Environment

VMware Cloud Director 10.4.3, 10.6.x
Telco Cloud Platform 4.0, 4.0.1

Cause

• You can configure low disk space thresholds (red/yellow thresholds) on storage containers in Cloud Director.  
• This issue occurs if the disk is being deployed to a storage container/datastore which has breached the configured storage thresholds.
• The Cloud Director placement engine stops placing objects on the datastore when this occurs.

Resolution

Adjust the storage container threshold

1. Inspect the current storage capacity utilization on the storage container/datastore(s).
2. Inspect the configured red/yellow thresholds in Cloud Director.
   
   Configure Low Disk Space Thresholds for a Provider Virtual Data Center Storage Container
   
   View the Datastores and Datastore Clusters on a Provider Virtual Data Center in Your VMware Cloud Director

Based on your inspection of the environment, take appropriate action to either make available additional capacity on the storage container/datastore(s) or alternatively modify the red/yellow threshold settings if appropriate.
