Removing xcp-persistent-database resource

[ha_tu_su]

Hi

I am experimenting with XOSTOR. I removed the SR related to XOSTOR and then started deleting the resources from command line using linstor resource-definition delete <rd_name>. I am now only left with xcp-persistent-database but I am not able to delete it because it is always in use by the host which is linstor-controller. Can anyone suggest me how I can delete this resource?

I did read this reply from @ronan-a: https://xcp-ng.org/forum/topic/5361/xostor-hyperconvergence-preview/205
As per this I did wipefs -a -f /dev/<disk> on disks which were part of XOSTOR previously, but I don't see then in the XOA UI when I go to create new XOSTOR.

Thanks.
