You should keep several considerations in mind when working with FlexClone files and FlexClone LUNs.
You can clone a complete file, sub-file, LUN, or sub-LUN.
To clone a sub-file or sub-LUN, you should know the block range of the parent entity and clone entity.
Deleting a parent file or LUN has no impact on the FlexClone files or FlexClone LUNs.
If a FlexVol volume containing FlexClone files and LUNs has the fractional reserve set to zero, you must follow extra configuration and management requirements to ensure that the applications accessing the FlexVol volume do not receive errors due to lack of space (ENOSPC).
