> Storage types other than NFS/VMFS can't overprovision
> -----------------------------------------------------

> Key: CLOUDSTACK-5806
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5806
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.2.0, 4.3.0, Future
> Reporter: Marcus Sorensen
> Assignee: edison su
> Priority: Critical
> Fix For: 4.4.0
>
>
> Edison, Mike, or myself can probably fix this. Mgmt server hardcodes storage
> types that can overprovision. Need to fix this.
> Edison suggests:
> We can move it to storage driver's capabilities method.
> Each storage driver can report its capabilities in DataStoreDriver->
> getCapabilities(), which returns a map[String, String], we can change the
> signature to map[String, Object]
> In CloudStackPrimaryDataStoreDriverImpl(the default storage driver)->
> getCapabilities, which can return something like:
> Var comparator = new storageOverProvision() {
> Public Boolean isOverProvisionSupported(DataStore store) {
> Var storagepool = (PrimaryDataStoreInfo)store;
> If (store.getPoolType() == NFS or VMFS) {
> Return true;
> }
> };
> };
> Var caps = new HashMap[String, Object]();
> Caps.put("storageOverProvision", comparator);
> Return caps;
> }
> Whenever, other places in mgt server want to check the capabilities of
> overprovision, we can do the following:
> Var primaryStore = DataStoreManager. getPrimaryDataStore(primaryStoreId);
> var caps = primaryStore. getDriver().getCapabilities();
> var overprovision = caps.get("storageOverProvision");
> var result = overprovision. isOverProvisionSupported(primaryStore);
