Bug Description
Conventionally, ZFS is contained within GPT partitions. While setting up zfs using ubiquity, legacy/bios booted system use MBR partition tables. This is especially problematic since MBR partitions are restricted to 2TB.
GPT disks must contain a "Bios_Grub" partition in order to be bootable from Bios/Legacy systems. This partition can be created using the command "sgdisk -a1 -n1:256K:+768K -t1:EF02 <disk>", where all the 1's in that command specify an available partition number.

Thank you for your report.
This has been reported in bug 1856863. partman_auto creates a GPT when the disk is bigger than 2TB but I'll verify it also creates a bios_grub partition on legacy systems.
I'm marking this bug as duplicate.
