VMware Cloud Director reports NO_FEASIBLE_PLACMENT when deploying vApps

Issue/Introduction

VM Placement in VCD fails with:

Out of 0 available storage containers only 1 were valid, and no solution could be computed across these remaining storage containers. Rejected hubs: resgroup-XXXX Storage containers were rejected for the following reasons: 1 storage containers rejected because: The item is already on a valid datastore: datastore-XXX.

Environment

• 10.3
• 10.4
• 10.5
• 10.6

Cause

• Datastores in vCenter have an alert describing usage limits.
• Thresholds on Datastores in vCenter have been breached.
• Java.lang.IllegalArgumentException entries in the vcloud-containter-debug files describing the datastore is not valid
• usedCapacityMb is larger than totalCapacityMb

Example:

StoragePlacementAlgorithmUtils | Container [vcId=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX, moref=datastore-XXXX] is not valid.
java.lang.IllegalArgumentException: Container moref://XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/Datastore#datastore-XXXX has usedCapacityMb: XXXXXXXX > totalCapacityMb: XXXXXXXX

 

Resolution

If total storage in vCenter is more than enough to cater for the vApp, all alarms and alerts on the Datastores must be cleared along with a reduction of the Yellow and Red thresholds. By default, the Yellow threshold is 25% of the capacity of the datastore and the Red threshold is 15%
