Running NFS without root_squash? Bold. Not so smart, but bold.

NFS Squash Decoder:
✅root_squash:
Remote root becomes nfsnobody.

❌no_root_squash:
Remote root stays root.

Every user maps to anonuid.

🪦 RIP my old Dell PERC H310. You had a good 10 year run. Now replaced with a new to me LSI 9300-8i. I hope it gives me another 10 years or more.

My wife has said the same. I see it as another life insurance policy. I'm working on simplifying and documenting my setup so she can just hand the documents to someone and they can fix it or tear it down.

Is it still a homelab if the whole family notices when it goes down?

Feels less like tinkering, more like running a business… with impossible-to-please clients.

Congrats! You’re now CIO, CTO, sysadmin, and helpdesk. All unpaid.

And yet somehow… it’s still fun.

I spent 2 years running the Arr suite in unprivileged LXC containers.
It was *fine* until NFS ghosts, stale handles, and permission errors drove me insane.

I rebuilt it all in Docker Compose. It finally works.

Yeah, I’ve been radio silent. Between upgrading the blog and dodging the flaming dumpster fire that is U.S. politics right now, social media just hasn’t been the vibe. But don’t worry, I’m still building, still planning on writing more, and still helping orhers anyway I can. Hang in there.

Some of you are asking why I brought my Arr stack back to Docker from LXCs. I'll have a post about my reasons soon.

Also others are asking for my complete Docker Compose and .env files. I will share these with everyone soon.

Right now I'm focusing on the blog to bring you a better user experience.

KryptikWurm @diymediaserver.com · Jun 15

After months of juggling Sonarr, Radarr, SABnzbd, etc. across separate LXCs, I’ve moved the entire Arr stack back into a single Docker VM.

Less overhead, easier updates, and cleaner permissions.

Sometimes consolidation beats isolation.

Testing out Debian 13 (Trixie) for my NAS. Feels a lot less bloated than Ubuntu 24.04. Once released, I'll be migrating all of my VMs and LXC containers back to Debian. I just feels more like home than Ubuntu ever did for me.
