Code Issue
If all volumes have been removed from storage_pool then capacity checker does not update the
op_host_capacity.

StorageManagerImpl.java

{noformat}
public void createCapacityEntry(StoragePoolVO storagePool, short capacityType, long allocated)
{
..
..
..

} else {
            CapacityVO capacity = capacities.get(0);
            if (capacity.getTotalCapacity() != totalOverProvCapacity || allocated != 0L ||
capacity.getCapacityState() != capacityState) { // Faulty Cade allocated != 0L 
                capacity.setTotalCapacity(totalOverProvCapacity);
                capacity.setUsedCapacity(allocated);
                capacity.setCapacityState(capacityState);
                _capacityDao.update(capacity.getId(), capacity);
            }
        }

>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: Management Server

> Disksizeallocated of PrimaryStorage is different from the total size of a volume.
> steps to reproduce:
> 1. create another primary storage( apart from default) with storage tag (say tag1)
> 2. create a disk offering with storage tag as that step1.
> 3. create a data disk with above disk offering.
> 4. attach the disk to vm.
> 5. when capacity checker thread runs it will update the used_capacity. Note down the
op_host_capacity details for pool created in step1.
> 6. detach the disk and destroy the volume.
> 7. when capacity checker thread runs it will not update the used_capacity to 0.
