kubectl get jobs -n trilio-openstack
kubectl get pv -n trilio-openstack | grep nfs (Only if backup target was NFS)
kubectl get pvc -n trilio-openstack | grep nfs (Only if backup target was NFS)
```

## 4] Clean TrilioVault’s OpenStack resources

```
openstack service list | grep -E 'TrilioVaultWLM|dmapi'
openstack endpoint list | grep -E 'TrilioVaultWLM|dmapi'
# Delete TrilioVault services from keystone catalog
openstack service delete TrilioVaultWLM
openstack service delete dmapi
# Verify TrilioVault services and endpoints got cleaned. Following command output should be empty.
openstack service list | grep -E 'TrilioVaultWLM|dmapi'
openstack endpoint list | grep -E 'TrilioVaultWLM|dmapi'
# Login to database and clean TrilioVault's databases and db users.
MYSQL_DBADMIN_PASSWORD=`kubectl -n openstack get secrets/mariadb-dbadmin-password --template={{.data.MYSQL_DBADMIN_PASSWORD}} | base64 -d`
kubectl -n openstack exec -it mariadb-server-0 -- bash
mysql -u root -p${MYSQL_DBADMIN_PASSWORD} -e "REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'dmapi'@'%%';"
mysql -u root -p${MYSQL_DBADMIN_PASSWORD} -e "DROP USER 'dmapi'@'%%';"
mysql -u root -p${MYSQL_DBADMIN_PASSWORD} -e "DROP DATABASE dmapi;"
mysql -u root -p${MYSQL_DBADMIN_PASSWORD} -e "REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'workloadmgr'@'%%';"
mysql -u root -p${MYSQL_DBADMIN_PASSWORD} -e "DROP USER 'workloadmgr'@'%%';"
mysql -u root -p${MYSQL_DBADMIN_PASSWORD} -e "DROP DATABASE workloadmgr;"
```

## 5] Unmount the targets from All Worker and Master Nodes

```
umount /var/lib/trilio/triliovault-mounts/<base64>
```

Repeat this on **each worker and master node** where the target was mounted.
