# Test remote copy operation (CEPH_OSD_OP_COPY_FROM) with several combinations
# of both object sizes and copy sizes.  It also uses several combinations of
# copy ranges.  For example, copying the 1st object in the src file into
# 1) the beginning (1st object) of dst file, 2) the end (last object) of dst
# file and 3) the middle of the dst file.
