1) No problems during this step, the procedure just needs a few seconds.
reflink is a binary. See reflink --help
Yes, it is a cluster filesystem. I do the procedure just on one node,
so i don't have duplicates.
2) just with "cp source destination" to a NAS.
Yes, the problems appear during this step.
