Hi,

If the 'btrfs' executable is 32 bits and the kernel is 64 bits,
then 'btrfs replace status' and 'btrfs replace start' commands will fail with error message:
ERROR: ioctl(DEV_REPLACE_STATUS) failed on "/mnt/data1":Inappropriate ioctl for device

Other commands seem to work properly.

Regards,
Hubert Tonneau
