Error: "Storage policy "############" cannot be deleted since it is currently in use." when detaching storage policy from Organization VDCs

Products

• VMware Cloud Director

Issue/Introduction

• Deleting the storage policy as per the steps in the documentation.
• Storage policy shows some or no usage as per the UI metrics.
• Migrating storage as per the steps in the documentation did not work.

Environment

VMware Cloud Director 10.5.x

VMware Cloud Director 10.6.x

Cause

1. If there are tenant objects - vApps/vApp templates/Media that prevent the removal of the storage policy.
2. If the catalogs in the organization are backed by a specific organization VDC(OVDC) and the storage policy to-be-removed.

Resolution

To resolve the issue, any objects leveraging the storage policy needs to be identified and unlinked. Any stale vApps/vApp templates/media can be identified from the database and then verified in the UI with the steps below:

1. Note the name of the affected OVDC and the storage policy to-be-removed. The scripts listed in Step 3 and 4 will need these names and have to be replaced accordingly.

2. Connect to the VCD database via SSH or pgAdmin

• SSH to any of the appliance nodes
• Run the command: sudo -u postgres psql vcloud

3. To find the list of vApps or vApp templates referencing the storage policy available on the tenant

SELECT
vapp_vm.name AS vapp_vm_name,
vm_container.name as vapp_name,
vm_container.sg_type as type,
vm.moref as moref,
vapp_vm_sclass_metrics.storage_used_mb
FROM vapp_vm_sclass_metrics
LEFT JOIN vapp_vm ON vapp_vm.id = vapp_vm_sclass_metrics.vapp_vm_id
LEFT JOIN vm_container ON vm_container.sg_id = vapp_vm.vapp_id
left join vm on vm.id = vapp_vm.svm_id
JOIN vdc_logical_resource ON vdc_logical_resource.id = vapp_vm_sclass_metrics.storage_class_lr_id
JOIN org_prov_vdc ON org_prov_vdc.id = vdc_logical_resource.vdc_id
WHERE org_prov_vdc.name = 'Organization VDC Name' AND vdc_logical_resource.name = 'Storage policy to-be-removed';

Note: type column with value 1 would mean it is a normal vApp and value 2 would mean it is a vApp template.

4. To find the list of media items that may still be present in the storage profile to be removed.

SELECT
org_prov_vdc.name AS org_vdc_name,
logical_disk.id AS logical_disk_id,
logical_disk.name AS logical_disk_name,
logical_disk.logical_disk_type,
logical_disk.creation_status AS logical_creation_status,
COALESCE((logical_disk.size_bytes::numeric / 1048576.0), 0::numeric) AS storage_used_mb
FROM logical_disk
LEFT JOIN ldisk_storage_class_join ON logical_disk.id = ldisk_storage_class_join.logical_disk_id
LEFT JOIN ldisk_fo_join ON logical_disk.id = ldisk_fo_join.logical_disk_id
LEFT JOIN vm_disk ON vm_disk.disk_id = ldisk_fo_join.fo_id
LEFT JOIN org_prov_vdc ON org_prov_vdc.id = logical_disk.org_vdc_id
LEFT JOIN vdc_logical_resource ON vdc_logical_resource.id = ldisk_storage_class_join.storage_class_id
where org_prov_vdc.name like '%Organization VDC Name%';

5. For the catalogs in the organizations, verify the Storage Policies settings as per the documentations below:

• Step 3 as per View Catalogs in the VMware Cloud Director Tenant Portal
• Step 4 as per Create a Catalog in the VMware Cloud Director Tenant Portal to edit the storage policy.

 6. Migrate the VMs/vApps/media identified in Steps 3, 4 or change the storage policy on them.

Edit the Default Storage Policy of a vApp Template
Edit Virtual Machine Properties in the VMware Cloud Director Tenant Portal

Edit a Named Disk
