I noticed that Samba master if mount with "posix" then FSCTL_SRV_COPYCHUNK_WRITE will return "STATUS_INVALID_HANDLE" where the same thing works fine if you mount without "posix" (so looks like An easy repro is with the xfstest tool "cloner" e.g ./src/cloner /mnt/aio-testfile /mnt/clone-of-aio-testfile It works fine to other servers (e.g. to ksmbd with or without "posix" mount option) -- Thanks, Steve
