Cloning of page-compressed data is supported. The following requirements apply when cloning remote data:
The recipient file system must support sparse files and hole punching for hole punching to occur on the recipient.
The donor and recipient file systems must have the same block size. If file system block sizes differ, an error similar to the following is reported: ERROR 3868 (HY000): Clone Configuration FS Block Size: Donor value: 114688 is different from Recipient value: 4096.
