Sometime your shell scripts get out of control. Sometimes you are proud of them. Sometimes….both.
I need to be able to re-add a bunch of nodes to an OpenStack cluster on a regular basis. Yes, I could do this with Ansible, but, well, Ansible is great for doing something via SSH, and this just needs to be done here and now. So shell is fine.
This started as a one liner, and got a bit bigger.
Continue readingAmpere has two models of Servers out: Falcon and Mt. Jades. The Falcons are the older one, and make up many of our utility servers.
I recently had to get in to a serial console on the machine. The IPMI address hosts a web console. From that you can get a serial console on the server, but you need JNLP, which stands for Java Net Launch Protocol. It is implemented by IcedTea in OpenJDK: icedtea-web is the name of the RPM on Fedora 34.
In my quest to automate the testing of the Linux Kernel, I need to automate the build of the Linux Kernel. To build the Kernel, you need the requisite packages. What are they? Let’s find out.

for JOB in $( bkr job-list -o $( bkr whoami | jq -r '.username' ) | jq -r ".[]" ) ; do bkr job-results $JOB | xpath -q -e "string(/job/recipeSet/recipe/@status)" ; done |
Ampere Computing chips run the ARM64 instruction set. My laptop is a Dell running x86_64. In order to edit locally, but build remotely, I make use of servers in our datacenter. These are the steps I am taking.

Continue readingSome 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:
jade09-r097
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 readingMy 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.
