Backup server installed on ZFS

[Bran-Ko]

I installed backup server on 2x SATA 1TB disk. How I can move this installation to another 2x SATA 4TB. And after that I wan to replace old 2pcs 1TB HDD with another 2pcs 4TB. Finally I want to use 4pcs SATA 4TB with RAIDZ ZFS (RAID5).

I thought that only things what I need to do is - add disk to zpool and change from mirror to raidz.

But I can't add disks to rpool because there are another partitions

I don't know how to deploy BIOS boot partition on /dev/sdc and /dev/sdd. And the same with EFI system

you can't switch from mirror to raidz or expand a raidz..

Online raidz expansion will be available this or next year:

iit doesn't be done online. server can be stopped (it is backup server)

if you have spare disks, you can shuffle your datasets around from one pool to another with zfs send/recv.
