Issue

Certain applications, such as SQL Server and SAP HANA, issue large truncations to files as part of reclaim operations. When a large file that is sparse, compressed, or cloned is truncated, ONTAP defers the deallocation of the file blocks by assigning them to a separate file and calculates the block counts of each piece of the original file. In a very large file with holes, compressed blocks, or cloned blocks, the calculation of the block count might cause a delay in the consistency point (CP). If the delay exceeds the ten-minute limit, it leads to a controller disruption.
