Linstor property on Openstack volume types

Hi, in a openstack cloud with LINSTOR, i want to create a volume type with the linstor property “DrbdOptions/Disk/al-extents” set to 6007. This is what shows in openstack volume type section:

volume_backend_name	linstor-drbd
linstor:redundancy	2
linstor:storage_pool	cinder-pool
linstor:property:DrbdOptions:Disk:al-extents	6007

This is the actual /etc/cinder/cinder.conf file:

[linstor-drbd]
volume_driver = cinder.volume.drivers.linstordrv.LinstorDrbdDriver
volume_backend_name = linstor-drbd
max_over_subscription_ratio = 1.5
thin_provisioning_support = True
linstor_uris = linstor://10.0.10.10,linstor://10.0.10.11,linstor://10.0.10.12

When i create a volume from this volume type, i see that the corresponding resource group gets created with property set:

~$ linstor resource-group l
╭──────────────────────────────────────────────────────────────────────────────
┊ ResourceGroup    ┊ SelectFilter   ┊ VlmNrs ┊ Properties   ┊ Description                            ┊

But the resource-definition for the volume created does not have the property set:

(kolla-venv) nodo1:~$ linstor resource-definition lp volume-f45d9962-d1c2-4b52-ab63-56ac267514e5

Why is that happening? Is a problem from the driver? I’m using 2.0.0 version of Linstor driver.
