FYI, I rebuilt the system using btrfs but initially I got the same issue 

It turns out this came from running inside an unprivileged lxd 
container. After setting "security.privileged true" it was happy.

So I guess it might have been all right with ZFS, but I'll leave it as 
it is now.




You are not root or your system do not support xattr, using tdb backend 
for attributes.
not using extended attributes to store ACLs and other metadata. If you 
intend to use this provision in production, rerun the script as root on 
a system supporting xattrs.
xattr_tdb_removexattr() failed to get vfs_handle->data!
