>
> The quota and consume of the file's ancestors are not handled when the
> storage policy of the file is changed. For example:
> First I set quota StorageType.SSD 2*fileSpace to the parent dir;
> Then I create a file with len fileSpace with \{DISK,DISK,DISK} under it;
> Finally I change the storage policy of the file to ALLSSD_STORAGE_POLICY_NAME
> and expect a QuotaByStorageTypeExceededException. But there isn't any
> exception.
> I'm not sure it is a bug or originally designed to skip the quota check. But
> having the check does make sense. I'll upload a unit test to show the case.
