i try using ZFS

zpool create -f -o ashift=12 sdpool /dev/mapper/pve-data

error
cannot open '/dev/mapper/pve-data': Device or resource busy
cannot create 'sdpool': one or more vdevs refer to the same device, or one of
the devices is part of an active md or lvm device

Hi,
to share you have to setup nfs.

zpool create -f -o ashift=12 sdpool /dev/mapper/pve-data

pve-data ist mounted you can't use a mounted dev.
and you should only use hole disk fore ZFS and no lvm pools.

yes i want full disk, normally what are an path that should be used ?

 

[wolfgang]

use lsblk to see what disk are in your machine and how they are used.
