    Description

      Currently the MDT object creation code doesn't take the OST Pool quota usage or limits into account when creating a new file. When using an OST Pool in the file layout, it should be checking if the user is over quota, and using the OST Pool Spill feature to redirect that file creation to another pool. That would allow a more graceful handling of exceeding OST Pool Quota, allowing the application to continue running (at a lower performance), rather than failing outright.
