Issue/Introduction

• Creating a new replication in VMware Cloud Director Availability fails with an unexpected error.
• In the /opt/vmware/h4/cloud/log/cloud.log file on the Replication Manager appliance, an error similar to the following can be seen:
  
  Unexpected VMware Cloud Director error. [ UI-########-####-####-####-############-####-##-##-########-####-####-####-############ ] The operation failed because no suitable resource was found. Out of 1 candidate hubs: 1 hubs eliminated because: No valid storage containers found for VirtualMachine "########-####-####-####-############". All ## available storage containers were filtered out as being invalid. Rejected hubs: resgroup-#### Storage containers were rejected for the following reasons: ## storage containers rejected because: Threshold would be violated. Rejected storage containers:... ## storage containers rejected because: They do not have enough storage capacity. Rejected storage containers:... storage containers rejected because: They do not support the required storage policy: <storage policy name>. Rejected storage containers:... - PlacementException NO_FEASIBLE_PLACEMENT_SOLUTION

Environment

VMware Cloud Director Availability 4.7.3.x
VMware Cloud Director Availability 4.7.4

Cause

When creating a new replication to a cloud site, the destination VMware Cloud Director Availability (VCDA) solicits the underlying VMware Cloud Director (VCD) implementation for a storage location on the selected storage policy. If VCD is unable to determine a location with sufficient space without violating the container threshold settings, the placement engine will return an error indicating the failure and the replication will fail to be created.

Resolution

Adjust the underlying VCD so that at least one storage container on the selected storage policy has sufficient space to accommodate the replication files without violating the configured red and yellow thresholds. For more information, please refer to the following article:
