[SOLVED] PBS root disk on ZFS (mirror)


Sep 8, 2021
Hello everyone,
In the PBS installation interface, it is possible to install the system on a ZFS pool (Target hard disk / Options). But which Advanced Option to choose to have two mirrored disks : Do I have to select 2 disks with Raid1 option and 2 copies ? I actually don't understand the raid0 and raid1 options. With 2 disks dedicated to my system apart from raidz-1 2 or 3, I was thinking of using the mirrored option...
