Abstract
A method for data storage includes sending write commands to a first storage node, for storing data in a data volume on the first storage node. In response to a decision to create a copy of the data volume on a second storage node, (i) the write commands are sent both to the first storage node and to the second storage node, and (ii) a snapshot of the data volume is created and sent from the first storage node to the second storage node. The copy of the data volume is created by the second storage node based on the snapshot and on one or more of the write commands received at the second storage node.
