[PVE-User] problems creating LXC on zfs pool

[Piviul]

Hi all, I can't create LXC on ZFS pool any more. When I try to add a 
LXC, in storage I can't select the ZFS store. But I have others 
container in it and I can clone LXC that are stored on ZFS; so I think I 
have no problems on ZFS...

I have tried even from command line but seems that I can't refers to zfs:

# pct create 111 
NFS-Store-vz:vztmpl/debian-10.0-standard_10.0-1_amd64.tar.gz --hostname 
printserver32 --pool zfspool
403 Permission check failed (pool 'zfspool' does not exist)

# pvesm zfsscan
zfspool

Someone can help me to add a CT on ZFS pool?

Thank you very much
