Subject Re: Cloudstack System Capacity - VMFS Storage
Date Thu, 10 Oct 2013 21:02:01 GMT
Storage 461GB/5TB
Primary Storage Allocated 2.5TB/5TB

I am not running out of real space, but when the allocated storage
gets too high I cannot deploy vms. The storage.overprovisioning.factor
multiplier is not having any effect in allowing me to overprovision
storage.
