xcp fails to copy from btrfs to exfat #26

Copy link

Copying a file from a btrfs source to an exfat destination fails with the error:

Error: Operation not supported (os error 95)

However, both cp and rsync have no issues copying the file. rsync with -P even displays the progress correctly.

xcp: 0.9.1
rust: 1.63.0-1
kernel: 5.18.18
OS: Fedora 36
Arch: x86_64

I had similar error while coping from sshfs to glusterfs.

$ xcp -v aaa.gz /mnt/gluserfs/bbb/
12:44:17 [INFO] Copying source "aaa.gz" to "/mnt/gluserfs/bbb/"
12:44:17 [INFO] Worker: Copy "aaa.gz" -> "/mnt/gluserfs/bbb/aaa.gz"
12:44:17 [INFO] Worker received shutdown command.
Error: Operation not supported (os error 95)

$ echo $?
1

strace:
