removed zfs cannot create new zfs insted

[ilia]

i made a zfs volume (Node->Disks->ZFS Create zfs)

after deleting i cannot remake it, no device available (no Disks unused),
the disk is sdb and for some reason when running

ls /dev/disk/by-label/

it prints old zfs volume. (i tried rebooting and installing the proxmox node but no change)
something is stored on the cluster

found a solution

cfdisk /dev/sdb

and removed all partitions
