Speak softly and carry a big stick

Trump might not talk softly, but he does have a big stick.

While the left is melting down and calling us stupid, Trump announced that he would impose a 25% tariff on Mexico and Canada if certain conditions were not met.

The opposition party in Canada is yelling at the government to fix it fast, before January 20th.

The Mexican President turned back a migrant convoy before it reached the US border.

Turkey Leftovers

My son made it home from collage late Wednesday. So my wife made a turkey for him tonight. To go with the larger turkey, we will have for Friendsgiving on Saturday.

It was nice to have young muscles on call. I had him move the arbor press. I can now recover my table saw and work on some woodworking projects.

It was pleasant listening to him talk about classes. It was a bit sad that I knew much of the theory of what he was working on/learning.

He has decided he is going to get an internship to get some hands-on experience to go with his classroom and lab work.

I’m proud of him.

Nerding one: OVN networking

I thought I had a handle on OVN networking. My tests were showing good connectivity. It should have just worked.

I’ve had trouble wrapping my head around some concepts in OVN. One of them finally clicked, improving my life.

When you create a logical switch, nothing is connected. You can create logical switch ports which must be attached to a logical switch.

There are three types of ports I deal with, ports that are connected to virtual interfaces, such as a VM creates, ports that are attached to logical routers, and ports that are connected to the local network.

It was my understanding that if I wanted a high availability network, I would need to configure a distributed gateway.

When I did, I got dropped packets. If I reduced the HA gateway to a single node, no more dropped packets. Also, no HA.

An article appeared. It indicated that I needed a different logical switch to make everything work.

The issue was that the DMZ is a logical switch that is a part of the physical network. My logical router is attached to the DMZ, so attached to the physical network.

What I required was a second router to be that gateway. It exists on the physical network on multiple chassis, but it is connected to the JOIN logical switch, which is stable. This fixed all my issues with that part of the networking.

Another step in the right direction.

Nerding two: Moving machines

THE PSU for one set of machines is running near limits. I need to move at least one node to a different PSU.

The correct method to use is to create a new subnet for the new location, feed it back to the primary router, and start moving from an L2 network to an L3 network.

The issue is that Ceph wants all the data nodes to reside on the same network. The public side is also one network.

The fix was in my hands, see above about OVN.

I would move the OSD’s from the physical network to a logical network, and it all would just work. All testing showed it would work.

I started the process, and it appeared that the OSD’s did not like living on two nets at the same time. So I moved to a single network, the new network address range.

There were still some issues, so I moved all the hosts and the monitors to the new network.

And lost access to the cluster. It just stopped responding.

The indicated methods of bringing it back to life failed.

I ended up having to manually edit about 40 files to restore a working configuration.

Everything seems to be working now. But it is 0300 and I’ve been fighting this for 5 hours.

Conclusion

I hope you had a great Thanksgiving.

Question of the week

The Department of Education was created by an act of congress. The President can’t dissolve it with the stroke of a pen. That would require another act of congress.

What he can do is RIF the heck out of it, reducing the staff to a more manageable level.

My question for you is: What tasks, if any, should the DOE still perform?
