I believe you can accomplish this with partitioning the disks with sizes that match the smallest disk too for zfs. You still have all the same reliability issues though and there's probably some kimd of performance hit too. Though yoy could then likely set copies=2 or something to add some redundancy to bad sectors at least and get a little better there than the linear mapping with dm or lvm2 on linux. You should the. Also be able to grow the array but like the linear mapping it's going to be unbalanced as to where free space is. My personal preference in this kind of situation is to still just use lvm2 to jbod the disks together if I;m fine with the risks of losing it all anyway, and just setup a good backup strategy. More because I'm familiar with it and all the tools than other setups. I think zfs might give me more early warning signs of a disk with an issue but the performance hit isn't always worth it to me there. I've got an 8tb raid0 nvme ssd array (4x2tb) setup to give me some blazing fast local storage for a few key VMs thst I just backup daily to the zfs storage. I can get 7.5GB/s reads and 6.7GB/s writes to that array doing that and using an lvm-thin pool so I can nicely snapshot during backups.
