Hello list,
Is it correct behavior during copy to thicking rbd image?
igor@hv03:~$ rbd create rbd/test -s 1024
igor@hv03:~$ rbd diff rbd/test | awk '{ SUM += $2 } END { print SUM/1024/1024 " MB" }'
0 MB
igor@hv03:~$ rbd copy rbd/test rbd/cloneoftest
Image copy: 100% complete...done.
igor@hv03:~$ rbd diff rbd/cloneoftest | awk '{ SUM += $2 } END { print SUM/1024/1024 " MB" }'
1024 MB
