Clone volume split of clone volume from parent volume with data tiered to object store

A non-transitory machine readable medium comprising instructions for performing a method, which when executed by a machine, causes the machine to perform operations comprising:

• receiving a request to split a clone volume from a parent volume whose data is stored within objects of an object store, wherein splitting the clone volume includes copying parent objects of the parent volume to create child objects;
• creating child object identifiers for the child objects;
• populating a reverse map with reverse map entries, wherein a reverse map entry includes a child object identifier for a child object and a parent object identifier of a parent object to copy as the child object;
• and
• instructing the object store to copy the parent objects as the child objects for splitting the clone volume from the parent volume, wherein the reverse map is used to verify that the child objects are successfully created with valid data.

A computing device comprising:

• a memory storing instructions;
• and
• a processor coupled to the memory, the processor configured to execute the instructions to perform operations comprising:
• receiving a request to split a clone volume from a parent volume whose data is stored within objects of an object store, wherein splitting the clone volume includes copying parent objects of the parent volume to create child objects;
• creating child object identifiers for the child objects;
• populating a reverse map with reverse map entries, wherein a reverse map entry includes a child object identifier for a child object and a parent object identifier of a parent object to copy as the child object;
• and
• instructing the object store to copy the parent objects as the child objects for splitting the clone volume from the parent volume, wherein the reverse map is used to verify that the child objects are successfully created with valid data.
