Can we have an easy way to permanently remove disks from a pool/array? Let's say I need go down by one drive because one is about to fail and I don't want to or can't replace it or because I don't need all that space or whatever. Or two, or three or more drives at a time. It's technically possible from within the CLI of TrueNas Scale. It's 100% not in the GUI.
I'm currently running StableBit Drive Pool (on Windows) for my NAS needs. It works perfectly for me. It's basically what you'd get if JBOD and RAID-1 had a baby. Any two or more drives, any capacity, it just works. At any point I can remove a drive either safely or to just yank it out and the software will duplicate any unduplicated files to the other drives. Expansion is even easier. Algorithms to deal with bit-rot. Preventative drive-checking and scanning.
As drives become bigger and bigger, the ideal number of drives for low-cost budget builds is 3 drives. That's the same number as the minimum required by RAID-5 when it's healthy. I don't want to have 4 or 6 or 8 drives in a computer. I don't need 100TB worth of storage and currently the HDD $/GB has a sweet spot somewhere between 12-20 TB depending on the make and model. Furthermore, SSD $/GB is really dropping and I predict that I'll only ever buy M.2 SSDs from now on and use PCIe expansion cards to mount them instead of using 2.5" SATA SSDs. To support this financial reality it'd be nice if HexOS allowed a good level of flexibility, especially when reducing the number of drives for whatever reason.
