oh, I never try to clone(copy) between 2 rbd storage, only from local to rbd , or rbd to local.

maybe can you try without '-t writeback ?'

Does it work if you try to copy from rbd to local by example ?

activate volume vmstorssd1:vm-169-disk-1 
copy vmstorssd1:vm-166-disk-1 to vmstorssd1:vm-169-disk-1 
(0.00/100%)
