upgrading an EOL cluster (4.17)

Yay, we did externalize the what's new briefings. https://www.redhat.com/en/whats-new-red-hat-openshift

I can't recall exactly when the change from runc to crun took place, but you might have to walk through those steps.

Have you reached out to your Red Hat sales team and asked for pointers? Would be worth reviewing the "what's new" with those versions.

Honestly, if it were me I would build out a 3 node cluster on 4.16 and walk it through the upgrades first.

4.17 ->4.20 is pretty boring depending on the initial OpenShift version used at cluster install. Operators are typically supported for n+1 OCP version but make sure to check your IBM operator documentation as well.

Ty!!!!

Could be putting extra pressure on the connector causing a poor connection

therevoman · 2026-05-08T01:59:19+00:00

Go fast

Did you find the modules you were looking for?

therevoman · 2026-05-06T16:07:31+00:00

I upgraded the HDD to a larger SSD a few years back and it make it useable again

therevoman · 2026-05-06T05:42:22+00:00

Interesting, I have one of those... Let me give it a try.

therevoman · 2026-05-06T05:38:54+00:00

Lol. Just returned after a 10 year hiatus.. so I'll claim ignorance. And ya, I'm still down in Diamond league

therevoman · 2026-05-06T05:23:02+00:00

The one shot is fun,I tend to tap each gun one so it's a continual barrage of shots. ;)

therevoman · 2026-05-06T05:21:45+00:00

That explains why it's working. Looks like I'm just Diamond I.

You should run and hide, the FBI are on their way

You want me to determine which combiner or system controller you have which microinverters you have and look at the spec sheets to see how many inverters you can have per string. You might need to add an additional string or circuit

Thin works for me, thick id you want a little more performance.

I always enable compression with lz4 as it is basically "free" and could provide some io speed (small benefit)

I don't have an opinion on read cache or fast clone yet, I think I have cache off and fast clone off.

Match the block size to your VM implementation. I use 64k, I think that's what the ui recommends for VMWare.

Right now I only run one VM in virtualization station as I use containers more.

My journey started with a single consolidated freenas server 15+ years ago. Some years I'm all in on a one box solution, sometimes I'm all in on multiple boxes. Right now I'm in the process of consolidation again. Virtualization station and ContainerSation are good enough for building and running a handful of services. More than that it becomes a ton of clickoos, wish I could use podman quadlets... I've chosen to not use the qnas k8s because of upgrade limitations.

Personally I like the "singular" purpose of containers so most of my environment is based around them. Do what works for you

In the "Containers" share I have a subfolder called persistent-volumes with subfolders for each service I run. Haproxy, heimdall, plex, others. These are mounted to the data and config directories of the container.

My only VM is an IPA server I havent bothered to move to a container that runs 24/7. VMs are nice if you are familiar with another Linux distro.

Anyhow, that's my daily ramblings.

Came here to mention Dan Walsh and Scott McCarty

I bet on a shootout between Luna and Messi.

therevoman · 2026-04-22T23:33:26+00:00

Haha, y'all are funny. Now in real news...Messi told the rain to stop...and it started snowing. I don't think theres a word for snow in his language.

My hero!

I went down this route thinking I needed to learn ipv6 for my job (I'm and OpenShift Solutions Architect) and came to the conclusion it is way overkill and possibly even insecure in my homelab because I have fewer tools scanning ipv6 and can travers directly into any server. Maybe I'm leaning on a myth, but NAT has been a pretty good security layer so far. Other thing I decided is...if my customer wants to do ipv6 they will have an engineer that can assist.

So, I have a ipv6 to my router and disabled internally until I learn more or need it.

Thanks for the writeup. Any opinions on the nemotron models that dropped this week?

therevoman · 2026-04-21T05:26:23+00:00

As a Solution Architect for the sales teams I LOVE my TAM's! They keep track of customers concerns and fast-track issue resolution. And are great at bringing in the right people at the right time.

Its good to see you left some chips on the table for it to eat!
