OTOH, TrueNAS is designed to run from it, so I would assume it handles its root drive with care. Perhaps you can disable verbose logging and such. > If I reinstall TrueNAS on a new USB stick, will it automatically see the > previous pools and such or do I have to set everything up again fresh? Pools and their metadata are stored inside the pools. In Linux, you don’t even need to set up fstab. The pool stores its mount point internally. So you just start the zfs daemon and it does everything magically. > In other words, will I lose data? You won’t lose data, of course. But I think you meant settings(?). Probably about users, shares and such. Perhaps it has an export feature which can be run periodically. > This also includes if it is encrypted. Encryption is a built-in ZFS feature.

I assume the kernel is built like many general-purpose-distros: with everything in it you may need for the purpose. But since it is BSD, it may have driver issues (availability and stability for certain cards). Sometimes, when I read news about a new product, people complain that the NIC is not Intel and will thus cause problems with BSD, especially with niche stuff like the Killer-brand ethernet cards. > and recompile.

I don’t see a connection between being a “binary thing” and hardware change. Your gentoo is also a binary thing once it is compiled. ;-) > I also found out something power wise.

It must be old then, and back then, idle power was a non-issue. > My main rig consumes just under 200 watts. Not to bad That’s a very lot for my taste. With a lower mid-range GPU (110 W Radeon R7 370) and one spinning rust, my 8-year-old PC used to idle at 50 W. Without the HDD and with Intel graphics it is now at 27 W. Still not a good number when compared with today’s hardware. > but a Raspberry Pi would likely consume 15, 20 watts max according to what > I've read. My 3B idles at 5 W tops, I think.

I'm looking at 4 bays but also found a 6 > bay. I think 6 is overkill tho. My four-bay NAS has four 6 TB drives and it draws around 50 W at idle. But that’s because it is a server board, incuding IPMI chip (and—interestingly— an internal USB-A for an OS stick). And it’s Haswell generation, so almost a decade old design. For this reason I switch it on only every few weeks or even months and only keep it running for a short time. -- Grüße | Greetings | Salut | Qapla’ Please do not share anything from, with or about me on any social network.
