[SOLVED] PBS root disk on ZFS (mirror)

[PierreD]

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...

After rereading a bit of ZFS documentation, my ideas are a little clearer. The number of copies in "Advanced option" has nothing to do with the chosen redundancy (see https://jrs-s.net/2016/05/02/zfs-copies-equals-n/). The Raid1 option of the ZFS installation must correspond to "mirror". Why not call it that?
