Environment

7.x

Cause

• This problem occurs when there is communication issues between Openstack and vCenter Storage Policy-Based Management (SPBM) service, and the underlying vSAN policies incompatible.
• This would be the reason that nova failed stating Storage policy did not match any datastores.

Resolution

 

1. Navigate to VM Storage Policies in vCenter GUI
2. Check for the policy for which the error is being reported under the list of policies.
3. Once identified the exact policy, click on it 
4. Check for "INCOMPATIBLE" list under Storage Compatibility tab.
5. Check for the datastore <VSAN Datastore Name> (Specific to environment and the one which the error is reported) and if it is listed in the "INCOMPATIBLE" datastore list under Storage Policy name.
6. Once validated check and make datastore  <VSAN Datastore Name>"  compatible for Storage Policy.
