One of our ironic baremetal nodes was suffering a cleaing failure. Fixing it was easy…once we knew the cause/Continue reading
Enough of us are looking at the cluster that I want an easy to read snapshot of the node state. So, I convert the csv output of the openstack command into a simple HTML table.Continue reading
Some custom jq for RegEx selection of OpenStack Ironic baremetal nodes. Our Server types show up in their names. I want to be able to build lists of only the Mt. Jade Servers, which have names that look like this:
openstack baremetal node list --sort provision_state:asc -c UUID -c Name -f json | jq '. | select(.Name | test("jade."))'
While I tend to think about the nodes in OpenStack term, the people that physically move the servers around are more familiar with their IPMI address. We have several nodes that are not responding to IPMI requests. Some have been put into the manageable state, some are in error.
Here’s the query I used to list them.
If an OpenStack server (Ironic or Nova) has an error, it shows up in a nested field. That field is hard to read in its normal layout, due to JSON formatting. Using jq to strip the formatting helps a bunch
The nested field is fault.details.
The -r option strips off the quotes.Continue reading

My team is running a small OpenStack cluster with reposnsibility for providing bare metal nodes via Ironic. Currently, we have a handful of nodes that are not usable. They show up as “Cleaning failed.” I’m learning how to debug this process.Continue reading
Time for a change, and a big one at that. As of September 20th, I am now a full time Employee of Ampere Computing. I am in the Software Development team, working on Open Source stuff. That means Linux Kernel and Open Stack, among other things.
I’ll post more on why in the future. Why I left Red Hat, and why I specifically chose Ampere. Both deserve a well formed explanation, as both are very important to me. My head is not there yet, it is in code and machines and processes.
I’m getting Amped.
Technical stuff has been hard to collect this summer. Having a couple weeks off hadn’t helped. So here are some pictures instead.Continue reading
Dad gave me back the lathe I gave him….he has other toys. Including a production system for firewood. So I got same maple (I think) and rough turned some bowls.Continue reading
I don’t understand, yet, why this works, but it does. Thanks to this post
