What kind of errors you're getting? First what you can try is to run 'dpkg --configure -a'. If that doesnt help we need more information on what's going on.
Get a REALLY good on-site support deal for your hardware. You also may need to adjust TTL values on your network stack.
It wasn't for nothing, you got some learning out of the experience and a story to tell. Good luck with the new system, maybe hold upgrading that to testing for a while, there's plenty to break and fix even without extra quirks from non-stable distribution :)
Have fun and feel free to ask for help again, I and others will be around to share what we've learned on our journeys.
You're not worrying for nothing. Losing wall power will shut down the drives and as usb-cradle is generally slower than "proper" drive bus it's more likely that some write operation is going on when power is lost and that'll potentially cause data corruption. Obviously not every power outage will cause issues, but I'd say it's a higher risk with USB-drives than with drives on a SATA/m.2 bus.
But no matter what your setup is, raid is not a backup. All kinds of things can happen which cause loss of data and you should plan accordingly. If all you have is two drives on usb-cradles I might choose to use one of them as a offline backup disk and one for 'live' data so that it's more likely that at least one of the drives is functional even after power issues or whatever, but that approach has it's own problems too.
There's a walkman model which is pretty much just that which runs some flavour of android but I don't know who they think their customer base is as the pricing is absolutely stupid. Top of the line model has gold plating and a nice 4k price tag. Also it apparently has 'oxygen free copper' and other audiophile bullshit, but no FM tuner.
And then there's a ton of similar products from China but no idea which models (if any) are actually useful.
I had a two (or maybe a bit less) bitcoins on my wallet back in the day. I sold them for ~20€.
Well, the touchscreen part and maybe a bit more, had the same reaction on many directors at Nokia at the time. I don't know if they feel like an idiot, but at least you're not alone.
Cameras don't stop anyone, but I still have few recording my yard. It's more of a hobby and I'm planning to integrate person detection on those to home automation but for me it's also a small piece of peace on my mind. Should someone steal my car trailer (or a car) I'd have some footage for the police and insurance. Also a while ago we had a decent storm around and we weren't at home so it was nice that I could check for possible damages remotely.
But absolute majority of time I don't even think about them. I don't have any notifications enabled, I'm not interested about neighbors cat running across our yard or getting interruptions every time someone on the family comes or goes. And while Frigate has some AI things built in, the whole thing runs locally. There's no way I'd install nest or some other camera which sends/stores data to anywhere which isn't 100% in my control.
I haven't tested lvm on arm-based systems, but if it doesn't automatically locate them you could try pvscan/vgscan/lvscan.
Rootfs location is passed via kernel parameter, for example my grub.cfg has "set root='hd4,msdos1'". That's used by kernel and initramfs to locate the root filesystem and once 'actual' init process starts it already has access to rootfs and thus access to fstab. Initramfs update doesn't affect on this case, however verifying kernel boot parameters might be a good idea.
And all of your data on that machine is gone as well.
