Why does flex volume clone split take a long time?
Applies to
- ONTAP 9
Answer
Clone-splitting is a copy operation that might take considerable time and resources to carry out due to the following reasons:
- Free blocks in the aggregate are used to copy blocks shared between the parent and the clone
- Clone-splitting incurs disk I/O operations, and can potentially compete with other disk operations in the aggregate
- Clone-splitting uses some available CPU resources, which may impact the performance of a fully-loaded storage controller
- The clone split operation runs in the background and priorities are set in such a way that it does not significantly impact foreground operations.
