Environment

VMware Cloud Director

Cause

vpostgres service fails to start when the sizing (CPU and memory) on newly deployed standby cell does not match with the primary cell. 

 

Resolution

All database cells in the cluster must be deployed with identical sizing (CPU and memory). Please refer these docs for more information:
VMware Cloud Director Appliance Sizing Options 10.4 
VMware Cloud Director Appliance Sizing Options 10.5 
VMware Cloud Director Appliance Sizing Options 10.6
