It should work as you like. But it needs some considerations. The client
will use RO volumes as long as possible. But if it comes across a RW
volume while traversing the path leading to a file, it will switch over
and only use RW from there on. So, you need to make sure that every
volume a client needs to traverse to get to a file has an RO clone (even
if its on the same disk - it does not occupy space there).

HTH! Tino.
