Start container without attached storage volume

LXD

Is there a way to failsave add storage volum to container?

Scenario: /backup/… on the host server (something like raid mirror on big rotational disks)

lxc storage create backup dir source=/backup/$ct/
lxc storage volume create $storage $disk
lxc storage volume attach $storage $disk $ct $disk $path

In case if something happened to /backup mount I want container to be able to start without manual detaching volume:

lxc storage volume detach $storage $disk $ct

Is it possible to do?

Set required=false on the disk device.

lxc config device set $ct $dist required=false
