If you use a Mac and back up your data with Time Machine, and you decide to upgrade to Tahoe for some reason, your backups could stop working for various reasons. My advice is to format the drive properly, not just the volumes contained within GPT, because Microsoft could potentially break your workflow.

Tahoe Time Machine Failure on Samsung T7

ISSUE Every good storage failure starts innocently. Plug in a brand-new Samsung T7. Select it in Time Machine. Click “Use Disk.” Allow macOS to format the drive automatically. Let the backup run. It may even complete once — maybe even a few more times.

TrueNAS (Graphite Exporter) — ZFS + SMART
Because The Goldfish Brain is good for something.

@stefano Containers are the train cars; the host is the locomotive. If you keep bolting random test equipment onto the locomotive and it fails, all the cars stop, because none of them move without the engine.

@stefano Containers are musicians; the host is the conductor and the sheet music stand. You can hand one musician a weird experimental instrument, but if you start swapping out the conductor’s brain mid-performance and it crashes, the whole orchestra stops.

@stefano That’s like reprogramming the airport’s radar system so one passenger, a dev of radar apps, can test a new phone radar app.

@stefano you need analogies …

That’s installing a GUI on a router so you can debug a web app.
