Hello, First time i've sent to this group but I am trying to figure out the cause of this. Normal copy is working fine, but then if I use --reflink it says invalid argument. Not sure how to read some of this, but here is the strace. I'm running kernel v4.15 Here is the full output of strace. I ran a strace on normal copy and most looks similar so I'm not able to figure out much here... https://pastebin.com/raw/YmQ8FvCH
