As Darren replied while I was typing this, you can't have dangerous
data written all over a cluster which automatically moves data around,
Unfortunately this is impossible to achieve.
Unless you can guarantee that the same physical pieces of disk are going to
always be mapped to the same parts of the RBD device then you will leave data
lying around on the array. How easy it is to recover is a bit of a question
about how valuable
