I'm GUESSing it's the 'snap' fault. /test/stor1 is probably translated into
something else under /var/snap/lxd ? Or perhaps snaps doesn't have acces to
directories outside /var/snap (your 'vm' storage pool says it might be the
case)?

You can also try using packages (not sure if it exists for debian),
building lxd yourself, or switch to ubuntu. I've tested dir (some time ago)
and zfs (my main backend for lxd), both works.
