying the /etc/sysconfig/iptables file and restarting the iptables service. That part is simple to accomplish. The twist I need to add though is that I only want to do this if a copy of that file for the node exists on the server. If this file doesn''t exists then I want puppet to not

Hi, I''m trying to get puppetmasterd and puppetd to communicate properly with each other but there seems to be a problem with how puppet determines the hostname of the machine. Both daemons run on the same machine with the hostname "nexus" but when I start puppetmasterd with "puppetmasterd -v -d" I get the following output: ... info: Creating a new SSL key at

Hi, I'm trying to build a redundant duo of firewalls/routers/gateways and I'm thinking about not putting any disks in them and instead using a usb-stick raid-1 as storage. Has anyone any experience with this? Since the machines will be running pretty much only iptables, conntrackd and keepalived there is not going to be a lot of disk activity going on and the plan is to do all the

Hi, today a couple of Hypervisors got restarted due to a power outage. While the systems and the VMs on the are running fine multicast traffic between the guests is no longer working. I generate multicast udp packet using iperf in the guest and check on the host using tcpdump: tcpdump vnet0 => multicast packets are visible tcpdump vlanbr8 => multicast packets are visible tcpdump em1.8

...ave the relevant VLAN (VLAN 48) with the assigned IP address of 192.168.48.101 and the range of ports (Gi1/0/1 - Gi1/0/8) assigned to that VLAN. Seems - and acts - like a legitimate setup and works fine, except for this particular instance. Thanks. Boris.

Andrew and Dennis are spot on. Their conclusions about your server being connected to an access port and not a trunk port would be my conclusion as well.

This is pretty epic if true. I'm installing some Fail 2008r2 now to check. Is your hypervisor running CentOS 6 or 7? -- Sent from the Delta quadrant using Borg technology!
