Nice, thanks for the link. I might have to grab a couple to see what else I can do with them.

Sorry, yes! I've got my head in another non-electronics project right now and was thinking of the wrong thing.
We've been seeing these electronic tags on sale items at Walmart for the past few years. It's been a few months since the last time we were in the store, but last weekend we noticed ALL items now had small two-color OLED price tags on them. I don't know if that means we're just lucky enough to be one of the first to get the new tech, or that the chain had already started rolling them out well before the article, but they're definitely out there. I'd actually love to get ahold of some just to play with them, although seeing the prices of OLEDs on ebay makes me wonder how any store is saving money by using them.
There's also the issue of very little (if any) used EVs on the market, and in an affordable range. Most people are looking for a reliable used car for around $1000-$2000 US, and the cheapest EV I have seen is around $7500. And there's always the question of what condition the batteries are in -- if you had to replace all the batteries in a used EV then you easily doubled the cost of it. Fortunately it seems like Tesla is the only manufacturer asinine enough to seal their batteries, other manufactures allow replacement of individual cells which will really help in the used market.
Heh sorry about that. There's also a zfs conversation going on where I had suggested disabling the 'dedup' option. I've never heard of dedupe being used in the context of the shell history, so yeah, I got confused.
I only include it because pretty much every guide on zfs setups recommends disabling it these days. I don't believe it's anything I've every had to use despite several drive crashes over the years.
I think this is the only change I've made that affects my history... It simply ignores multiple copies of a command when you repeat it multiple times, making it easier to up-arrow through the unique things I've executed.
export HISTCONTROL=ignoredups
Nothing wrong with used servers, that's the only thing I've ever run. Ebay has provided a ton of equipment to me.
I've never used TrueNAS, but my experience with ZFS is that it could care less what order the drives are detected by the operating system. You could always shut down the machine, swap two drives around, boot back up, and see if the pool comes back online. If it fails, shut it back down and put the drives in their original locations.
If you are moving your data to new (larger) drives, before anything else you should take the opportunity to play with the new drives and find the ZFS settings that work well. I think recordsize is autodetected these days, but maybe for your use things like dedup, atime, and relatime can be turned off, and do you need xattr? If you're using 4096 block sizes did you partition the drives starting at sector 2048? Did you turn off compression if you don't need it? Also consider your hardware, like if you have multiple connection ports, can you get a speed increase by spreading out the drives so you don't saturate any particular channel?
Newer hardware by itself can make a huge difference too. My last upgrade took me from PCIe x4 to x16 slots, allowing me to upgrade to SAS3 cards, and overall went from around 70MB/s to 460MB/s transfer speeds with enough hardware to manage up to 40 drives. Turns out the new configuration also uses much less power, so a big win all around.

Damn, it was still running? Not that I still remember my username or password, but damn...
I'm still trying to figure how anyone (including Musk) ever thought he was a genius? Like ok so he has a lot of money that he throws at interesting problems, and those problems attract actual geniuses to solve, but what has Musk himself ever done except be an employer? It reminds me of all the talk about how Edison was supposed to be a genius, when the reality was that he ran a sweatshop to steal other people's hard work.
