Splitting a FlexClone volume from its parent removes any space optimizations that are currently employed by the FlexClone volume. After the split, both the FlexClone volume and the parent volume require the full space allocation determined by their space guarantees. The FlexClone volume becomes a normal FlexVol volume.
The following list contains facts about the clone splitting operation that you should know:
- When you split a FlexClone volume from its parent, all existing Snapshot copies of the FlexClone volume are deleted.
- No new Snapshot copies can be created of the FlexClone volume for the duration of the split operation.
- Because the clone-splitting operation is a copy operation that might take considerable time to carry out, Data ONTAP provides the vol clone split stop and vol clone split status commands to stop or check the status of a clone-splitting operation.
- The clone-splitting operation proceeds in the background and does not interfere with data access to either the parent or the clone volume.
- If you take the FlexClone volume offline while splitting is in progress, the operation is suspended; when you bring the FlexClone volume back online, the splitting operation resumes.
- Once a FlexClone volume and its parent volume have been split, they cannot be rejoined.
