ZFS pool not shareable via NFS

From my current OMV 7.7.0-2 I have a ZFS pool that is mouted to /mnt. The Debian Update I was offered then destroyed my current version so that the NAS could no longer boot. A reinstallation of OMV 7.7.0-2 works, however, I can no longer release my ZFS pool for an NFS connection, since I only ever appear the other systems such as XFS, EXT4 etc. as release medium. Does anyone have any info for me how I can release the Pool, which is mounted /mnt via NFS?

Thank you..

Nachdem mir mein NAS letztens 64 Updates für Debian angeboten hatte ist mein Server danach nicht mehr gebootet. Eine Neuinstallation von omv 7.7.0-2 klappte zwar, auch die Neuinstallation des zfs Plugins ging und ich konnte meinen Pool auch wieder importieren... aber ich bringe nun keine Freigabe des Pools per NFS in meinem Netzwerk mehr hin, da ich über das omv GUI immer nur EXT4, XFS oder BTRFS Filesysteme hier freigeben kann. Hat sich da etwas in der letzten Zeit geändert oder habe ich einen Gedankenfehler?

can you explain how i install a proxmox Kernel... is there a how to?

1. Yes omv-extras are installed on OMV

2. Yes i have installed openmediavault-zfs plugin for OMV after installation omv + omv extras
