create zfs mirror with zfs marked disk

[vikozo]

Hello
i set up a new Proxmox over a old freeNAS.
i wish to add two disk, and create a Mirror with this, but the disk will not show up because they are still marked as zfs disk from the installation bevor, is there a trick to still create a mirror-0?

have a nice day

have you tried zpool import?
then if the pool can be imported you can use it or you can destroy / recreate

otherwise you could try zpool labelclear <device name>

@bobmc i could not find zpool import option in the GUI!

zpool status shows only on rpool

and
# zpool labelclear /dev/sda
failed to clear label for /dev/sda

The GUI only works if the disks are available. Open a shell on the Proxmox host and type

zpool import

if it returns a name like pool or tank, then type

zpool import pool
or
zpool import tank

zpool import -f freenas-boot
worked and now the pool is there in the GUI

and now destroy it for a new use in pve

this will clear the Disk - after they will be visible to Proxmox Gui
fdisk /dev/sdf
fdisk /dev/sdb
